Hallo my friends
I have a problem with creating mesh from surface.
When you created mesh from surface a model is outside geometry. It is completely broken!
It happened to me a second time after the insertion of the substrate DWG. Most of it is okay but I already forgot that this can happen and now I'm finished model and I'm clueless.
I suspect that your model may be very far from the origin. If you move your objects to mesh close to the origin, mesh them and then move them back, it may work better. ----H
