3DM Import for SpaceClaim

3DM Import for SpaceClaim is a Rhinoceros (.3dm) file import add-in for SpaceClaim. This add-in gives SpaceClaim the ability to import polygon mesh data from Rhinoceros/OpenNURBS 3DM files. SpaceClaim already has the ability to import 3DM files. However the 3DM import feature ignores polygon mesh objects in a 3DM file. 3DM Import for SpaceClaim removes this limitation by reading polygon mesh data stored in 3DM files and importing it into SpaceClaim. A polygon mesh in a 3DM file is comprised of a set of triangular or quad faces. 3DM Import for SpaceClaim creates trimmed planar surfaces for each face and knits them together to create a solid. The solid is then cleaned up so that adjacent coplanar faces are merged in single trimmed planar faces.
