The GPL requirements for this case are only when you 'distribute' the
work. I'm assuming you don't expct that people will take your scripts,
build them into the CAD programs, and then 'distribute' them togther. So
long as that is the case, it seems likely that this won't be an issue:
your code is GPL, and you're not 'shipping' their code, or at least not
outside 'mere aggregation' (which doesn't drag in derivative clauses).
So, I can't see any likely problems with this.
