VertexPlacer
"VertexPlacer 3 is now also a vertex Quantiser (similar to Lightwave Modellers 'Quantise'). It allows you to place a selection of vertices at a specific place on a plane - snap to the nearest given spacing - or snap to the nearest grid point. Vertexplacer works on the vertices of Meshes - Polygons and splines.
Vertexplacer 3 is based on Vertexplacer 2 by Neil Blevins and requires Bslib.ms"
