I encountered a problem when modeling an inside of the wheel. The problematic part is where a spoke joins a rim. I want both the rim and spoke to have sharp edges, but when I crease the transition between them, the circular shape of the rim is no longer maintained there. And when I don't crease the transition it looks weird. Here is how the creasing looks like without subsurf in edit mode:

If you would like to do some tests on the model, you can download it here. Is there a better way to get sharp edges than via creases? Thank you in advance!

  • $\begingroup$ It seems to me adding a loppcut to inner part of the wheel will be enough to keep it smooth and round in your case. And, of course, several cuts on the external part $\endgroup$ – Mr Zak Aug 19 '15 at 0:12

    $\begingroup$ @MrZak It works well on the inner part! After reading the related post gandalf3 posted, I added loop-cuts on the facing side of the spoke too and merged them where they join rim. It kind of works better, since it gives me a slightly sharper edge of the rim. Probably the easiest solution is just to crease the edges of the spoke and uncrease the transition between the spoke and the rim. Then use loop-cuts on the inner sides (see screenshot). Thanks for the help! :) $\endgroup$ – Matouš Kos Aug 19 '15 at 9:12
  • $\begingroup$ Could edit to include a .blend? (upload to blend-exchange.giantcowfilms.com) Thanks! $\endgroup$ – TARDIS Maker Nov 18 '15 at 17:28
  • $\begingroup$ Have you tried using the Edge Split Modifier instead? $\endgroup$ – Samoth Apr 13 '16 at 13:53

Im not sure if it would help but, you can try separating the inside of the rim by selection and take off the subsurf in the inside of the rim.
