So. Guys, thanks. Ken: I never was able to get the placement of the rotation point (ie: vertex) to jibe with the rotation axis, x,y,or z. Odd things, like a section shooting off seemingly to infinity were happening. I'm nervous of how booleans affect texture consistency. Mark: Success: I made the 45 degree bend with a circle extruded so I could see the effects of my changes. I had success with the 'free' extension envelope, tweeking them all slowly, bit by bit. Did a 'create section' for each end and the corner. Deleted the circles one by one, pasting my shape in and centering it as I did, Looks like a nice clean, sharp object. mdcguamusa: No luck with the torus...turned into a weird object when I took it into the vertex modeller. Took textures poorly. Missed something, I guess. Kieth: Since I never was able to plant the rotation axis on a vertex that worked, no success with your size ratio, which appears to be dead on accurate. (141.43)
