My quick search of something similar didn’t yield anything on the forum, but I have a feeling I’m not the first to ask for it.
I’d like an option for a variable fillet and chamfer to do the maximum up to a selected edge.
(or between two edges). Similar can be found in SolidWorks and Pro-E.
this will speed up workflow.
At least for chamfer, there is a quick workaround with _ChamferEdge and _PushPull.
The chamfer command also has an option to specify a distance once a handle is selected. Unfortunately the chamfer fails.

chamfer-issue.3dm (137.0 KB)
the 2-point distance actually worked for me on the flat, but on the example that I showed, it doesn’t reach the edge.
On the flat? What does that mean?
the right person to address this wish might be @menno
my workaround would be:
…for curves surfaces it will be a ruled surface… for planar and straight edges - a planar surface …
_pointsOn
delete middle row of CV’s
_extendSrf
_extractSrf the top surfaces
delete the unneeded surface
_untrimAll the top surfaces
_createSolid
Yup. Super useful for both fillets and chamfers.
solidworks ?
Pro/E
(Maybe the day Rhino goes parametric I’ll ditch Pro/E but I don’t think it ever will.)
sorry for the vague initial response.
flat straight surfaces worked for the chamfer command with specifying the distance with 2 points.
i.e. when i recreated your example rather than on my part.
Hi Martin -
Thanks. That’s a known issue that’s on the list as RH-82452 ChamferEdge Issue
-wim
@wim … I’m trying to do this chamfer with the two points distance option and it seems @Artur_Tchoukanov can do it but for me it does not work?
In the related RH-21429, Mikko writes “It’s just pure luck that it sometimes works, and usually doesn’t.”.
