Cannot thicken design "The selected faces could not be offset"

[Anonymous]

This is my first thing i sculpted in fusion, and when i tried to thicken it, it completely failed, no matter what direction or how small the value. Any ideas on what I can do to fix this? thanks.

Imagine you take a small sphere with the diameter of how much you want to thicken it and roll it over the entire surface. Can it touch the surface in every point ? If not, that's one reason it might not work.

Surface curvature is often another reason.

Can you share the model ? (export as .f3d and attach)
