What entities can Skimp import?

Currently, Skimp is designed to import only polygon entities, and their associated materials.

Skimp is intended to be a tool that allows you to bring in high-poly meshes from various file formats into SketchUp.  It is not designed to be a full-fledged file-format conversion tool. 

Items such as poly-lines, layers, cameras, and meta-data are not supported for import using Skimp.
