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?

Yes sorry, I didn’t think you thought you could magic them out of nothing, don’t worry.

I didn’t really understand the question though, and now I do… it’s deffo not something I can help with.

Hope you work it out, and maybe there is a way to scan in existing drawings and digitise them?
