+## 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([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)

 stages—reading, initializing (background render start), and invocation (blocking)
 —and structure your code to defer blocking operations until the end.
 
-#### Foreign Import Execution Stages
+### Foreign import execution stages
 
-1. **Import (Read) Stage**  
+1. **Import (Read / Initialization) Stage**
-   ```norun
+   ```kcl
    import "tests/inputs/cube.step" as cube
-   ```  
+   ```
-   - Reads the file from disk and makes its API available.  
+   - Reads the file from disk and makes its API available.
-   - **Does _not_** start Engine rendering or block your script.
+   - Starts engine rendering but **does not block** your script.
+   - This kick‑starts the render pipeline while you keep executing other code.
 
-2. **Initialization (Background Render) Stage**  
+2. **Invocation (Blocking) Stage**
-   ```norun
+   ```kcl
    import "tests/inputs/cube.step" as cube
 
-   myCube = cube    // <- This line starts background rendering
+   cube
-   ```  
+     |> translate(z=10) // ← blocks here only
-   - Invoking the imported symbol (assignment or plain call) triggers Engine rendering _in the background_.  
+   ```
-   - This kick‑starts the render pipeline but doesn’t block—you can continue other work while the Engine processes the model.
+   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
 
-3. **Invocation (Blocking) Stage**  
+### Best practices
-   ```norun
-   import "tests/inputs/cube.step" as cube
 
-   myCube = cube
+#### 1. Defer blocking calls
 
-   myCube
+```kcl
-    |> translate(z=10) // <- This line blocks
+import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
-   ```  
-   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.  
-   - This is the only point where your script will block.
-
-> **Nuance:**  Foreign imports differ from pure KCL modules—calling the same import symbol multiple times (e.g., `screw` twice) starts background rendering twice.
-
-#### Best Practices
-
-##### 1. Defer Blocking Calls
-Initialize early but delay all transformations until after your heavy computation:
-```norun
-import "tests/inputs/cube.step" as cube     // 1) Read
-
-myCube = cube                               // 2) Background render starts
 
 
-// --- perform other operations and calculations or setup here ---
+// --- perform other operations and calculations here ---
 
 
-myCube
-  |> translate(z=10)                        // 3) Blocks only here
-```
-
-##### 2. Encapsulate Imports in Modules
-Keep `main.kcl` free of reads and initialization; wrap them:
-
-```norun
-// imports.kcl
-import "tests/inputs/cube.step" as cube    // Read only
-
-
-export myCube = cube                      // Kick off rendering
-```
-
-```norun
-// main.kcl
-import myCube from "imports.kcl"  // Import the initialized object 
-
-
-// ... computations ...
-
-
-myCube
-  |> translate(z=10)              // Blocking call at the end
-```
-
-##### 3. Avoid Immediate Method Calls
-
-```norun
-import "tests/inputs/cube.step" as cube
-
 cube
-  |> translate(z=10)              // Blocks immediately, negating parallelism
+  |> translate(z=10)                        // 2) Blocks only here
 ```
 
-Both calling methods right on `cube` immediately or leaving an implicit import without assignment introduce blocking.
+#### 2. Split heavy work into separate modules
 
-#### Future Improvements
+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.
