System Information
WIN7 64

Blender Version
2014-04-13 6e9c2d0
2.70.2

Short description of error

Some edges which are connected to beveled edge are not "adjusted"
Im sorry but please see the attached file, I dont know how to describe it clearly.

bevel_issue_edges.blend

Exact steps for others to reproduce the error

Open file (there should be model in edit mode with selected edgloop on corner)
Use bevel tool with multiple segments, Amount around 0.6 (any type)
Look at two unselected edge loops between sharp edges (on flat surface) - 3d cursor is placed here
These "inner" edges overlap the beveled one

Expected behavior

These "inner" edges should fit the bevel curve same as boundary.

Is it this result (the straight yellow lines should have the black shape instead) that you expect?

Yep, looks like these should be bent as well…

willi: yes I would expect these edges curved, thank you

I just fixed a bug related to this (#37502) but this is a different case, where the beveled edges and the crossing edges are not all in the same plane. In that case there was a clear idea of how the curve should go looking only at a local vertex with beveled edges on it.

In the case of this bug, the two beveled edges and two non-beveled edges are all in the same plane. It is not clear what curvature to put on those inner loops. You could say, "look at the adjacent loops and match their curvature" but that works only in some cases (what if the inner corner was really an outer corner - then there'd be conflicting opinions from the neighbors. Also, hate the idea of non-local looking like that.

You could say: in the case exactly like this (two beveled edges forming a "weld", two non-beveled edges joining at the bevel vertex at an angle, all in one plane: use the angle of the non-beveled edges joining as the arc guide. I'm not positive that that is always what people want, however. I have another model example (I call bent_lines) where the outer sides are straight because they are non-manifold: in this case, bending the inner ones looks stranger than making the joins straight.

I don't think there is an easy, "always right", answer here. So for now, I'm going to call the current behavior "as intended". Sorry.
