@Alien, That was it! That did the trick, thank you very much I really appreciate the help!

Thanks for the replies everyone. So analyzing the body shows that its a closed solid body. The strange thing is, someone from my company showed me how to do it on the same file, and when they do it, they can select all the edges and each hole on the part, but when I do it, it only allows me to select edges from one face. Everything else is still a closed solid. It's MasterCam 2021 btw. Thanks again for all the help.

So I'm bringing in a SolidWorks model and trying to make all the edges selectable. So I'm using Curve all edges and boxing in and selecting the whole part, but when I End Selection and click the check mark, it only seems to create one edge and none of the holes on the part are selectable. Am I doing something wrong or is there a setting that I might have off? Any help is greatly appreciated. Thanks in advance.

@JParis, I gotcha, well that's easy enough! Thanks for the help!

I know this thread is old, but the title of the post, "Just trying to close a file", is what brought me here. That's exactly want I want to do, just close a file without closing out of MasterCam, but from what I can see, there is no way to do that? Am I missing it? Any replies would be greatly appreciated. Thanks in advance!
