Polygon Shape
This effect replaces the circular cross-section with a regular polygon (triangle through dodecagon) inscribed in the given width and length bounding box. Optional corner radius softens vertices into short arcs. Use it for faceted, prismatic silhouettes. It defines cross-section path geometry only, does not support Growth Curve, and is different from Polygonizer, which can vary N-gon complexity along height.

Parameters
Sides- Number of edges on the regular polygon (3–12, integer).
Width (mm)- Bounding extent on one axis (1–500 mm).
Length (mm)- Bounding extent on the other axis (1–500 mm).
Corner Radius- Rounding at vertices in millimeters (0–200); 0 keeps sharp corners.
Spiral (°)- Rotation of the polygon that increases with height (−1800° to 1800°).
Phase- Angular offset of the polygon around the layer (0–6.28 rad).
How It Works
A regular N-gon is constructed so its extremities fit the width and length you specify, then optional vertex rounding replaces sharp tips with small circular arcs. At each height, that closed polygon is the cross-section; the profile scales it. Phase rotates the polygon in the plane; Spiral adds cumulative twist up the model.
The outline is still a single family of regular polygons unless you change parameters or combine with other tools. For meshes that morph between different side counts from bottom to top, Polygonizer is the dedicated effect.
