Hi,

Most probably I will start working soon on a multi-floor implementation for our software based on SweetHome3D. I suppose we will support floor with planar base and a fixed height. Up to now I've implemented multi-connected walls, realtime roof generator, geometry features on the walls (holes, carvings etc). Also some very big enhancements of the GUI - Substance theme, Flamingo ribbon and docking. If someone is interested in these things, please contact me at svr<at>start.bg.

Regards!
