NX8.5 Shell - Preview could not be computed

[blindheim]

Hello,
See attached part file. I'd like to shell the solid. Solid is made by through curves mesh and extrudes + sew. I am able to shell to thickness 0.01 mm, however I'd like to have it shelled to 3 mm. What can I do to be able to do this?

Thank you for your help

I suspect that that it NOT what you really want. I think you need to create two separate models, one for the topof the what looks like a shoe and the sole. You want to have a 3mm wall thickness for the top portion, but not necessarily the sole. I would create two separate models and deal with them separately and then united them at the end.

Thank you.
Tried to make t into more parts, but when I add thickness to just some of the faces some material is added outside some of the other faces, and it is hard to trim this away. Will try some other ways too, but what I actually want to have it 3 mm all over to make a 3D-print, so if there is an easy way to achieve this I would be happy to know.

Thanks

The topology of your model makes any sort of Shell operation thicker than about 0.02mm is simply not going to be work.
