So I`ve done next test. Now it`s solid. I`ve done it mostly with sweep and few triangles with network. Curves were rebuilt before surfacing. I`ve trimmed it with ShrinkTrimmedSrf command (just for case). I`ve used also script: /* Highlight naked edges */ var gd = moi.geometryDatabase; gd.deselectAll(); var breps = gd.getObjects().getBreps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getNakedEdges().setProperty( 'selected', true ); Next I`ve joined it into solid.

So I have solid and I can`t bevel that edge. What causes this errors? How to prevent it?



In attachment below you can see what I`ve got after beveling those edge loop above.
