Trouble selecting profile

I think I have seen this topic before but I can’t seem to find it. I copied a profile that I have cut fine before. I wanted to make a nest of them. Problem is I can’t seem to select the outer profile. It’s like the profile is broken into all its line segments. And I can’t select them all. Very frustrating. Also is there any way to calculate the linking settings so you can get a tool path to generate in all the holes. Its very frustrating to just fumble around by trial and error until it fits. There doesn’t seem to be rhyme or reason as to what the computer decides it wants to cut. Lol.
