Round walls

it´s easy

circular walls instructions:
1) make a new doodad based off of torch (under props)
2) change its model to that of whatever you want the wall to be
3) place your walls, adjusting the angle by using * and / keys.
4) place ground pathing blockers to make sure that units dont get through

Have fun

I'm not sure about you, but "Round Walls" implies a great number of possibilities.
