Currently the if one wants to avoid printing identical pieces, the workflow looks like this:
- switch to "SIMULATION" and delete identical pattern pieces in the "2D Pattern Window"
- switch back to "PRINT LAYOUT" and run "Nest All Patterns"
- export PLT
- "Undo" a few times (it's actually quite easy to forget how many since you're constantly context-switching)
- cross fingers and hope that you restored everything back to it's original state
It would be nice if one can simply mark some pieces as excluded from printing.
