I want to create an object with one tube plus another half like in the screenshot but as you can see there is intersecting polygons.

I have tried connect objects, connect and bool but none solves my problem. What is the best way to create the form I'm looking for?

  • Ive never used Cinema4D (Lite doesn't really function well for me and don't own the pro) but probably need to combine the flat ones and then extrude them. In AutoCAD this would be combining Polylines and then Extruding but not sure what its called in Cinema4D – Ryan Mar 4 '16 at 17:52
  • Doing Boolean operations on pure polygonal data will just give you grief. There's no way for it to work well it can only work adequately. – joojaa Mar 4 '16 at 18:03

option 1:

  • create 2 tubes and cut anything you want to cut from the second tube

enter image description here

  • select both tubes > rmb > connect obejcts and delete

enter image description here

  • select common edges

enter image description here

  • rmb > stitch and sew

enter image description here

  • while holding CTRL drag from one point to another

enter image description here

  • do the same on another side

  • select some polygons and hide them to see "the wall" between tubes

enter image description here

enter image description here

  • delete the wall

  • unhide polygons

  • profit

option 2:

  • create 2 tubes and cut anything you want to cut from the second tube

  • select contour edges on half-ring

enter image description here

  • mesh > commands > edge to spline

enter image description here

  • select ONLY outside edges on the other ring

  • mesh > commands > edge to spline

  • select both splines

  • create a "spline mask"

  • put both splines into the mask

  • in the mask options choose XZ (along Y)

enter image description here

  • press C

  • select the inner edge of the ring > egde to spline

  • select both splines > rmb > connect objects and delete

  • create an extrusion

  • profit
