I modeled some furniture in Solid Works, and the only way I found to transfer it to Sweet Home was:

Save the Solid Works model in the .igs extension, then convert this file on the anyconv.com website to .obj

When I import the .obj model into Sweet Home, it comes as a single solid, disregarding drawers, frames, etc... so I can't change the colors and textures of the same piece of furniture.

Considering the models made in Solid Works, what is the best way to transfer them to Sweet Home?
