I'm having a problem with my model, the edge highlighted with red goes around smoothly as the vertices are rounded off, but the vertices highlighted inside the green circle and all the vertices along its edge are cuspy and the edge seems to stick to them and not go around smoothly.

I want to make the edges smooth around these vertices.

  • $\begingroup$ it looks like you're trying to make an object with some simple planes, I'm not sure it's the best way to do it, but maybe share your file? $\endgroup$ – moonboots Mar 30 at 13:16

  • $\begingroup$ I don't see the same thing when I open the file, it looks round and smooth, there are some problems though, like you need to recalculate normals, to put the Mirror modifier above the Subsurf, also when you'll apply the Mirror you'll probably have to rework your mesh a bit $\endgroup$ – moonboots Mar 30 at 13:50
  • $\begingroup$ Can you show me what you see when you open the file? $\endgroup$ – Yousef Khashaba Mar 30 at 13:54

    $\begingroup$ Oh!! I recaluculated the normals and the problem I was speaking about disappeared! $\endgroup$ – Yousef Khashaba Mar 30 at 13:55

Select everything in Edit mode and recalculate the normals with Ctrl+N. If a face is flipped the modifier won't be able to apply its effect properly.

Ok. I played some with your model. It seems during modeling some edges became corrupt. What you need to do is select all the offending edges, that should be smoothed by SDS but are not, one by one, hit X choose Dissolve Edge, then select the 2 remaining Vertices and hit J. What you will be doing is in fact replacing all erronous existing edges with new ones. Then they become smooth under SDS. Then you can apply Crease to all the needed edges. It's a laborious task, but it works. You need to rebuild all the corrupt edges one by one.

Here I rebuilt 2 edges, as an example.

Edges fixed

  • $\begingroup$ Both edges are creased, but the one I highlighted in red smoothes, and the other one with the vertex inside the green circle is broken edges. $\endgroup$ – Yousef Khashaba Mar 30 at 13:24
  • $\begingroup$ can you upload your .blend file, it would be easier to figure out hands on, you can use this site to upload .blend files; blend-exchange.giantcowfilms.com $\endgroup$ – Aardo Mar 30 at 13:27

  • $\begingroup$ I found a solution, see my answer above $\endgroup$ – Aardo Mar 30 at 14:33
  • $\begingroup$ Actually, Recalculate Normals fixed this issue without having to do the tedious work! Thanks for the tip @moonboots! Thank you anyway @Aardo! $\endgroup$ – Yousef Khashaba Mar 30 at 14:51
