Hey guys, I have to create a lot of 5cm panels from the surface offset which works now like a charm through @Willem s tip with offset mesh.
1 question remaining is if there is a quick way to select to surfaces and make a solid (in my case a foam panel 5cm) out of them.
@hannesgrebin - just to take it a little further, since it seemed at least possible, here’s one that will attempt to match up pairs of surfaces if you select them all at once.
