Hi Herbert,

> what software do you use for dimensioning?

MoI v3 can now export to DXF format which can then be brought in to various 2D CAD programs, one good one that's free is DraftSight:

If you want to bring the 3D model data over to put dimensions on, either ViaCAD or Rhino can work well for that.
