symetry.py

A helper script for modelling symetric objects

This script finds corresponding vertices of a mesh and copies the shape of left part to right part. Corresponding vertices are found even if coordinates of some vertices are changed. It however does not work if mesh topology is not symetric. If you add or delete vertices or edges, you must do it on both sides symetricaly.

Usage:

  1. start with an object symetric to plane yz, objects created from menu should be OK
  2. move some vertices on the left side, at least 1 face must stay unchanged
  3. run this script (alt-p) and click on "MAKE SYMETRY"

Examples:

After:

The script can also colorize changed vertices:
