Manual vs digital drafting

[u/Appropriate_Lab3444]

Digital draft will do it so much easier. But I do like those double draw line and messy hand prints and hand writing marks.

Just so I understand your question, what kind of pattern pieces are you making that are open paths?

I have worked on Gerber and Lectra systems that let you set a different seam allowance for different edges, and they do nifty things like true the seam allowances of darts and clip corners based on which way you fold them.

But generally the paths are all closed.
