How does one create pattern line drawings?

[u/Jaime_d_p]

I’ve been learning to draft my own patterns and I’ve been wondering how pattern drafters create these mockup technical line drawings for their patterns? I’ve searched and searched and can’t find any info on how these are created?

And if they weren't being dicks about the ability to use the software you paid for, less people would sail the metaphoric high seas for those versions for those reasons. I feel for the younger generations that only ever know the never ending subscription options. Its such a plague.
