Hello! Was wondering if anyone has any suggestions on blending these two curves? I want to create a larger fillet on the pink curve and a smaller fillet on the red. Unfortunately I cannot share the file otherwise I would!

Hi Austin - it’s very hard to help without a file. Please post a Rhino file with the objects you are asking about.

Hey Pascal, Here is a version to look at. Thank you!

Hi Austin - I am not following your descrtiption very well - you don’t mean this, do you?

Hey Pascal, Sorry about that. The attached is the direction in which I would like fillets to go. Essentially I want each blend in where they converge.

Hi Austin - something like this then?
Incidentally, you have some overlapping surfaces there along that edge - the vertical cylindrical wall has an extra bit of itself from the edge of the revolved part. In here:

Hey Pascal, essentially yes! This is what I am looking to achieve although with around a g2 continuity if possible. I did not notice the extra surface, was removing that helpful in achieving this result?
Hi Austin - you can use G2 blends where the fillets are but the vertical shape that bends to the cylinder there is not G2
is that also a requirement?
In any case, I’ll outline my steps and you can see of that helps you at all.

Not necessarily a requirement, but not a ton of options otherwise. Thank you so much for your help.
Ah I think I see what you’re saying. Where the vertical transitions in is not G2. Ideally it would be, not sure if that infinitely complicates it though.
Here’s how you can do this, woking at the surface level, rather than as a polysurface.
-
Explode the object and delete this surface:
-
Duplicate and UntrimBorder this surface:
-
Isolate the untrimmed surface and the other two that are involved in that transition:
-
FilletSrf asking for a G2 blend. I used .05 here.
-
FilletSrf at .02:
FilletSrf the last fillet to the large cylindrical surface at .05 to match the first fillet:
(you can delete the large, copied, untrimmed surface now too)
The surfaces being filleted come tangent to one another - so the fillet somewhat loses its way as it approaches the corner it should be hitting:
- Turn on points for the latest fillet - select the end row and SetPt these to the corner
- You can move the next rows vertically just a little to clean up.
That is the hard part - from there you can continue the smaller fillets, surface to surface and then trim out with all the edges of the new fillets.

Thank you so so much! This looks like it will work great, I will try this tonight and update you!
