A utility script to weld vertices and clean up smoothing in imported/converted CAD models. Works on Editable_Mesh objects in selection. Does not work on objects with an Edit_Mesh or Edit_Poly modifier applied. I use this to do a first-pass quick cleanup on imported SolidEdge models; it helps eliminate duplicate faces and odd smoothing groups. Can take a long time to run on large meshes (weld verts can be slow), so test on smaller objects at first.
