CAD problems

Hey guys, I need help
I"m having a problem making holes in an angle that I'm working on in AutoCAD. I have poles set up where I want to create my holes, and I'll click on Subtract, click on my angle, then hit enter, but after I hit enter the commandline says "No solids, surfaces, or regions selected." Any help is much appreciated.
Thanks,
-Marley

Attach the file here.
You must first extrude, revolve (or some other way) create a cylinder first before subtract
or
use Presspull of a circle.

Thank you. I figured out the problem though. For some reason, I had to set the gizmo to no gizmo in order to make the holes.
Thank you though, JD Mather
