Short description of error
When creating a vertex-only bevel via mesh edit or a modifier, the outer edges of the bevel are created as straight lines rather than smooth curves, creating a distorted shape.
Exact steps for others to reproduce the error
Load default scene (File -> New -> [Enter])
RMB -> Cube
3D View -> Properties -> Modifiers Tab -> Add Modifier -> Bevel:
Width: 0.25
Segments: 8
Profile: 0.5
Material: -1
Ticked: Only Vertices
Ticked: Clamp Overlap
Ticked: Loop Slide
This produces a bevel that looks like the first attached image:
The outer edges of the bevel are straight and end in an angle. This is not of any use.
The second attached image gives some idea of what the bevel should look like. The outer edges were created by edge splitting the cube then bevelling the resulting planes, which gives the correct outer shape, but leaves a hole. The mesh in-fill was hand crafted and then spherified.
If the code that is used to bevel the vertices of a 2d plane was used to generate the starting point (the outer edge) of the 3d vertex bevel, I think the results would look much better.
Both blender files are attached:
