Variable radius fillet fails

Hello Everyone,

 

Tried a variable radius fillet but the fillet fails.

The disk has a diameter of 600 mm (+- 24") and is 100 mm (+- 4") thick, I tried a 0 mm - 10 mm - 0 mm fillet, but even 1 mm fails.

 

Why is this not possible?

Strange but the other fillet works with the same cut.

 

I'm surely missing something.

 

 

Best regards,

Ludo

Hi Ludo,

 

I feel the problem might be related to how the edge was cut. I’d like to take a close look for the problem. Would it be possible to post the file here or send me via email if you prefer?  

 

You can either Export the entire file as .F3d format or Share Public Link with me by enabling the download permission. Both commands are available under the File menu. My email address: lixiong.xu@autodesk.com

Hello Nicolas,

 

Thanks for your reply.

 

Actually I forgot to add the file Smiley Frustrated.

 

I started a new model with exactly the same dimensions but I cannot reproduce the problem, the fillets perform as expected, so it seems that it's really linked with this file.

Very strange.

 

Thanks for looking at this.

 

Best regards,

Ludo

I think that your original problem is definitely a bug, we will investigate it.  Thanks for providing the model, it helps a lot.

We've confirmed that this is, indeed a bug.  Good catch!  The underlying problem, for those that are interested, has to do with variable radius fillets applied to portions of geometry generated from "periodic" (meaning closed) curves.  In this case, it was a circle, that had been subsequently cut so that you had several pieces remaining of the original circular edge.  Variable fillets on these pieces can show these problems.

 

Anyway, we have a fix for the bug, and we'll get it into production soon.

 

Jeff
