How to cut a circle or any shape out of another shape

New to SketchUp and I’m just trying to figure out how to “cut” or subtract a shape from another. Any help would be greatly appreciated.

The exact answer depends upon the exact shapes. Most likely you’ll use Intersect Faces but what you do before that will depend on what you’ve got. Can you share your SKP file showing what you are trying to do?

See this video tutorial and feel free to ask followup questions.
