Hello, i'm a newbie to using hammer. I'm wondering if there's a way I can make a cutout of a brush (for doorways, holes, ect.)

You'll want to use the Clipping Tool (Shift + X) and drag over what you want to be cut, if one side of the line's red in the 2d view, hit Shift + X again until both are white, and hit enter, a side which is red will be deleted. If used properly a doorway should look something like this, after this just delete the brush where the doorway should be.

Also please never use Carve
