Carve vs.
I wanted to make a donut hole for my map. I can do it in carve but I don't want too many brush faces. Any ideas how to make one with Clipping tool?

No need. I just did it with hollow with a negative integer. Still, I would be happy if someone can explain.

You should be able to do that with a 360 degree arch.

EDIT
I might have misread the question.
A donutshaped hole is basicly a round hole with a cylinder in the middle.

1.
Create two cylinders with the brush tool to outline the donut shape. It's important that you don't scale the cylinders after you've made them.

2.
Make a square hole through the floor around the cylinders.

3.
Put in some square brushes that line up with the verticeces on the cylinder and the side of the floor.

4.
Use the clipping tool to cut each of those brushes into the shape of the cylinder.

5.
Copy those brushes and rotate them to make the rest of the donut hole

That does look nice, but how should one place the boxes? I feel that it depends on the exact count of sides in the cylinder.

There should be a box on every side of the cylinder
Here's a picture from a hole with 20 sides instead of 12

You could also use the arch tool, and then use the vertex tool to merge and move the vertices into the square shape. No need for creating a bunch of cubes.

I'd give pictures, but I'm not on a computer with hammer atm

This, and only this. really over-complicating things if you don't use the arch tool.

Yeah, the arch tool might be a better option, but i feel more comfortable using the cylinders to do it.
The end result is pretty much the same though.

Turns out Valve does it this way.
I've looked at some of the Portal 2 maps and when I saw an arch, they filled the gaps with blocks, they didn't use the vertex tool on the arch.

Eugh I write before I think :derp:
They can't use the vertex tool on the arch because of texture differences.
