Ok, so its like this,

I want to cut some circular holes in some brushes, as I want to have some circular pipes running under the ground. I have created the pipes using the Brush > Arbitary Sided command (which I set to 50), but when I try to use the GSC Subtract command Greydiant crashes. The circular brush is solid, not hollowed when I try to do this. So how do I cut the circular holes in brushes if GSC Subtract does not work?

hold shift and left click the wall u want to cut. click the clipper tool (press x) and hold shift and click to make a circle. then press esc and click the wall where u madea circle and press backspace.

HI sicsoaringeagle

I don't understand your answer. After pressing X, what exactly do I click while pressing the Shift Key?, and with which mouse button do I click it with? I have tried every possible variation, but cannot create a circle, let alone cut one out of the brush.

CaesarLike, after you figure out the Clipper tool, download my floor hole example map that I made. Maybe you can get a good idea of what you need to do. The link will die if it isn't accessed for 30 days:

Hi Baratski,

Thanks for the map, but unfortunately Greydiant is unable to open it. God I hate that retarded program!!!!!

Most likely because the example Baratski provided for you is for Call of Duty 2 Radiant. And you are working in CoDUO Radiant.

Thanks LTGHAVOK ,
I thought the map might be from another Cod version.
And yet, I still have no actual answer to my question. At least not one that I can understand.

There is a "cutting windows" tutorial in the CoD2 section. You can use it to cut "kinda circular holes" in your walls in Graydiant.
Instead of making the holes square, cut it a few more times to make it circular.

Hi The_Caretaker,

Thanks for the post. Unfortunately the cod2 tutorial only shows how to make square windows, which I already know how to do.

Yet if cutting holes in brushes is as easy as sicsoaringeagle's post says it is, then why can't anyone tell me how to do this correctly. I have looked through all the video and non-video tutorials, and there is nothing I can find on this. Am I the first person in map making history that has wanted to cut a hole in a brush?? Compared to using gradiant, computer programming is a doddle.

you can't cut an exact circle.. just an almost circle.

if you cut along enough lines like this:

  ___
 /     \
|       |
 \___/

see? alot more "cicular" than a square...
Now.. if you cit along even more line, you get closer and closer to a circle.

Or follow the "arch" tutorial.. you can use that too, come to think of it.. just make the top part twice and use one of them as the "bottom".
