I was trying to identify where the problems related to CEdge and CFace that SU mentions are placed.
I thank your help, but it seems to requiere a little bit of ruby at first at least.
Ei see Did you use the Cad file as reference or did you copy the edges?
The precision of your units in the Model Info was not set high, and the snap was enabled, meaning this could cause some errors while tracing the CAD
In the 170928_MODEL file I did use the CAD as a reference as well as a start. There are some 3d buildings in the original CAD drawing that we used.
Okay, that’s something to take note off for the next time when I import a CAD.
We did copy the modeled elements to a new drawing. But not one at a time. To check the drawing after paste one by one I can probably start over in the same time
