Making holes

I often find I need to make holes in things - for example, a round hole in a steel plate. I can do it, but it’s a pain in the neck. Can anyone give me any tips to make it easier?

the biggest tip is forethought, the best way is to make the hole first, and then extrude the plate/wall out from it. the other easy way, is boolian operations, I would caution you against them however, because they leave a verry messy mesh.

Thanks, that’s a good tip. I’ve always tried to do it the other way. I’ll try that.
