Chamfer along tangencies

[RobbieKnobbie]

It appears adding a chamfer to an edge that goes into a tangent (see attached pic) the chamfer is carried along all tangent edges, even though the SELECT TANGENT CHAINS is not selected.
Am I misinterpreting what this option does, or is this a bug?

Thanks!

Good catch, and thanks for the picture. Two things are going on:

"Select tangent chains" only controls which edges get highlighted when you click. It is on by default for the first treatment on a body, so check the box state before you click.
Even with it off, the CAD kernel itself usually carries a chamfer or fillet along edges that continue smoothly (tangentially) into the one you picked. That is how OpenCascade works, so the option can't fully prevent it.

I'll check whether we can stop the chamfer at the tangent edge, or at least make the label clearer. If you can attach the .lyl file, that would help me reproduce it.

@RobbieKnobbie, I looked into it: the CAD kernel (OpenCascade) always carries a chamfer or fillet on along edges that continue smoothly, so it can't be stopped at the tangent edge. What 1.52.0 changes is that it no longer surprises you: the switch is now called "A click also picks edges that continue smoothly" (that is all it ever decided), and the panel says along how many more edges the kernel will carry the treatment, before you apply it.
