Hello- ,you cannot wrap a fillet on an existing one with the same or smaller radius.

Do all the filleting on this part at once if they must all be the same.

as pascal said, fillets generally work fine if you do them correctly in order.

for instance you can’t add a .26 fillet to a .25 corner.

Have to start big and go smaller, can’t start small, then add a big one on top of it it’ll fail 100% of the time.

Yes. I took the shape of what is essentially 3/4" plywood, rounded the interior leg angle and the bottom leg corners @.5". I then want to give a 1/4" round over to the outside face. That’s how I would build it using a router? I don’t understand why this does not work?

Neither do I.

Rhino is probably the only CAD program that can’t deal with making a fillet when it encounters a same size fillet. When two rolling ball fillets run into each other the connecting surface is completely defined. The fact that Rhino developers have no clue how to deal with it is dumbfounding…

If you are willing to make FilletSrf type fillets you can try the script found here

It is designed to make a continuous string of fillets along tangent surfaces and has no problem with same size fillets . In your case since not all the surfaces are tangent it will stop making fillets when it arrives at the sharp corners. Then you will need to extend the fillets and then do all the trimming and joining.

look at what I sent you above

do all your .25 fillets at the same time.

you can’t do a .25 fillet, then do a 2nd .25 fillet on top of it.

fillets have to be done in order of size, biggest to smallest.

Isn’t that what I’ve done? Large fillet (.5") at three points, then .25" fillet along the outside on one side. I am not trying to put a larger fillet over a smaller one.

OK, I double checked. I made the outside bottom leg corner .25" and not .5" like the inside. Changing the outside to .375 and the filleting works. Seriously tho…? A hand router spinning a .25" round over bit can make what I intended. And that is the purpose of me having Rhino, to build the project digitally before I do it in wood.

I don’t make the rules…I just try to make people aware of them.

happy modeling-

What you are doing is telling people how to work around bugs by calling them rules
