Selecting Vertices on Symmetry Line of Mirror Modifier

by Ben   Last Updated August 14, 2019 09:15 AM - source

I am trying to extend an existing script that scans meshes for certain conditions, like poles, non-manifold edges and the like.

When a mirror modifier is present on the mesh, all vertices on the symmetry line fall therefore under the conditions non-manifold and 3-valence pole (in case of quad meshes, at any rate).

I want to select the points on that symmetry axis and gather them in an array, to remove them from the other checks' results.

I am uncertain how to best do that, if anybody has suggestions, I would be very grateful for those.
