What Trimmetry does#

Trimmetry takes two splines:

  • Path defines the trajectory and the set of segments;

  • Profile defines the cross-section.

For each Path segment, the plugin builds a sequence of matrices, transforms the Profile points with them, and connects adjacent rings with polygons. Trimming, deformation, UV mapping, and Phong shading are then applied.

Unlike the standard Sweep, Trimmetry is designed for controlled reveals across many segments:

  • GROW reveals the geometry;

  • TRIM cuts away the beginning of the visible range;

  • SPEED_MOD distributes the animation by time or length;

  • OVERLAP sets the overlap between adjacent groups;

  • Segment Sort determines the group order;

  • Anchor Sort determines the point from which each segment is revealed.

Output#

The result is a polygon object. The plugin also creates:

  • a UVW tag with coordinates along the profile and path;

  • a Phong tag with a configurable angle limit;

  • a topologically closed seam at full growth of a closed path when a compatible mode is selected.
