|
Compute the starting point of the provided line segment.
|
|
|
|
|
|
|
|
```js
|
|
segStart(tag: TagIdentifier) -> [number]
|
|
```
|
|
|
|
|
|
### Arguments
|
|
|
|
| Name | Type | Description | Required |
|
|
|----------|------|-------------|----------|
|
|
| `tag` | [`TagIdentifier`](/docs/kcl/types#tag-identifier) | The line segment being queried by its tag | Yes |
|
|
|
|
### Returns
|
|
|
|
`[number]`
|
|
|
|
|
|
### Examples
|
|
|
|
```js
|
|
w = 15
|
|
cube = startSketchOn('XY')
|
|
|> startProfileAt([0, 0], %)
|
|
|> line(end = [w, 0], tag = $line1)
|
|
|> line(end = [0, w], tag = $line2)
|
|
|> line(end = [-w, 0], tag = $line3)
|
|
|> line(end = [0, -w], tag = $line4)
|
|
|> close()
|
|
|> extrude(length = 5)
|
|
|
|
fn cylinder(radius, tag) {
|
|
return startSketchOn('XY')
|
|
|> startProfileAt([0, 0], %)
|
|
|> circle({
|
|
radius = radius,
|
|
center = segStart(tag)
|
|
}, %)
|
|
|> extrude(length = radius)
|
|
}
|
|
