Hello community,
I create model cars in 1/24 scale. I have been looking for a way to create a body with a specific wall thickness (about 1.5mm) from a surface for half an eternity. The surface is a polygon mesh… see screenshots.
What options are there?
Thank you for your help.
Best regards, Dio
Shrinkwrap in Rhino 8 is one of them…
OffsetMesh?
A relatively small offset will likely fail with complex surfaces, when the minimum radius of curvature is close to or smaller than the offset distance (the offset surface intersects itself). ShrinkWrap uses voxels (I think?) so it is a lot more forgiving with complex geometry. However, it will soften detail, so you would want to offset to the side that will not be seen.
hm i believe not, i assume it takes the vertices as a basis and wraps a surface around these though you can inflate the vertices, but that even though it sounds similar might still be different to voxels… but i am just guessing either.
yeah OffsetMesh is not good in rhino… but it can at least be used to establish some start, shrinkwrap can then still come to the rescue 
Try to offset the meshes inwards and then shrinkwrap with a positive offset and a second shrinkwrap with a negative offset.
