You will get there, I love designing on this program.

Question. I draw a sheet of plywood 3/4" thick and make it a component.
I want to cut a hole in it. I draw a rectangle on the face of it. then
I push it back 3/4". That doesn't seem to work....

Once you make a component out of the sheet of plywood, you can't add a
hole to it without opening that component. You're just putting
another rectangle on top of your component. Try opening the component
and do the same thing.
