Re: FreeCad, Blender, and SweetHome3D
Thanks for explaining your workflow.

As lengths and coordinates in Sweet Home 3D are internally expressed in centimeters, these values are exported to OBJ format in the same unit. Unfortunately that file format doesn’t specify the unit of the coordinates it contains (DAE format has a unit element to specify that), and that leads to variable interpretations of these numbers according to each software.
If you want to work in meters in Blender, you should scale imported OBJ files exported from Sweet Home 3D to 0.01. If you prefer inches you should scale them to 0,393701.
But isn’t FreeCAD able to directly scale imported OBJ files? That would avoid using Blender just to rescale them.
