+# Contributor Guide
+
+## Running a development build
+
+Install a node version manager such as [fnm](https://github.com/Schniz/fnm?tab=readme-ov-#installation).
+
+On Windows, it's also recommended to [upgrade your PowerShell version](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.5#winget), we're using 7.
+
+Then in the repo run the following to install and use the node version specified in `.nvmrc`. You might need to specify your processor architecture with `--arch arm64` or `--arch x64` if it's not autodetected.
+
+```
+fnm install --corepack-enabled
+fnm use
+```
+
+Install the NPM dependencies with:
+
+```
+npm install
+```
+
+This project uses a lot of Rust compiled to [WASM](https://webassembly.org/) within it. We have package scripts to run rustup, see `package.json` for reference:
+
+```
+# macOS/Linux
+npm run install:rust
+npm run install:wasm-pack:sh
+
+# Windows
+npm run install:rust:windows
+npm run install:wasm-pack:cargo
+```
+
+Then to build the WASM layer, run:
+
+```
+# macOS/Linux
+npm run build:wasm
+
+# Windows
+npm run build:wasm:windows
+```
+
+Or if you have the `gh` cli installed and want to download the latest main wasm bundle. Note that on Windows, you need to associate .ps1 files with PowerShell, which can be done via the right click menu, selecting `C:\Program Files\PowerShell\7\pwsh.exe`, and you can install tools like `gh` via `npm run install:tools:windows`.
+
+```
+# macOS/Linux
+npm run fetch:wasm
+
+# Windows
+npm run fetch:wasm:windows
+```
+
+That will build the WASM binary and put in the `public` dir (though gitignored).
+
+Finally, to run the web app only, run:
+
+```
+npm start
+```
+
+If you're not a Zoo employee you won't be able to access the dev environment, you should copy everything from `.env.production` to `.env.development.local` to make it point to production instead, then when you navigate to `localhost:3000` the easiest way to sign in is to paste `localStorage.setItem('TOKEN_PERSIST_KEY', "your-token-from-https://zoo.dev/account/api-tokens")` replacing the with a real token from https://zoo.dev/account/api-tokens of course, then navigate to `localhost:3000` again. Note that navigating to `localhost:3000/signin` removes your token so you will need to set the token again.
+
+### Development environment variables
+
+The Copilot LSP plugin in the editor requires a Zoo API token to run. In production, we authenticate this with a token via cookie in the browser and device auth token in the desktop environment, but this token is inaccessible in the dev browser version because the cookie is considered "cross-site" (from `localhost` to `zoo.dev`). There is an optional environment variable called `VITE_KC_DEV_TOKEN` that you can populate with a dev token in a `.env.development.local` file to not check it into Git, which will use that token instead of other methods for the LSP service.
+
+### Developing in Chrome
+
+Chrome is in the process of rolling out a new default which
+[blocks Third-Party Cookies](https://developer.chrome.com/en/docs/privacy-sandbox/third-party-cookie-phase-out/).
+If you're having trouble logging into the `modeling-app`, you may need to
+enable third-party cookies. You can enable third-party cookies by clicking on
+the eye with a slash through it in the URL bar, and clicking on "Enable
+Third-Party Cookies".
+
+## Desktop
+
+To spin up the desktop app, `npm install` and `npm run build:wasm` need to have been done before hand then:
+
+```
+npm run tron:start
+```
+
+This will start the application and hot-reload on changes.
+
+Devtools can be opened with the usual Command-Option-I (macOS) or Ctrl-Shift-I (Linux and Windows).
+
+To package the app for your platform with electron-builder, run `npm run tronb:package:dev` (or `npm run tronb:package:prod` to point to the .env.production variables).
+
+## Checking out commits / Bisecting
+
+Which commands from setup are one off vs. need to be run every time?
+
+The following will need to be run when checking out a new commit and guarantees the build is not stale:
+
+```bash
+npm install
+npm run build:wasm
+npm start
+```
+
+## Before submitting a PR
+
+Before you submit a contribution PR to this repo, please ensure that:
+
+- There is a corresponding issue for the changes you want to make, so that discussion of approach can be had before work begins.
+- You have separated out refactoring commits from feature commits as much as possible
+- You have run all of the following commands locally:
+  - `npm run fmt`
+  - `npm run tsc`
+  - `npm run test`
+  - Here they are all together: `npm run fmt && npm run tsc && npm run test`
+
+## Release a new version
+
+#### 1. Create a 'Cut release $VERSION' issue
+
+It will be used to document changelog discussions and release testing.
+
+https://github.com/KittyCAD/modeling-app/issues/new
+
+#### 2. Push a new tag
+
+Create a new tag and push it to the repo. The `semantic-release.sh` script will automatically bump the minor part, which we use the most. For instance going from `v0.27.0` to `v0.28.0`.
+
+```
+VERSION=$(./scripts/semantic-release.sh)
+git tag $VERSION
+git push origin --tags
+```
+
+This will trigger the `build-apps` workflow, set the version, build & sign the apps, and generate release files as well as updater-test artifacts.
+
+The workflow should be listed right away [in this list](https://github.com/KittyCAD/modeling-app/actions/workflows/build-apps.yml?query=event%3Apush)).
+
+#### 3. Manually test artifacts
+
+##### Release builds
+
+The release builds can be found under the `out-{arch}-{platform}` zip files, at the very bottom of the `build-apps` summary page for the workflow (triggered by the tag in 2.).
+
+Manually test against this [list](https://github.com/KittyCAD/modeling-app/issues/3588) across Windows, MacOS, Linux and posting results as comments in the issue.
+
+##### Updater-test builds
+
+The other `build-apps` output in the release `build-apps` workflow (triggered by 2.) is `updater-test-{arch}-{platform}`. It's a semi-automated process: for macOS, Windows, and Linux, download the corresponding updater-test artifact file, install the app, run it, expect an updater prompt to a dummy v0.255.255, install it and check that the app comes back at that version.
+
+The only difference with these builds is that they point to a different update location on the release bucket, with this dummy v0.255.255 always available. This helps ensuring that the version we release will be able to update to the next one available.
+
+If the prompt doesn't show up, start the app in command line to grab the electron-updater logs. This is likely an issue with the current build that needs addressing (or the updater-test location in the storage bucket).
+
+```
+# Windows (PowerShell)
+& 'C:\Program Files\Zoo Design Studio\Zoo Design Studio.exe'
+
+# macOS
+/Applications/Zoo\ Modeling\ App.app/Contents/MacOS/Zoo\ Modeling\ App
+
+# Linux
+./Zoo Design Studio-{version}-{arch}-linux.AppImage
+```
+
+#### 4. Publish the release
+
+Head over to https://github.com/KittyCAD/modeling-app/releases/new, pick the newly created tag and type it in the _Release title_ field as well.
+
+Hit _Generate release notes_ as a starting point to discuss the changelog in the issue. Once done, make sure _Set as the latest release_ is checked, and hit _Publish release_.
+
+A new `publish-apps-release` will kick in and you should be able to find it [here](https://github.com/KittyCAD/modeling-app/actions?query=event%3Arelease). On success, the files will be uploaded to the public bucket as well as to the GitHub release, and the announcement on Discord will be sent.
+
+#### 5. Close the issue
+
+If everything is well and the release is out to the public, the issue tracking the release shall be closed.
+
+## Fuzzing the parser
+
+Make sure you install cargo fuzz:
+
+```bash
+$ cargo install cargo-fuzz
+```
+
+```bash
+$ cd rust/kcl-lib
+
+# list the fuzz targets
+$ cargo fuzz list
+
+# run the parser fuzzer
+$ cargo +nightly fuzz run parser
+```
+
+For more information on fuzzing you can check out
+[this guide](https://rust-fuzz.github.io/book/cargo-fuzz.html).
+
+## Tests
+
+### Playwright tests
+
+Prepare these system dependencies:
+
+- Set $token from https://zoo.dev/account/api-tokens
+
+#### Snapshot tests (Google Chrome on Ubuntu only)
+
+Only Ubunu and Google Chrome is supported for the set of tests evaluating screenshot snapshots.
+If you don't run Ubuntu locally or in a VM, you may use a GitHub Codespace.
+```
+npm run playwright -- install chrome
+npm run test:snapshots
+```
+You may use `-- --update-snapshots` as needed.
+
+#### Electron flow tests (Chromium on Ubuntu, macOS, Windows)
+
+```
+npm run playwright -- install chromium
+npm run test:playwright:electron:local
+```
+You may use `-- -g "my test"` to match specific test titles, or `-- path/to/file.spec.ts` for a test file.
+
+#### Debugger
+
+However, if you want a debugger I recommend using VSCode and the `playwright` extension, as the above command is a cruder debugger that steps into every function call which is annoying.
+With the extension you can set a breakpoint after `waitForDefaultPlanesVisibilityChange` in order to skip app loading, then the vscode debugger's "step over" is much better for being able to stay at the right level of abstraction as you debug the code.
+
+If you want to limit to a single browser use `--project="webkit"` or `firefox`, `Google Chrome`
+Or comment out browsers in `playwright.config.ts`.
+
+note chromium has encoder compat issues which is why were testing against the branded 'Google Chrome'
+
+You may consider using the VSCode extension, it's useful for running individual threads, but some some reason the "record a test" is locked to chromium with we can't use. A work around is to us the CI `npm run playwright codegen -b wk --load-storage ./store localhost:3000`
+
+<details>
+<summary>
+
+Where `./store` should look like this
+
+</summary>
+
+```JSON
+{
+  "cookies": [],
+  "origins": [
+    {
+      "origin": "http://localhost:3000",
+      "localStorage": [
+        {
+          "name": "store",
+          "value": "{\"state\":{\"openPanes\":[\"code\"]},\"version\":0}"
+        },
+        {
+          "name": "persistCode",
+          "value": ""
+        },
+        {
+          "name": "TOKEN_PERSIST_KEY",
+          "value": "your-token"
+        }
+      ]
+    }
+  ]
+}
+```
+
+</details>
+
+However because much of our tests involve clicking in the stream at specific locations, it's code-gen looks `await page.locator('video').click();` when really we need to use a pixel coord, so I think it's of limited use.
+
+### Unit and component tests
+
+If you already haven't, run the following:
+
+```
+npm
+npm run build:wasm
+npm start
+```
+
+and finally:
+
+```
+npm run test:unit
+```
+
+For individual testing:
+
+```
+npm run test abstractSyntaxTree -t "unexpected closed curly brace" --silent=false
+```
+
+Which will run our suite of [Vitest unit](https://vitest.dev/) and [React Testing Library E2E](https://testing-library.com/docs/react-testing-library/intro) tests, in interactive mode by default.
+
+### Rust tests
+
+Prepare these system dependencies:
+
+- Set `$KITTYCAD_API_TOKEN` from https://zoo.dev/account/api-tokens
+- Install `just` following [these instructions](https://just.systems/man/en/packages.html)
+
+then run tests that target the KCL language:
+
+```
+npm run test:rust
+```
+
+### Logging
+
+To display logging (to the terminal or console) set `ZOO_LOG=1`. This will log some warnings and simple performance metrics. To view these in test runs, use `-- --nocapture`.
+
+To enable memory metrics, build with `--features dhat-heap`.

+Design Studio is our take on what a modern modelling experience can be. It is applying several lessons learned in the decades since most major CAD tools came into existence:
 
 - All artifacts—including parts and assemblies—should be represented as human-readable code. At the end of the day, your CAD project should be "plain text"
   - This makes version control—which is a solved problem in software engineering—trivial for CAD
 - All GUI (or point-and-click) interactions should be actions performed on this code representation under the hood
-  - This unlocks a hybrid approach to modeling. Whether you point-and-click as you always have or you write your own KCL code, you are performing the same action in Modeling App

-[Original demo slides](https://github.com/user-attachments/files/19010536/demo.pdf)
+We recommend downloading the latest application binary from our [releases](https://github.com/KittyCAD/modeling-app/releases) page. If you don't see your platform or architecture supported there, please file an issue.
 
-## Get started
+If you'd like to try out upcoming changes sooner, you can also download those from our [nightly releases](https://zoo.dev/modeling-app/download/nightly) page.

+## Developing
 
-## Running a development build
-
-Install a node version manager such as [fnm](https://github.com/Schniz/fnm?tab=readme-ov-#installation).
-
-On Windows, it's also recommended to [upgrade your PowerShell version](https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.5#winget), we're using 7.
-
-Then in the repo run the following to install and use the node version specified in `.nvmrc`. You might need to specify your processor architecture with `--arch arm64` or `--arch x64` if it's not autodetected.
-
-```
-fnm install --corepack-enabled
-fnm use
-```
-
-Install the NPM dependencies with:
-
-```
-yarn install
-```
-
-This project uses a lot of Rust compiled to [WASM](https://webassembly.org/) within it. We have package scripts to run rustup, see `package.json` for reference:
-
-```
-# macOS/Linux
-yarn install:rust
-yarn install:wasm-pack:sh
-
-# Windows
-yarn install:rust:windows
-yarn install:wasm-pack:cargo
-```
-
-Then to build the WASM layer, run:
-
-```
-# macOS/Linux
-yarn build:wasm
-
-# Windows
-yarn build:wasm:windows
-```
-
-Or if you have the `gh` cli installed and want to download the latest main wasm bundle. Note that on Windows, you need to associate .ps1 files with PowerShell, which can be done via the right click menu, selecting `C:\Program Files\PowerShell\7\pwsh.exe`, and you can install tools like `gh` via `yarn install:tools:windows`.
-
-```
-# macOS/Linux
-yarn fetch:wasm
-
-# Windows
-yarn fetch:wasm:windows
-```
-
-That will build the WASM binary and put in the `public` dir (though gitignored).
-
-Finally, to run the web app only, run:
-
-```
-yarn start
-```
-
-If you're not a Zoo employee you won't be able to access the dev environment, you should copy everything from `.env.production` to `.env.development.local` to make it point to production instead, then when you navigate to `localhost:3000` the easiest way to sign in is to paste `localStorage.setItem('TOKEN_PERSIST_KEY', "your-token-from-https://zoo.dev/account/api-tokens")` replacing the with a real token from https://zoo.dev/account/api-tokens of course, then navigate to `localhost:3000` again. Note that navigating to `localhost:3000/signin` removes your token so you will need to set the token again.
-
-### Development environment variables
-
-The Copilot LSP plugin in the editor requires a Zoo API token to run. In production, we authenticate this with a token via cookie in the browser and device auth token in the desktop environment, but this token is inaccessible in the dev browser version because the cookie is considered "cross-site" (from `localhost` to `dev.zoo.dev`). There is an optional environment variable called `VITE_KC_DEV_TOKEN` that you can populate with a dev token in a `.env.development.local` file to not check it into Git, which will use that token instead of other methods for the LSP service.
-
-### Developing in Chrome
-
-Chrome is in the process of rolling out a new default which
-[blocks Third-Party Cookies](https://developer.chrome.com/en/docs/privacy-sandbox/third-party-cookie-phase-out/).
-If you're having trouble logging into the `modeling-app`, you may need to
-enable third-party cookies. You can enable third-party cookies by clicking on
-the eye with a slash through it in the URL bar, and clicking on "Enable
-Third-Party Cookies".
-
-## Desktop
-
-To spin up the desktop app, `yarn install` and `yarn build:wasm` need to have been done before hand then:
-
-```
-yarn tron:start
-```
-
-This will start the application and hot-reload on changes.
-
-Devtools can be opened with the usual Command-Option-I (macOS) or Ctrl-Shift-I (Linux and Windows).
-
-To package the app for your platform with electron-builder, run `yarn tronb:package:dev` (or `yarn tronb:package:prod` to point to the .env.production variables).
-
-## Checking out commits / Bisecting
-
-Which commands from setup are one off vs. need to be run every time?
-
-The following will need to be run when checking out a new commit and guarantees the build is not stale:
-
-```bash
-yarn install
-yarn build:wasm
-yarn start # or yarn build:local && yarn serve for slower but more production-like build
-```
-
-## Before submitting a PR
-
-Before you submit a contribution PR to this repo, please ensure that:
-
-- There is a corresponding issue for the changes you want to make, so that discussion of approach can be had before work begins.
-- You have separated out refactoring commits from feature commits as much as possible
-- You have run all of the following commands locally:
-  - `yarn fmt`
-  - `yarn tsc`
-  - `yarn test`
-  - Here they are all together: `yarn fmt && yarn tsc && yarn test`
-
-## Release a new version
-
-#### 1. Create a 'Cut release $VERSION' issue
-
-It will be used to document changelog discussions and release testing.
-
-https://github.com/KittyCAD/modeling-app/issues/new
-
-#### 2. Push a new tag
-
-Create a new tag and push it to the repo. The `semantic-release.sh` script will automatically bump the minor part, which we use the most. For instance going from `v0.27.0` to `v0.28.0`.
-
-```
-VERSION=$(./scripts/semantic-release.sh)
-git tag $VERSION
-git push origin --tags
-```
-
-This will trigger the `build-apps` workflow, set the version, build & sign the apps, and generate release files as well as updater-test artifacts.
-
-The workflow should be listed right away [in this list](https://github.com/KittyCAD/modeling-app/actions/workflows/build-apps.yml?query=event%3Apush)).
-
-#### 3. Manually test artifacts
-
-##### Release builds
-
-The release builds can be found under the `out-{arch}-{platform}` zip files, at the very bottom of the `build-apps` summary page for the workflow (triggered by the tag in 2.).
-
-Manually test against this [list](https://github.com/KittyCAD/modeling-app/issues/3588) across Windows, MacOS, Linux and posting results as comments in the issue.
-
-##### Updater-test builds
-
-The other `build-apps` output in the release `build-apps` workflow (triggered by 2.) is `updater-test-{arch}-{platform}`. It's a semi-automated process: for macOS, Windows, and Linux, download the corresponding updater-test artifact file, install the app, run it, expect an updater prompt to a dummy v0.255.255, install it and check that the app comes back at that version.
-
-The only difference with these builds is that they point to a different update location on the release bucket, with this dummy v0.255.255 always available. This helps ensuring that the version we release will be able to update to the next one available.
-
-If the prompt doesn't show up, start the app in command line to grab the electron-updater logs. This is likely an issue with the current build that needs addressing (or the updater-test location in the storage bucket).
-
-```
-# Windows (PowerShell)
-& 'C:\Program Files\Zoo Modeling App\Zoo Modeling App.exe'
-
-# macOS
-/Applications/Zoo\ Modeling\ App.app/Contents/MacOS/Zoo\ Modeling\ App
-
-# Linux
-./Zoo Modeling App-{version}-{arch}-linux.AppImage
-```
-
-#### 4. Publish the release
-
-Head over to https://github.com/KittyCAD/modeling-app/releases/new, pick the newly created tag and type it in the _Release title_ field as well.
-
-Hit _Generate release notes_ as a starting point to discuss the changelog in the issue. Once done, make sure _Set as the latest release_ is checked, and hit _Publish release_.
-
-A new `publish-apps-release` will kick in and you should be able to find it [here](https://github.com/KittyCAD/modeling-app/actions?query=event%3Arelease). On success, the files will be uploaded to the public bucket as well as to the GitHub release, and the announcement on Discord will be sent.
-
-#### 5. Close the issue
-
-If everything is well and the release is out to the public, the issue tracking the release shall be closed.
-
-## Fuzzing the parser
-
-Make sure you install cargo fuzz:
-
-```bash
-$ cargo install cargo-fuzz
-```
-
-```bash
-$ cd rust/kcl-lib
-
-# list the fuzz targets
-$ cargo fuzz list
-
-# run the parser fuzzer
-$ cargo +nightly fuzz run parser
-```
-
-For more information on fuzzing you can check out
-[this guide](https://rust-fuzz.github.io/book/cargo-fuzz.html).
-
-## Tests
-
-### Playwright tests
-
-You will need a `./e2e/playwright/playwright-secrets.env` file:
-
-```bash
-$ touch ./e2e/playwright/playwright-secrets.env
-$ cat ./e2e/playwright/playwright-secrets.env
-token=<dev.zoo.dev/account/api-tokens>
-snapshottoken=<your-snapshot-token>
-```
-
-For a portable way to run Playwright you'll need Docker.
-
-#### Generic example
-
-After that, open a terminal and run:
-
-```bash
-docker run --network host  --rm --init -it playwright/chrome:playwright-x.xx.x
-```
-
-and in another terminal, run:
-
-```bash
-PW_TEST_CONNECT_WS_ENDPOINT=ws://127.0.0.1:4444/ yarn playwright test --project="Google Chrome" <test suite>
-```
-
-#### Specific example
-
-open a terminal and run:
-
-```bash
-docker run --network host  --rm --init -it playwright/chrome:playwright-1.46.0
-```
-
-and in another terminal, run:
-
-```bash
-PW_TEST_CONNECT_WS_ENDPOINT=ws://127.0.0.1:4444/ yarn playwright test --project="Google Chrome" e2e/playwright/command-bar-tests.spec.ts
-```
-
-run a specific test change the test from `test('...` to `test.only('...`
-(note if you commit this, the tests will instantly fail without running any of the tests)
-
-**Gotcha**: running the docker container with a mismatched image against your `./node_modules/playwright` will cause a failure. Make sure the versions are matched and up to date.
-
-run headed
-
-```
-yarn playwright test --headed
-```
-
-run with step through debugger
-
-```
-PWDEBUG=1 yarn playwright test
-```
-
-However, if you want a debugger I recommend using VSCode and the `playwright` extension, as the above command is a cruder debugger that steps into every function call which is annoying.
-With the extension you can set a breakpoint after `waitForDefaultPlanesVisibilityChange` in order to skip app loading, then the vscode debugger's "step over" is much better for being able to stay at the right level of abstraction as you debug the code.
-
-If you want to limit to a single browser use `--project="webkit"` or `firefox`, `Google Chrome`
-Or comment out browsers in `playwright.config.ts`.
-
-note chromium has encoder compat issues which is why were testing against the branded 'Google Chrome'
-
-You may consider using the VSCode extension, it's useful for running individual threads, but some some reason the "record a test" is locked to chromium with we can't use. A work around is to us the CI `yarn playwright codegen -b wk --load-storage ./store localhost:3000`
-
-<details>
-<summary>
-
-Where `./store` should look like this
-
-</summary>
-
-```JSON
-{
-  "cookies": [],
-  "origins": [
-    {
-      "origin": "http://localhost:3000",
-      "localStorage": [
-        {
-          "name": "store",
-          "value": "{\"state\":{\"openPanes\":[\"code\"]},\"version\":0}"
-        },
-        {
-          "name": "persistCode",
-          "value": ""
-        },
-        {
-          "name": "TOKEN_PERSIST_KEY",
-          "value": "your-token"
-        }
-      ]
-    }
-  ]
-}
-```
-
-</details>
-
-However because much of our tests involve clicking in the stream at specific locations, it's code-gen looks `await page.locator('video').click();` when really we need to use a pixel coord, so I think it's of limited use.
-
-### Unit and component tests
-
-If you already haven't, run the following:
-
-```
-yarn
-yarn build:wasm
-yarn start
-```
-
-and finally:
-
-```
-yarn test:unit
-```
-
-For individual testing:
-
-```
-yarn test abstractSyntaxTree -t "unexpected closed curly brace" --silent=false
-```
-
-Which will run our suite of [Vitest unit](https://vitest.dev/) and [React Testing Library E2E](https://testing-library.com/docs/react-testing-library/intro) tests, in interactive mode by default.
-
-### Rust tests
-
-**Dependencies**
-
-- `KITTYCAD_API_TOKEN`
-- `cargo-nextest`
-- `just`
-
-#### Setting KITTYCAD_API_TOKEN
-
-Use the production zoo.dev token, set this environment variable before running the tests
-
-#### Installing cargonextest
-
-```
-cd rust 
-cargo search cargo-nextest
-cargo install cargo-nextest
-```
-
-#### just
-
-install [`just`](https://github.com/casey/just?tab=readme-ov-file#pre-built-binaries)
-
-#### Running the tests
-
-```bash
-# With just
-# Make sure KITTYCAD_API_TOKEN=<prod zoo.dev token> is set
-# Make sure you installed cargo-nextest
-# Make sure you installed just
-cd rust 
-just test
-```
-
-```bash
-# Without just
-# Make sure KITTYCAD_API_TOKEN=<prod zoo.dev token> is set
-# Make sure you installed cargo-nextest
-cd rust 
-export RUST_BRACKTRACE="full" && cargo nextest run --workspace --test-threads=1
-```
-
-Where `XXX` is an API token from the production engine (NOT the dev environment).
-
-We recommend using [nextest](https://nexte.st/) to run the Rust tests (its faster and is used in CI). Once installed, run the tests using
-
-```
-cd rust 
-KITTYCAD_API_TOKEN=XXX cargo run nextest
-```
-
-### Mapping CI CD jobs to local commands
-
-When you see the CI CD fail on jobs you may wonder three things
-
-- Do I have a bug in my code?
-- Is the test flaky?
-- Is there a bug in `main`?
-
-To answer these questions the following commands will give you confidence to locate the issue.
-
-#### Static Analysis
-
-Part of the CI CD pipeline performs static analysis on the code. Use the following commands to mimic the CI CD jobs.
-
-The following set of commands should get us closer to one and done commands to instantly retest issues.
-
-```
-yarn test-setup
-```
-
-> Gotcha, are packages up to date and is the wasm built?
-
-```
-yarn tsc
-yarn fmt-check
-yarn lint
-yarn test:unit:local
-```
-
-> Gotcha: Our unit tests have integration tests in them. You need to run a localhost server to run the unit tests.
-
-#### E2E Tests
-
-**Playwright Electron**
-
-These E2E tests run in electron. There are tests that are skipped if they are ran in a windows, linux, or macos environment. We can use playwright tags to implement test skipping.
-
-```
-yarn test:playwright:electron:local
-yarn test:playwright:electron:windows:local
-yarn test:playwright:electron:macos:local
-yarn test:playwright:electron:ubuntu:local
-```
-
-> Why does it say local? The CI CD commands that run in the pipeline cannot be ran locally. A single command will not properly setup the testing environment locally.
-
-#### Some notes on CI
-
-The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.
-
-How to interpret failing playwright tests?
-If your tests fail, click through to the action and see that the tests failed on a line that includes `await page.getByTestId('loading').waitFor({ state: 'detached' })`, this means the test fail because the stream never started. It's you choice if you want to re-run the test, or ignore the failure.
-
-We run on ubuntu and macos, because safari doesn't work on linux because of the dreaded "no RTCPeerConnection variable" error. But linux runs first and then macos for the same reason that we limit the number of parallel tests to 1 because we limit stream connections per user, so tests would start failing we if let them run together.
-
-If something fails on CI you can download the artifact, unzip it and then open `playwright-report/data/<UUID>.zip` with https://trace.playwright.dev/ to see what happened.
-
-#### Getting started writing a playwright test in our app
-
-Besides following the instructions above and using the playwright docs, our app is weird because of the whole stream thing, which means our testing is weird. Because we've just figured out this stuff and therefore docs might go stale quick here's a 15min vid/tutorial

+
+KCL supports the usual arithmetic operators on numbers and logic operators on booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `+` | Addition |
+| `-` | Subtraction or unary negation |
+| `*` | Multiplication |
+| `/` | Division |
+| `%` | Modulus aka remainder |
+| `^` | Power, e.g., `x ^ 2` means `x` squared |
+| `&` | Logical 'and' |
+| `|` | Logical 'or' |
+| `!` | Unary logical 'not' |
+
+KCL also supports comparsion operators which operate on numbers and produce booleans:
+
+| Operator | Meaning |
+|----------|---------|
+| `==` | Equal |
+| `!=` | Not equal |
+| `<` | Less than |
+| `>` | Greater than |
+| `<=` | Less than or equal |
+| `>=` | Greater than or equal |
+
+Arithmetics and logic expressions can be arbitrairly combined with the usual rules of associativity and precedence, e.g.,
+
+```
+myMathExpression = 3 + 1 * 2 / 3 - 7
+```
+
+You can also nest expressions in parenthesis:
+
+```
+myMathExpression = 3 + (1 * 2 / (3 - 7))
+```
+
+KCL numbers are implemented using [floating point numbers](https://en.wikipedia.org/wiki/Floating-point_arithmetic). This means that there are occasionally representation and rounding issues, and some oddities such as supporting positive and negative zero.
+
+Some operators can be applied to other types:
+
+- `+` can be used to concatenate strings, e.g., `'hello' + ' ' + 'world!'`
+- Unary `-` can be used with planes or line-like objects such as axes to produce an object with opposite orientation, e.g., `-XY` is a plain which is aligned with `XY` but whose normal aligns with the negative Z axis.
+- The following operators can be used with solids as shorthand for CSG operations:
+  - `+` or `|` for [`union`](/docs/kcl-std/union).
+  - `-` for [`subtract`](/docs/kcl-std/subtract).
+  - `&` for [`intersect`](/docs/kcl-std/intersect)

+Attributes are syntax which affects the language item they annotate. In KCL they are indicated using `@`. For example, `@settings` affects the file in which it appears.
+
+There are two kinds of attributes: named and unnamed attributes. Named attributes (e.g., `@settings`) have a name immediately after the `@` (e.g., `settings`) and affect their surrounding scope. Unnamed attributes have no name and affect the following item, e.g.,
+
+```kcl,norun
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+has an unnamed attribute on the `import` statement.
+
+Named and unnamed attributes may take a parenthesized list of arguments (like a function). Named attributes may also appear without any arguments (e.g., `@no_std`).
+
+## Named attributes
+
+The `@settings` attribute affects the current file and accepts the following arguments: `defaultLengthUnit`, `defaultAngleUnit`, and `kclVersion`. See [settings](/docs/kcl-lang/settings) for details.
+
+The `@no_std` attribute affects the current file, takes no arguments, and causes the standard library to not be implicitly available. It can still be used by being explicitly imported.
+
+## Unnamed attributes
+
+Unnamed attributes may be used on `import` statements when importing non-KCL files. See [projects, modules, and imports](/docs/kcl-lang/modules) for details.
+
+Other unnamed attributes are used on functions inside the standard library, but these are not available in user code.

+
+`import` can also be used to import files from other CAD systems. The format of the statement is the
+same as for KCL files. You can only import the whole file, not items from it. E.g.,
+
+```norun
+import "tests/inputs/cube.obj"
+
+// Use `cube` just like a KCL object.
+```
+
+```kcl
+import "tests/inputs/cube.sldprt" as cube
+
+// Use `cube` just like a KCL object.
+```
+
+For formats lacking unit data (such as STL, OBJ, or PLY files), the default
+unit of measurement is millimeters. Alternatively you may specify the unit
+by using an attribute. Likewise, you can also specify a coordinate system. E.g.,
+
+```kcl
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+When importing a GLTF file, the bin file will be imported as well.
+
+Import paths are relative to the current project directory. Imports currently only work when
+using the native Design Studio, not in the browser.
+
+### Supported values
+
+File formats: `fbx`, `gltf`/`glb`, `obj`+, `ply`+, `sldprt`, `step`/`stp`, `stl`+. (Those marked with a
+'+' support customising the length unit and coordinate system).
+
+Length units: `mm` (the default), `cm`, `m`, `inch`, `ft`, `yd`.
+
+Coordinate systems:
+
+- `zoo` (the default), forward: -Y, up: +Z, handedness: right

+- `vulkan`, forward: +Z, up: -Y, handedness: left

+
+## Performance deep‑dive for foreign‑file imports
+
+Parallelized foreign‑file imports now let you overlap file reads, initialization,
+and rendering. To maximize throughput, you need to understand the three distinct
+stages—reading, initializing (background render start), and invocation (blocking)
+—and structure your code to defer blocking operations until the end.
+
+### Foreign import execution stages
+
+1. **Import (Read / Initialization) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+   ```
+   - Reads the file from disk and makes its API available.
+   - Starts engine rendering but **does not block** your script.
+   - This kick‑starts the render pipeline while you keep executing other code.
+
+2. **Invocation (Blocking) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+
+   cube
+     |> translate(z=10) // ← blocks here only
+   ```
+   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
+
+### Best practices
+
+#### 1. Defer blocking calls
+
+```kcl
+import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
+
+
+// --- perform other operations and calculations here ---
+
+
+cube
+  |> translate(z=10)                        // 2) Blocks only here
+```
+
+#### 2. Split heavy work into separate modules
+
+Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
+
+#### Future improvements
+
+Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.

+
+`KCL` allows splitting code up into multiple files.  Each file is somewhat
+isolated from other files as a separate module.
+
+When you define a function, you can use `export` before it to make it available
+to other modules.
+
+```kcl
+// util.kcl
+export fn increment(@x) {
+  return x + 1
+}
+```
+
+Other files in the project can now import functions that have been exported.
+This makes them available to use in another file.
+
+```norun
+// main.kcl
+import increment from "util.kcl"
+
+answer = increment(41)
+```
+
+Imported files _must_ be in the same project so that units are uniform across
+modules. This means that it must be in the same directory.
+
+Import statements must be at the top-level of a file. It is not allowed to have
+an `import` statement inside a function or in the body of an if‑else.
+
+Multiple functions can be exported in a file.
+
+```kcl
+// util.kcl
+export fn increment(@x) {
+  return x + 1
+}
+
+export fn decrement(@x) {
+  return x - 1
+}
+```
+
+When importing, you can import multiple functions at once.
+
+```norun
+import increment, decrement from "util.kcl"
+```
+
+Imported symbols can be renamed for convenience or to avoid name collisions.
+
+```norun
+import increment as inc, decrement as dec from "util.kcl"
+```
+
+---
+
+## Functions vs `clone`
+
+There are two common patterns for re‑using geometry:
+
+1. **Wrap the construction in a function** – flexible and fully parametric.
+2. **Duplicate an existing object with `clone`** – lightning‑fast, but an exact
+   duplicate.
+
+### Parametric function example
+
+```kcl
+fn cube(center) {
+  return startSketchOn(XY)
+    |> startProfile(at = [center[0] - 10, center[1] - 10])
+    |> line(endAbsolute = [center[0] + 10, center[1] - 10])
+    |> line(endAbsolute = [center[0] + 10, center[1] + 10])
+    |> line(endAbsolute = [center[0] - 10, center[1] + 10])
+    |> close()
+    |> extrude(length = 10)
+}
+
+myCube = cube(center = [0, 0])
+```
+
+*Pros*
+- Any argument can be a parameter – size, position, appearance, etc.
+- Works great inside loops, arrays, or optimisation sweeps.
+
+*Cons*
+- Every invocation rebuilds the entire feature tree.
+- **Slower** than a straight duplicate – each call is its own render job.
+
+### `clone` example
+
+```kcl
+sketch001 = startSketchOn(-XZ)
+  |> circle(center = [0, 0], radius = 10)
+  |> extrude(length = 5) 
+  |> appearance(color = "#ff0000", metalness = 90, roughness = 90)
+
+sketch002 = clone(sketch001)  // ✓ instant copy
+```
+
+*Pros*
+- Roughly an O(1) operation – we just duplicate the underlying engine handle.
+- Perfect when you need ten identical bolts or two copies of the same imported STEP file.
+
+*Cons*
+- **Not parametric** – the clone is exactly the same shape as the source.
+- If you need to tweak dimensions per‑instance, you’re back to a function.
+
+> **Rule of thumb** – Reach for `clone` when the geometry is already what you want. Reach for a function when you need customisation.
+
+---
+
+## Module‑level parallelism
+
+Under the hood, the Design Studio runs **every module in parallel** where it can. This means:
+
+- The top‑level code of `foo.kcl`, `bar.kcl`, and `baz.kcl` all start executing immediately and concurrently.
+- Imports that read foreign files (STEP/OBJ/…) overlap their I/O and background render.
+- CPU‑bound calculations in separate modules get their own worker threads.
+
+### Why modules beat one‑big‑file
+
+If you shoe‑horn everything into `main.kcl`, each statement runs sequentially:
+
+```norun
+import "big.step" as gizmo  // blocks main while reading
+
+gizmo |> translate(x=50)    // blocks again while waiting for render
+```
+
+Split `gizmo` into its own file and the read/render can overlap whatever else `main.kcl` is doing.
+
+```norun
+// gizmo.kcl                   (worker A)
+import "big.step"
+
+// main.kcl                    (worker B)
+import "gizmo.kcl" as gizmo   // non‑blocking
+
+// ... other setup ...
+
+gizmo |> translate(x=50)      // only blocks here
+```
+
+### Gotcha: defining but **not** calling functions
+
+Defining a function inside a module is instantaneous – we just record the byte‑code. The heavy lifting happens when the function is **called**. So:
+
+```norun
+// util.kcl
+export fn makeBolt(size) { /* … expensive CAD … */ }
+```
+
+If `main.kcl` waits until the very end to call `makeBolt`, *none* of that work was parallelised – you’ve pushed the cost back onto the serial tail of your script.
+
+**Better:** call it early or move the invocation into another module.
+
+```norun
+// bolt_instance.kcl
+import makeBolt from "util.kcl"
+bolt = makeBolt(5)  // executed in parallel
+bolt
+```
+
+Now `main.kcl` can `import "bolt_instance.kcl" as bolt` and get the result that was rendered while it was busy doing other things.
+
+---
+
+## Whole module import
+
+You can also import the whole module. This is useful if you want to use the
+result of a module as a variable, like a part.
+
+```norun
+import "tests/inputs/cube.kcl" as cube
+cube
+  |> translate(x=10)
+```
+
+This imports the whole module and makes it available as `cube`. You can then
+use it like any other object. The `cube` variable is now a reference to the
+result of the module. This means that if you change the module, the `cube`
+variable will change as well.
+
+In `cube.kcl`, you cannot have multiple objects. It has to be a single part. If
+you have multiple objects, you will get an error. This is because the module is
+expected to return a single object that can be used as a variable.
+
+The last expression or variable definition becomes the module's return value.
+The module is expected to return a single object that can be used as a variable
+by whatever imports it.
+
+So for example, this is allowed:
+
+```norun
+... a bunch of code to create cube and cube2 ...
+
+myUnion = union([cube, cube2])
+```
+
+You can also do this:
+
+```norun
+... a bunch of code to create cube and cube2 ...
+
+union([cube, cube2])
+```
+
+Either way, the last line will return the union of the two objects.
+
+Or what you could do instead is:
+
+```norun
+... a bunch of code to create cube and cube2 ...
+
+myUnion = union([cube, cube2])
+myUnion
+```
+
+This will assign the union of the two objects to a variable, and then return it
+on the last statement. It's simply another way of doing the same thing.
+
+The final statement is what's important because it's the return value of the
+entire module. The module is expected to return a single object that can be used
+as a variable by the file that imports it.
+
+---
+
+## Multiple instances of the same import
+
+Whether you are importing a file from another CAD system or a KCL file, that
+file represents object(s) in memory. If you import the same file multiple times,
+it will only be rendered once.
+
+If you want to have multiple instances of the same object, you can use the
+[`clone`](/docs/kcl/clone) function. This will render a new instance of the object in memory.
+
+```norun
+import cube from "tests/inputs/cube.kcl"
+
+cube  
+  |> translate(x=10)
+clone(cube)
+  |> translate(x=20)
+```
+
+In the sample above, the `cube` object is imported from a KCL file. The first
+instance is translated 10 units in the x direction. The second instance is
+cloned and translated 20 units in the x direction. The two instances are now
+separate objects in memory, and can be manipulated independently.
+
+Here is an example with a file from another CAD system:
+
+```kcl
+import "tests/inputs/cube.step" as cube
+
+cube
+  |> translate(x=10)
+clone(cube)
+  |> translate(x=20)

+
+Numbers and numeric types in KCL include information about the units of the numbers. So rather than just having a number like `42`, we always have information about the units so we don't confuse 42 mm with 42 inches.
+
+
+## Numeric literals
+
+When writing a number literal, you can use a unit suffix to explicitly state the unit, e.g., `42mm`. The following units are available:
+
+- Length units:
+  - metric: `mm`, `cm`, `m`
+  - imperial: `in`, `ft`, `yd`
+- Angle units: `deg`, `rad`
+- `_` to indicate a unitless number such as a count or ratio.
+
+If you write a numeric literal without a suffix, then the defaults for the current file are used. These defaults are specified using the `@settings` attribute, see [settings](/docs/kcl-lang/settings) for details. Note that if using the defaults, the KCL interpreter won't know whether you intend the number to be a length, angle, or count and will treat it as being possibly any of them.
+
+
+## Numeric types
+
+Just like numbers carry units information, the `number` type also includes units information. Units are written in parentheses after the type, e.g., `number(mm)`.
+
+Any of the suffixes described above can be used meaning that values with that type have the supplied units. E.g., `number(mm)` is the type of number values with mm units and `number(_)` is the type of number values with no units.
+
+You can also use `number(Length)`, `number(Angle)`, or `number(Count)`. These types mean a number with any length, angle, or unitless (count) units, respectively (note that `number(_)` and `number(Count)` are equivalent since there is only one kind of unitless-ness).
+
+Using just `number` means accepting any kind of number, even where the units are unknown by KCL.
+
+
+## Function calls
+
+When calling a function with an argument with numeric type, the declared numeric type in the function signature and the units of the argument value used in the function call must be compatible. Units are adjusted automatically. For example, if a function requires an argument with type `number(mm)`, then you can call it with `2in` and the units will be automatically adjusted, but calling it with `90deg` will cause an error.
+
+
+## Mixing units with arithmetic
+
+When doing arithmetic or comparisons, units will be adjusted as necessary if possible. However, often arithmetic expressions exceed the ability of KCL to accurately choose units which can result in warnings in your code or sometimes errors. In these cases, you will need to give KCL more information. Sometimes this can be done by making units explicit using suffixes. If not, then you will need to use *type ascription*, which asserts that an expression has the supplied type. For example, `(x * y): number(mm)` tells KCL that the units of `x * y` is mm. Note that type ascription does not do any adjustment of the numbers, e.g., `2mm: number(in)` has the value `2in` (note that this would be a very non-idiomatic way to use numeric type ascription, you could simply write `2in`. Usually type ascription is only necessary for supplying type information about the result of computation).
+
+KCL has no support for area, volume, or other higher dimension units. When internal unit tracking requires multiple dimensions, KCL essentially gives up. This is usually where the extra type information described above is needed. If doing computation with higher dimensioned units, you must ensure that all adjustments occur before any computation. E.g., if you want to compute an area with unknown units, you must convert all numbers to the same unit before starting.
+
+
+## Explicit conversions
+
+You might sometimes need to convert from one unit to another for some calculation. You can do this implicitly when calling a function (see above), but if you can't or don't want to, then you can use the explicit conversion functions in the [`std::units`](/docs/kcl-std/modules/std-units) module.

+It can be hard to read repeated function calls, because of all the nested brackets.
+
+```norun
+i = 1
+x = h(g(f(i)))
+```
+
+You can make this easier to read by breaking it into many declarations, but that is a bit annoying.
+
+```norun
+i  = 1
+x0 = f(i)
+x1 = g(x0)
+x  = h(x1)
+```
+
+Instead, you can use the pipeline operator (`|>`) to simplify this.
+
+Basically, `x |> f(%)` is a shorthand for `f(x)`. The left-hand side of the `|>` gets put into
+the `%` in the right-hand side.
+
+So, this means `x |> f(%) |> g(%)` is shorthand for `g(f(x))`. The code example above, with its
+somewhat-clunky `x0` and `x1` constants could be rewritten as
+
+```norun
+i = 1
+x = i
+  |> f(%)
+  |> g(%)
+  |> h(%)
+```
+
+This helps keep your code neat and avoid unnecessary declarations.
+
+## Pipelines and keyword arguments
+
+Say you have a long pipeline of sketch functions, like this:
+
+```norun
+startSketchOn(XZ)
+  |> line(%, end = [3, 4])
+  |> line(%, end = [10, 10])
+  |> line(%, end = [-13, -14])
+  |> close(%)
+```
+
+In this example, each function call outputs a sketch, and it gets put into the next function call via
+the `%`, into the first (unlabeled) argument.
+
+If a function call uses an unlabeled first parameter, it will default to `%` if it's not given. This
+means that `|> line(%, end = [3, 4])` and `|> line(end = [3, 4])` are equivalent! So the above
+could be rewritten as 
+
+```norun
+startSketchOn(XZ)
+ |> line(end = [3, 4])
+ |> line(end = [10, 10])
+ |> line(end = [-13, -14])

+title: "Values and types"
+excerpt: "Documentation of the KCL language for the Zoo Design Studio."
+layout: manual
+---
+
+`KCL` defines the following types and keywords the language.
+
+All these types can be nested in various forms where nesting applies. Like
+arrays can hold objects and vice versa.
+
+## Constant declaration
+
+Constants are defined with a name and a value, like so:
+
+```
+myBool = false
+```
+
+Currently you cannot redeclare a constant.
+
+## Arrays
+
+An array is defined with `[]` braces. What is inside the brackets can
+be of any type. For example, the following is completely valid:
+
+```
+myArray = ["thing", 2, false]
+```
+
+If you want to get a value from an array you can use the index like so:
+`myArray[0]`.
+
+
+## Objects
+
+An object is defined with `{}` braces. Here is an example object:
+
+```
+myObj = { a = 0, b = "thing" }
+```
+
+We support two different ways of getting properties from objects, you can call
+`myObj.a` or `myObj["a"]` both work.
+
+## `ImportedGeometry`
+
+Using `import` you can import geometry defined using other CAD software. In KCL,
+these objects have type `ImportedGeometry` and can mostly be treated like any
+other solid (they can be rotated, scaled, etc.), although there is no access to
+their internal components. See the [modules and imports docs](modules) for more
+detail on importing geometry.
+
+
+## Tags
+
+Tags are used to give a name (tag) to a specific path.
+
+### `TagDeclarator`
+
+The syntax for declaring a tag is `$myTag` you would use it in the following
+way:
+
+```norun
+startSketchOn(XZ)
+  |> startProfile(at = origin)
+  |> angledLine(angle = 0, length = 191.26, tag = $rectangleSegmentA001)
+  |> angledLine(
+       angle = segAng(rectangleSegmentA001) - 90,
+       length = 196.99,
+       tag = $rectangleSegmentB001,
+     )
+  |> angledLine(
+       angle = segAng(rectangleSegmentA001),
+       length = -segLen(rectangleSegmentA001),
+       tag = $rectangleSegmentC001,
+     )
+  |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
+  |> close()
+```
+
+### `TagIdentifier`
+
+As per the example above you can use the tag identifier to get a reference to the 
+tagged object. The syntax for this is `myTag`.
+
+In the example above we use the tag identifier to get the angle of the segment
+`segAng(rectangleSegmentA001)`.
+
+### `Start`
+
+There is a special tag, `START` (with type `Start`, although under the cover, it's a string)
+for identifying the face of a solid which was the start of an extrusion (i.e., the surface which
+is extruded).
+
+### `End`
+
+There is a special tag, `END` (with type `End`, although under the cover, it's a string)
+for identifying the face of a solid which was finishes an extrusion.
+
+### Tag Scope
+
+Tags are scoped globally if in the root context meaning in this example you can 
+use the tag `rectangleSegmentA001` in any function or expression in the file.
+
+However if the code was written like this:
+
+```norun
+fn rect(origin) {
+  return startSketchOn(XZ)
+    |> startProfile(at = origin)
+    |> angledLine(angle = 0, length = 191.26, tag = $rectangleSegmentA001)
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001) - 90,
+         length = 196.99,
+         tag = $rectangleSegmentB001,
+       )
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001),
+         length = -segLen(rectangleSegmentA001),
+         tag = $rectangleSegmentC001,
+       )
+    |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
+    |> close()
+}
+
+rect(origin = [0, 0])
+rect(origin = [20, 0])
+``` 
+
+Those tags would only be available in the `rect` function and not globally.
+
+However you likely want to use those tags somewhere outside the `rect` function.
+
+Tags are accessible through the sketch group they are declared in.
+For example the following code works.
+
+```norun
+fn rect(origin) {
+  return startSketchOn(XZ)
+    |> startProfile(at = origin)
+    |> angledLine(angle = 0, length = 191.26, tag = $rectangleSegmentA001)
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001) - 90,
+         length = 196.99,
+         tag = $rectangleSegmentB001,
+       )
+    |> angledLine(
+         angle = segAng(rectangleSegmentA001),
+         length = -segLen(rectangleSegmentA001),
+         tag = $rectangleSegmentC001,
+       )
+    |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
+    |> close()
+}
+
+rect(origin = [0, 0])
+myRect = rect(origin = [20, 0])
+
+myRect
+  |> extrude(length = 10)
+  |> fillet(radius = 0.5, tags = [myRect.tags.rectangleSegmentA001])
+```
+
+See how we use the tag `rectangleSegmentA001` in the `fillet` function outside
+the `rect` function. This is because the `rect` function is returning the
+sketch group that contains the tags.
+

+please file an issue with the `ast` label on the [modeling-app
+repo](https://github.com/KittyCAD/modeling-app/issues/new).
