      If you are doing a lot of jewelry it would be well worth your time to look into using vertex tools and true bend. It makes it easy to create rings from non symmetric geometry. And you can be as detailed as you need as long as you model cleanly. This required no cleanup after the bend except the removal of the double inner faces at the join. I only used 96 segments but you can easily go to the 200 you were using if need be.

        Hi again,

        Upon closer inspection, although the solidness is good and the profile alignment is good along all of the "straight" section of the rail, using Curviloft, the profile does twist on the shaped part of the rail. Back to TrueBend and solid-fixing. Scaling up x1000 reduced the errors to only 3 ... phew.

        Just thought you might like to know.

          Maybe we can try something...
          Post the file of Profils and Rails in dxf format and let see that Moi3D (nurbs) will made as result in SKP format export...

          ...not sure...of the result πŸ˜„ (it's not your file just a test)

          Here the structure of export SKP

          humhum.jpg

          Reloaded in SU
          more_poly1jpg.jpg

          I must ask more polygons in export! πŸ€“ (rendered as SKP file)

          morepoly.jpg

          This time edges are perfect! (for an SKP file) πŸ˜„

              Next version of Moi (V4) will be more adapted for erase problems of the DXF!

              Another thing : i must reduce the number of Control Points of the curves!
              Or even redraw over it...
              (Whithout change the form of course! )

                OK: reloadable! πŸ˜„

                Just a question : does the section is on the good place or must be placed like that ?
                Or by it's gravity's center ?

                  Looks good pilou.

                  I finally got it done using TrueBend.

                  Thanks.

                      Just for be sure : your dxf was made directly from SketchUP or from another program ?

                          Hi pilou,

                          Yes, it was exported from SU.

                            Thx for the info!

                            Dxf from SketchUp are specific because curves are polylines so numerous "control points" !
                            Maybe Circles and Arcs can be exported as real curves...

                            With this one by Joergberg πŸ€“ (for SU Make)
                            So circles and arcs are not "segmented" ! 😎
                            dxf.jpg

                            As we can see for the circle...that is a true curve!
