Uniform solid scale

[ammed.riveros]

Do you know of any method to be able to scale the solid to the interior uniformly on all its surfaces something like an offset to the interior … ??

Hello…probably something here could help you…

Solid.ThinShell can help here: Dynamo Dictionary

This will simplify things as the offset distance will be consistent. Just make the shell, then use a Solid.Difference between the shell and the original solid to get the stuff in middle.
