Can solidworks optimise the cutting of, say, square hollow section lengths, based on its cut list and stock sizes?
No, SOLIDWORKS will not do that. There is third party software for nesting sheet metal parts. I do not know if they would work for structural members.
I had a similar need earlier this year and got a free trial of 1D Cutting Optimizer Software, 1DNest Length Nesting .
It was a bit quirky, but was very fast. Saved me £60 on the first job I used it for which was 5% better than I managed doing it manually.
