Import/Export STL files (binary or ascii)
- Import automatically remove the doubles.
- Export can export with/without modifiers applied
Issues:
Import:
- Does not handle the normal of the triangles
- Does not handle endien
Export:
- Does not do the object space transformation
- Export only one object (the selected one)
