is there a way to make cylinder caps in radiant if so i am missing it not like say a telephone poll but caps that are on the outside of the cylinder like a tunnel and the outside caps make a square? right now i am making 2 arches with caps and merging them is htere an easier way?

The caps should be indepented of the cylinder so you should be able to flip them.

I cap my cylinders this way:

Highlight cylinder > Curve > Cap > Cylinder/Dialog (this will cap both ends then delete one end if the player will not see it)

thanks but what i am looking for is well lets say you have a man hole made from a cylinder ok the top part on the street how would cap it so there is an outside cap like an arch has so that there would be a square where the butts up against
