Clipping by gammasts

So... You want to use the clip tool in radiant. Just follow these steps and you can learn how to make your brushes, clipped perfect.                            

     These 2 buttons right here are your clipping tools. Just press it or hit x to activate clipping mode.

    Lets get started clipping. In this tutorial, I will show you how to cut a simple square hole out of a square box.

First, draw a brush that is 192x192x192. Look in the picture if you need help.

To make our first cut, hit the clip button. Next we choose our 2 points to clip at. This is very similar to JK's version of clipping except there is no dragging.

After you get this picture, press Shift+Enter to finish your clip.

Now, deselect all of the brushes.

Select the bigger section and we will make our second clip.

Keep repeating this till you get all 4 cuts done. Select the inner brush.

Press backspace to delete it.

Volia! You have just completed your first clip.

You can use clipping to make doorways, holes, and other things that need to be cut out. One thing not to do with clipping is to make curves. Just use the cylinder for that.
