Hello, I´m trying to use ShrikWrap on a car body without stitching 50 parts to get a solid polysurface. Hooray it works and saves me a lot of time. The mesh is closed and solid. But if I´m checked it with a clipping plane I see the mesh have inner shells inside the walls. How can I remove the shells to get really solid walls? Is there a function to select all mesh faces inside? Or a grasshopper solution for “unhollow”?
Thank you
Carsten
Hello you can surely use SplitDisjointMesh
then select you mesh, invert the selection and delete the other meshes

Hi @Carsten_Glaubitz
If SplitDisjointMesh doesn’t work here, it means that there are surfaces connecting the inner and outer shell somewhere - sort of a small tunnel, probably. You need to locate the hole/bridge between the inner and outer surface, delete a surface loop, run SplitDisjointMesh and then patch up the hole in the outer surface.

Finding the ‘tunnel’ can be very tricky.
You might be able to eliminate this unwanted connection by first offsetting the shrinkwrap outwards and then a second shrinkwrap inwards…

Thanks for all answers.
I solved the problem outside of rhino.
Meshmixer allows to brush-select the outer shell and separate it. After that the inner shell can be deleted.
Stitching all the parts together and setting the inner wall previously took me 2 weeks of work.
So now you can be sloppy and put all the surfaces together loosely, use ShrikWrap and clear it with meshmixer. From zero to a printable model in 5 hours.

Is there a reason the SelBrush command in Rhino would not have worked? Using Extract mesh face and then the SelBrush selector the results might be similiar?
Thank you Scott, I wanna try this.

I used the Mesh > Extract Face command. Then used the Selbrush command within that.
I would be very interested to know if this works for you.
