The Selma kit for MODO is designed to help with procedural selections. It contains 38 new and re-implemented selection operators to allow you to select elements by: triangles, quads, ngons, vertex count, area, type, length, angle, axis, part/parts, random (including exact count and spaced-out), normal, plane and distance and more.
These are all first-class MODO operators, so appear in the same place as MODO's built-in selection operators.
Versions 1.1 and 1.2 add Select Random Parts, Select N Random Parts, Select Parts by Spacing, Select Vertices by Spacing, Select Non-adjacent Vertices, Select Symmetric, Grow with Pattern, Select Adjacent to Vertices and Select Parts by Area.
Version 1.3 adds Select By Relative Area and reworks a lot of code. Select by Axis concentric mode has been updated.
Version 1.4 adds Select by Mesh, Loops by Length, Loops by Relative Length, Loops by Edge Count, Facing Polygons.
Version 1.5 adds Select Vertices on ColinearEdges, Edges with Coplanar Faces, Edges by Relative Length and Loops to Segments.
Selma is available for MODO 13 and above on Mac, Win32 and Linux platforms.
