Lee Dunham shares his script for Maya called ld_animToCurve Tool which is a tool that Creates Curves From Moving Objects or Vertices. Check out the ld_animToCurve Tool for Maya Creates Curves From Moving Objects or Vertices here.

Creates a nurbs curve for each selected object and/or vert over a series of frames (like a motionTrail, but without the motionTrail bit).

  • Works using xforms – so object could be constrained or driven by expressions etc.
  • Simple to cleanup – just rebuild the curve,
  • Simple to use – select the objects and/or verts you want execute.

Useful for quickly putting together complex shapes or tracking a vert’s/object’s position.
