Brand new to BobCad/Cam and I am trying to use the CAM functionality to produce parts for the Joe's CNC v2.
The first part I am trying to figure out is the left side of the Z axis assembly. I've run into a couple of snags already.

1. First operation I set up is to drill the through holes. My problem seems to be selecting them. It takes a few clicks for each one. Thinking it can't be that hard and I really do know how to use a mouse, I thought I'd ask here if there is some secret handshake method for selecting them.

2. It seems when I get to the large hole/pocket in the middle, the cut generally works up until the very end where the ellipse is, simulation cuts some extra material as if there is something "hidden" that the cam processor is trying to deal with. It's not blatantly obvious, to me anyway, how to examine such a problem much less fix it.

Any pointers would be greatly appreciated.
