Polyline

A path defined by coordinate pairs, optionally closed into a polygon. Use it for squares, triangles, stars, or any custom shape.

Parameters

closed
When checked, the last point connects back to the first, forming a closed polygon. Required for Stack Layers.
absolute / relative
Absolute: x, y from bed center. Relative: point 0 = start; points 1..n = dx, dy from previous point.
Startpoint, point 1, point 2, …
Each point has x and y fields. Use + to add points, − to remove (minimum 2 points).

How it works

Polyline creates a 2D path by connecting the specified points with straight line segments. When closed, the last point connects back to the first. Like all geometry blocks, it produces a flat path at Z = 0 that needs a Z strategy to become 3D.
