Hello,
i think there should be the option to export a the flat pattern from a sheet metal model as Step or Iges.
In version 2018 there is only the possibility to export as *.sat, *.dxf or *.dwg.
Some of the sheet metal laser systems working with step.
A workaround is to export as *.sat, than import this and after that export it as step.
But i think that is not the right way for a full-size- and full-prize-system.
Best regards
Michael
