I'm not using nesting software yet, we still manually program a punch, plasma, and folding machines from the drawings. But I did do my shopping and found some the limitations of the software that integrates with SE.
Metamation was the clear winner.
Radan also had a decent solution if you are willing to let the export process re-populate your flat patterns within the CAD model. That was the "deal breaker" for me as I'm using those flat patterns to create variables that are displayed in the draft files.
Here were the things that made Metamation top of the list:
1. Direct export from SE to nest software
2. It does it's own folding/unfolding, and has it's own 3D modeling if needed
3. The file name of the exported part can be taken from the "document name formula" feature in SE.
4. The software can be set up for about any punch laser or plasma
5. The software can be tied into management software as the complex systems grow.
6. 5 different methods of nesting avilable.
7. Not outrageously expensive if you are using tools they have programmed before (they have more on file than almost any other player)
