Thanks!

Boy that wasn't very clear in the first documentation I came to.

So I get that you have to do this Group operation – but why? Seems like an extra step, a waste of effort in the way of getting the job done! can you explain the rationale?

I'm trying to get the hang of the Subtract feature. I draw a rectangle and use the push/pull tool to pull it up into a rectangular solid. I draw a circle and use the push/pull tool to pull it up into a cylinder. I move them so that they overlap, and I select the Subtract Tool. But then, when I point to either of them, the little message pops up and says, "not a solid". What on earth? If these simple extrusions don't count as solids, what does?? Do I have a bad version of the program?

Are those only for paid users??
