Hello there,
I just started learning Grasshopper and Rhino3D and I ran into a bit of an issue.
I wanted to give this vase a thickness using Grasshopper so I downloaded Pufferfish in order to use the Shell node after Capping the holes in the lofted surface.
Now when I used the shell node it was asking for “Removal” which I figured out needs to be a number which then relates to a surface on the model. I tried all surfaces and all of them work properly aside from Nr 7.
When I shell using the top surface (Nr 7) it does not leave me with a closed polysurface yet all the other surfaces work properly.
What can I do to get a closed polysurface after shelling using the top surface for removal?
I included the GH file.
The shell node is all the way to the right and there’s a Data Dam too in case you’re not seeing changes.
Everything is clearly labeled.
why this works?
if you try to “manually offset” your 6 side surfaces -before adding the identical curve on top- here is what you get: self-trimming curves that do not completely cross your offseted surfaces
what happens if you add another curve identycal to the last one, at +0.001 units along Z → everything straightens up because:
outer surfaces end perpendicularly to the surface created with CapHoles
inside surfaces also end perpendicularly to the surfaces created with CapHoles
[edit] silly note
of course you can put this extra section-curve at Z -0.001 as last-but-one item in the list (in such a way to not make your final solid 0.001 units longer than you initially wanted)
Thank you very much!
Since I’m a beginner at Grasshopper and Rhino3D I’ll make sure to go through every node with some panels to figure out exactly what’s going on past the surface level until I truly understand how this works.
