Chamfer at any angle (other than 45) on a solid

Rhino Rhino for Windows

Does anyone know how to create a chamfer on a solid part other than the default 45 degrees (Solid>Fillet Edge>Chamfer Edge)? Or, is this still on the wish-list?

Thanks.

Yes, on the wish list of 10 years, minimum :slight_smile:
Out a version of Rhino every 5 years, I remember … do two calculations…

FWIW, ChamferSrf allows you to pick two distances.

…thanks all.

will this be on the new features list of rhino6 ? I was reading it, but did´t find anything about new options in solidchamfer tool.

Hello - no, ChamferEdge is unchanged in what it can build.

ok. thx for the answer. i was hoping that things like these are happening, i know solid modeling is not rhino´s prior thing, but this one seems to be so easy from a user perspective, and so necessary…

Hi, any chance to get Chamfer Edge by different lenghts / angle ready for Rhino 7? or we have to wait for 8??
I need to do this kind of chamfers almost daily and would be a huge improvement!

Thanks

Hello - this will not be in V7.

ChamferSrf is doing the trick here. thank you guys

this could be in v8. its a shame that there are no options how to chamfer edge besides chamfer distance.

So it is NOT possible to chamfer at other angles than 45?? Is there a workaround?

There is a workaround, which involves using ChamferSrf. That allows you to enter two offset distances for the new chamfer. If you want to chamfer to an angle rather than distances you can use Rhino’s command line calculator to translate the angle into the necessary distances.

For example, say you want a 12mm wide chamfer at 30 degrees. Enter the first distance as 12*sin(30degrees). Enter the second distance as 12*cos(30degrees). Then make sure to pick the two surfaces in the same order as the two distances.

Although you can only chamfer one edge at a time, Rhino remembers the two distances so you only have to enter them for the first edge.

After chamfering you will be left with unwanted parts of the end faces. Select all the chamfers and use them to trim the unwanted bits. You will also need to select all the surfaces and join them to get back to a closed object. Like I say, this is a workaround, it is not a slick operation…

Thanks Jeremy,
Not a great workaround but at least it is something!
Appreciate the tip
cheers!

Is ChamferEdge other than 45deg beyond McNeel boffins coding ability ?

There must be a reason that a non 45deg angle chamfer is not available in Rhino ?

is it not possible to code it ?

do other progs such as Plasticity or Solidworks also fail here ?

My opinion, I’m not McNeel affiliate, but I think the chamfer relays on fillet and fillet works by symmetrical offseting the rails to make the surface.
Changing this would require to rework the whole fillets and this is smtg probably too complex.

18

Indeed, the ChamferEdge, FilletEdge and BlendEdge commands all use the same code paths for creating the intersections prior to fitting straight, circular or G2-continuous surfaces, respectively. It would indeed mean a big rework to do different distances/radii on each surface.

19

Still smtg to put into the wishes because the Fillet/ Blend Alo would be beneficial of this feature.

Something also overdue. Fillets and chamfers (even limited at 45 deg) fail currently in the most extremely basic geometric cases. This work needs serious prioritization IMO.
