I am in a very small assembly. One fixture plate with two parts mounted to it. I am programming a CNC machine and need to select all the faces you see in this vertical finger shaped notch so I can cut all the faces at once. Window select is the obvious way to do it. Even with the face filter on, the window select does nothing. if I start the window outside the model and bring it in, at least I get a window to appear but it does not collect anything when I let up on the mouse button. It all works fine if I try it in just a model (not an assembly). It is crazy for me to have to select all these faces one by one. Hopefully this is not my only option. Thanks.
