I just wanted to show some appreciation and thanks/praise to Emmanuel for creating such a fine 3D tool. SweetHome3D is easily the most efficient 3D floor plan software ever produced. The idea of constructing a 3D floor plan model from a simplified 2D drawing format providing both a 2D SVG and full 3D OBJ model at the same time is genius. There really is no better tool available for this task. Many thanks, and cheers!
