Hello there! I am trying to get some results with filletings having variable radius but I still did not understand the logic behind the process. There are very few videos in the web related to the topic. Are there any other learning resources about it? For example, how do we achieve a filleting on a straight corner line -say on a cube- which begins with a large radius and ends in a narrow one? If someone puts some visual explanation it will be appreciated highly, really.

Thanks in advance for any help!

Easy even a little tricky because the new variable fillet radius are "input after" but always inside the same calling of the function Fillet!!!

Select edge(s) : input general Radius (here 3)
don't exit the function!!! So don't press Done or Right Click!!!

Call New Point Set (any time you want inside the same function)
Point one or several Points on this same edge(s) : input new Radius (here only the Point right corner + Radius =0 )
You can Press Done or Right Click for the new Input Radius

Final Done (or Right Click) or Input another set of new point(s) on this same Edges!

Have fun fillteting!
(on the video following you don't see the click "0" on the calculator due the compression of the reccording but it's writed on the board! ;)



Here following 3 Edges in the same time!
General Radius = 3
One set of Points clicked on the midle of each 3 Edges : Radius =2
(of course if same corners like above wanted just input Radius =0 on a second set of Points !
So just one click because it's the same corner of 3 edges!) So your 3 Edges will have 3, 2 & 0 as Fillets ;)

If you want more numerous complex Fillets on this 3 sames edges input new Set of Points any times you want!
You can click anywhere you want on these 3 edges!

Don't be afraid if previous fillets disapear when you call a new set of points!
It's normal for that you can point anywhere new points on the original edges!



When the final Done is made no possibility to remake new fillets on these original edges!
You must make Undo if you are just after the fillet function else it's not trivial to erase a Fillet! ;)

A little training is necessary the first times you make a variable fillet but it's very easy when you have undertood these simple steps!
- Select edge(s)
- One General Radius
- Particular Radius on these selected edges by new Set of points but always during the same calling of the function !!!

Of course you can retake this same volume filleted for new variable fillets on another edges!

PS Will be the same with curves of volumes (just careful to the admissibility of the radius!!! )

Pilou and Karsten thanks both... your answers are very helpful! It would be good for the tool having some actual visual guides-appearing during the process on the edges to be filleted- but, anyway, will experiment with it. If I meet difficulties will ask again... : - )
