MY question is really simple, how the heck do you make this shape in radiant? [this brush was copied from another .map file]

make a brush that is fairly large, and on the top of radiant go to curve>>cylinder, then do the same thing except now do this curve>>cap selection, that cap is that shape

What he said...but this *particular* cap looks like it's been rotated about 30 degrees. Dunno why. Just use a normal cylinder cap as described above.

(Quick note--you have to make the cylinder to get the cap, and you'll get two caps, one on each end, but you can delete the cylinder and the extra cap if that's what you need.)
