Grasshopper cap/dish does not bake

Hi! My first question here.

I am modeling parametric caps on grasshopper, with surfaces of revolution. I have baked a couple of revolved profiles, but one profile does not bake. No messages, just don’t. :face_with_raised_eyebrow:

The green one, like a WWI helmet. What could be the problem?

You have a better chance of a useful answer if you post the file.

Invalid BREP.

Hi Renato
I confirmed your file.
The filleted curve seems to be invalid.
I tested it with Rhino 6, but the result was the same.
I think that it is a bug because I can create srf with Revolution component
when I input a bake curve.

If you created it, you need to do a fillet after creating the srf in Rhino6.
Rhino 6 have Fillet Edge component.

Hi,

Just fit your curve to degree 3. Fillets are degree 2 curve segments. Degree 2 curves tend to not play so nice with these kind of components. A simple fit curve component fixes it.

I’m using Rhino 5. I tried a catenary instead of fillet, just for a test, and it bakes. So, probably it’s a problem with the fillet.

Many thanks

That’s it!!!:ok_hand:

Many thanks.

I came up with a way you could make a surface.:sunglasses:
please see the attached.

what is the best way to generate STL files from these disks? Turn the disk into mesh before?
