I see that there is an interesting application for SolidWorks, for progressive dies. It's Logopress. It exists anything to SolidEdge?
Not familuar with the SW functionality but sounds maybe like EMBOSS?
Sigma nest is one of the popular ones. Our parent company uses us and as a result, we plan to use it as well. An other one that is a step up is Radan, but it's also more $ but can tie into other systems better and is slick. Both are not cheap. The cost is tied to each destination for the files.
I believe there are cheaper ones out there, but they require tons more labor for each export. All of the nesting software costs more than the CAD software.
The EL-cheapo method is to export DXF, and arrange the DXF files on a sheet sketch and re-export.
NX Progressive Die would be your alternative. Here you get the benefit of NX CAM and fefatue based machining, full associativity, etc. You also get FEA based solver for formability, thinning, etc.
Head to head NX will win.
