Hi Nicholas & moritz, sorry but importing STL files is not likely to be added to MoI anytime soon. The reason is that STL files only contain triangle mesh data, not CAD surfaces are solids like MoI is designed to work with at modeling time.

STL is not really designed to be a format for translating model data between CAD programs, it's meant to be used for transfer to a 3D printer only.
