CONTOUR
The outline round elements' closed shapes, a distance out: a contour cut, or a weed border that follows a design.
Syntax
CONTOUR(distance, @a, …)
| Argument | Meaning |
|---|---|
| distance | How far out from the shapes (0: on them). |
| @a, … | Elements: each an id (@5) or a list of them ({@5,@6}), as many as you like. |
Result
A list of outlines, each a list of positions (a closed polygon): the shapes grown by the distance, rounded at their corners and joined where they come within twice the distance of each other.
Examples
In the example drawing:
| Expression | Gives |
|---|---|
CONTOUR(5,@6).COUNT |
1 |
Notes
The Contour Cut Tool and the Weed Border Tool (an outline round the shapes) draw each outline as a closed polyline in a block, so it follows the design.
