Poster Kaluura gave an excellent demo of ramp building. I've done a lot of complex shapes but I couldn't get the ramp to work and make the edges meet other objects in my scene properly. This demo looks like it will do the trick and I understand most of the steps. I'm actually stuck near the beginning however, because in step 2, he has a nice graphic and says "Extrude without moving. Rotate the extruded loopcut on the Z axis around the 3D cursor."
I can't seem to rotate the extruded face while leaving the original face in place. Can someone more experienced and wiser translate this step for me? Thanks.
