Thanks.... this tutorial was of great help since i always found Filleting the most difficult task.
very well executed....

1:38 "now that I have a radius of 2, any fillet that joins with that should be less than 2"

I find that assumption baffling...Why can't a mating fillet have a larger radius? That and other filleting quirks have resulted in my work flow where I surface model in Rhino, stitch everything together and do parametric filleting in Solid works which is a lot more forgiving, even if the adjacent fillet is greater than 2 :)

Hello- the thing is that Rhino does not know a fillet is a fillet once it is created. So, rolling ball, so to speak, larger than the radius of the existing fillet will create a fillet surface that is self intersecting in Rhino. In feature based applications, fillets are features and when you modify them, they can all be recalculated together. In Rhino, they all need to be done at the same time for those intersections to be resolved. In general, in Rhino, make all the bigger fillets first, then wrap the smaller ones around them.

Thanks so much, it was a great great help!

Hi, can anyone tell how how do you edit a fillet on a model after it has been applied?

Rhino is not a parametric modeling program and you cannot edit the radius of a fillet after creation. You can however extract and untrim surfaces and make a new fillet. Pascal's comment above will also help explain how Rhino is different from parametric modelers.

This just helps me a lot. Thank you so much. :)

I have been trying to use FilletEdge to work on my models, but when I use it, the bevel shows up under the cap and side edge. Clearly I am doing something terribly wrong. Help!

Hi Jeff,

It sounds like there isn't enough space between the surfaces for the fillet to trim and join. In complicated edges that bend back on themselves, it can be useful to try the other rail types like distance between rails and also decrease the radius used. Send in a model noting the edge before and after to tech@mcneel.com if you still need help.

Hi, I've tried to build a 5 sided pyramid using this formula but it didn't all meet up, I took the VA for a pentagon as 108/2. I'll email you the excel sheet I used if could take a look for me? http://www.printman.co.in/cutting-creasing-rule.html

Hi,

Please email the 3dm file before and after the fillets to tech@mcneel.com with an explanation of what's not working please. Myself or one of the other techs will take a look.

I am very new to Rhino and am stumbling through this clumsily. Your demo is simple and I am sure I could do it- but my model won't allow me to select the whole model to analyze to begin with. What am I doing wrong?

Brian James said...

It might be that your model is not joined so the edges aren't seen as areas fillet surfaces can be created. Try the Join command first on all the surfaces you want to fillet. If you still have trouble, please email the file with a description of the issue to tech@mcneel.com
