Edit: OK the easiest way I could do it was to create the copings on a straight arc then use Shape bender. Then you might have to adjust with soften/smooth window a little. Copings are made by selecting the top face (or just the outline) of the arc and copying lower down, then use regular push-pull. [image: SXMO_ScreenShot2018-05-29at11.07.16AM.png]
