I am having problems with the bevel tool where blender creates unexpected geometry. I have two examples where I don't understand why things are going wrong:
Number 1: I tried to create a revolver cylinder - following this tutorial: https://www.youtube.com/watch?v=RnftMW0Yhzk until about minute 6:32 - and I connected the holes on each side with the bridge edge loop tool. However, when I then tried to bevel the resulting edge around that hole, blender produced uneven and strange geometry.
Now, when I got rid of the faces inside of the loop and extruded faces from the edge loop, the bevel tool worked fine. I checked for unconnected vertices or double vertices on the same spot; and I also made sure all the transformations are applied. But no change, so I am confused as to what the problem is.
Problem 2: I tried to create a sword with a fairly simple geometry. But when trying to bevel one side blender just seems to connect the different vertices in the wrong way, which messes up the geometry.
Just as before, I removed vertices by distance and doublechecked that all vertices and edges are connected. All the transformations are also applied. This model has some ngons but around the side where I want to bevel all the faces are quads; not even sure if that matters. But again, I have no idea what the problem is and would really appreciate if someone could explain what I am doing wrong.
