[Radiant Editor]Doors - Cutting out a section from a single Brush?

Just created the sample room for COD. and well, I cloned the room, and now I want to make a door between the two.... cant find any info on making holes in 4 d brushes... That would help me... or if there was some element? do I need to make the wall from 3 different 4d brushes, or is there an easier way to do this?

Found this in the "radiant tutorials" thread:

See if that works :smile:

I am sorry, but I am still a NOOB at this... I have never even thought about mapping before tonight...

I used the door_rotating, pretty cool... does a door type functioning when I Use on it... Im amazed since I dont think this is used in Any MP maps in the actual game... anyways... It still doesnt open a hole in the brush... I will keep triing stuff, but I am gettin frusterated...

Ok, from all of the examples, they start out with complex rooms and not just squares... they seem too use 3 brushes (walls): 1) Left of the door, 2) Right of the door, 3) top of the door

Then they add a door entity in the center... I get the door entity to work, but I was wondering if there was an easy way to start out with a single 4 demension brush (representing a wall) and then simply delete a section of it so that people can walk through it...

UPDATE: Ok, in half-life its called "Clip" function... under selection in Radient there is a clipper, dont know how to use it, or if it will do what I want... lets see!

THE WONDERFUL ANSWER CAME TO ME IN A DREAM!

ITS DSG_SUBTRACT! WOOT!

Thanks for all the help, and just wait for my first map... (if its any good...)
