I'm pretty new to Blender and trying to model various things, but I faced a problem which I can't properly describe to find an answer, so sorry for silly question if it is.
I tried to model several edge bridges like second bottom in a barrel (second bottom edges connect directly to an edge loop on outside wall) and regular edge bridge that connects inside edges to outside wall with a bridge and got strange behavior along connection lines.
I want to 3d print this model thus I'm trying to solidify it and subdivision surface gives these artifacts. I tried to add supporting geometry, the distortion can be reduced but remains there.
I also tried to flip normals, but that has more cosmetic effect to the bottom case bec. it is still smth. wrong with edges but in this case inside.
In case of bridge it makes both edge loops sharp and ugly and I can't apply any bevel etc. to it. In case of second bottom it distorts outer wall. Without all this the model is smooth as expected without any issues.
Any help is much appreciated!
