I have this part of a model that doesn't have as much geometry as I want.

I tried to use Subdivision modifier but I got this instead:

I want to be able to not see any edges when printing. I'm also open to use any other program if needed.

  • $\begingroup$ That object appears to be made from tris rather than quads which the subdiv modifier doesn't like. What software was used to create it? $\endgroup$

    $\begingroup$ Not really, The topology is a complete mess. Starting again from scratch using Blender would be the way to go. $\endgroup$

  • $\begingroup$ I honestly can't tell exactly how someone might have modeled something so simple and mad it that big of a mess :P $\endgroup$

  • $\begingroup$ i think they ripped it from the game and did minimum fixing. it looks fine when printed its just pretty lowpoly $\endgroup$

It must be modelled in another software. Maybe that's conversion from solid to surface model and that's why the geometry is a mess making it difficult to work with. It will definitely be a lot easier and precise to model it from scratch than to attempt to fix it, but you could go to edit mode(tab), select the edges you want sharp ctrl+clicking to select shortest path and then crease them(shift+e -> 1) to make them sharp during subdivision.

  • $\begingroup$ yeah that diddnt work very well but thanks anyway! i'll just model it from scratch $\endgroup$

  • $\begingroup$ Well... What exactly did you expect then? Seems to work pretty well... i.imgur.com/KVHJFGN.png $\endgroup$ Aug 22, 2022 at 16:15
