Good afternoon to everyone! I am a Rhino newbie, and I am trying to join 3 open polysurface rings into one ring (it’s a spare part that I want to 3d print for a drawer). I basically created 3 separate extrusions for my ring, the bottom and top ring are identical and the middle ring is thinner and has a protrusion towards the inner part. I opened up the surfaces where I want all rings to attach to each other (hence I made them purposefully open polysurfaces, but for some reason the join doesn’t work between them.
Thank you in advance for your help! ring.3dm (127.1 KB)
before you can do anything resembling joining. If these did touch exacty (please see Help on object snaps, ‘Osnaps’) or overalp, then in this case a BooleanUnion would do it. But for this, if I understand the goal it is probably easiest to draw the cross section as a polyline and Revolve that.
