How to make this boundary bubble shape easier?

Bubble idea.3dm (4.0 MB)

Is there any way of automating this sort of thing? The idea is for the vertex points to touch the surface itself. Happy to use grasshopper, I’ve experimented with kangaroo and cocoon but I cant seem to get the exact result. Thanks!

you might play a bit with shrinkwrap?
And it is also possible to just build the 3 steps you used.

Thank you, I gave a go with shrinkwrap but i was more looking for a nurbs based approach
Also, it doesn’t pass any continuity checks

OK, then your approach could be that you transfer all methods you used to grasshopper.

Your first two"blocks" import them as breps
deconstruct brep to find “cornerpoints”
sort these points and create interpolated curves.
etcetera.

It will take time to do this one time.
After that you have a parametric version of your “final result”

Try this.
It doesn’t leave you much room for experimenting, but maybe…

What is the name of the second to last component? This is perfect for my needs btw!

It is the Convex Hull 3D, more details about this compoent please visit here…

Thank you very much :slight_smile:
