map a slice and rotate it for a pie

[clankill3r]

I'm looking for a certain topic on mapcore but i cant find it.

It's how to map one slice and then repeat it to make a full circle. It was done for TF2 and it where train depos if i remember correctly.
I hope someone knows what i'm talking about.

Yeah, but I have problems with the aligments, and the topic described the math good if I remember.
