I have a few curves in different orientations, but I’m struggling to nest them on a sheet for laser cutting. I tried experimenting with setPt or projecting to CPlane, but I can’t seem to flatten these curves without distorting/losing their dimensions.

Since not all curves are coplanar ( you can try running the PlanarSrf to check it), you need to first find the closest common plane for each curve and then Orient them to the specified CPlane. For your reference.

The description of the related components above are explained as follow:
ungroup the curves then use *Patch with the asterisk in front that will keep the command in repeat mode, click one curve and hit enter twice, so always click-enter-enter even if there are a bunch you will be finished fairly fast. after that use SelSrf followed by NonmanifoldMerge (that helps you to unroll all at once) then UnrollSrf.
to get the curves for cutting use DupBoarder on the created surfaces, but the surfaces should also export as surfaces so you probably can skip that part, maybe see if the output curves are joined.
