Smoothly joining two organic breps

Hello,
Im working on a 3D printed guitar that uses a combination of a generative design structure (imported from another program) and a 3D Vorinoi pattern made in grashopper.

Im trying to join these to organic shapes and ideally have a small radius created where they meet.

Does anyone have any ideas on how to do this? Im relatively new to grashopper

Thanks

Hi!
1 I wonder if you could:

  1. get intersection curves
  2. use item index to find their (as edges) index in the joined mesh
  3. fillet (Though considering the fillet implementation here it would be a tiny radius if any!)

2 Also, would you mind sharing how you got the Voronoi shape going? It looks really good!

3d Vorinoi.gh (19.8 KB)
Yeah here is my .gh file.

and thats a good idea for extracting the intersection curves.

the last part of the file is for joining the parts but its not working yet

And…

Thanks for the link! the multi pipe thread is exactly what i was looking for.

In the photo you posted, did you incorporate the same method towards my design? Its zoomed out enough, I cant see any of the stuff you added.

Thanks so much!

If you have access to the Rhino WIP, you could also use Shrinkwrap for that, but you might lose some precision in the blue part.

I am not sure if it is available in Grasshopper right now, but it’s pretty amazing what it can do, smoothly merging different geometries with that many intersections.

You forgot to internalize the geometry.

Oh gotcha I dident realize you could do that. Im still pretty new to grasshopper.

Thanks so much!

Hmm… I am not sure we are talking about the same thing…

I see that everything is broken since it doesnt have the rhio file. Is there a way to include the geometry in the grashopper file?

Hi Ben -

Yes, that’s the internalization that Quan Li mentioned. Right-click on the input and pick “internalise”.

Hej Ben!
De vill att du skall bifoga geomentri som du hade importerat in frĂĄn Rhino.
Högerklicka på Brep ikonen och välj Internalise data.

Great to know Thank you!
