Hello!
3D printing software uses partial infill https://3dprint.com/82668/infill-shells-3d-printing/

What instruments can we use to do the same in SolidWorks?
It seems useful to know  exact mass distribution and mechanical properties right in SolidWorks.

And it seems that we can export model, process it in an external software or in some SW plugin and reimport back.

Do you know something useful for this purpose?
