I'm designing the below part, and would like to strengthen its inside by adding a honey comb structure. Did not find in SolidWorks 2018 how this should be done.

What I aimed at: make the pattern (below) as sketch, then lift it up as a surface (yes, cutting with itself), then thicken, then cut away the areas within the part I don't want. That workflow does not work.

Since this is such a common need, I'm sure SolidWorks has it covered.

- How would you do this?

- Should I look into the plastics section, but then again metals could also have such structures?

Thanks for any help. This must be a trivial question but with a small search I found nothing that helped. Part of the problem is that "mesh" is an overused term, but I don't know what else to call that? It's not exactly "honeycomb" either, since those are squares.
