Hello,
I have a large Assembly of a machine and I need to simplify the model in 3D sketch, that will be used for MBD Analysis using Motion Simulation. The problem is, I cannot select any of the surface of the objects from my large assembly whenever I try to make a new Datum Plane. What setting should I change, so that I could make certain objects as reference planes? I also would like to know how to make certain objects as reference geometry while I'm sketching.
Thank you in advance!
