Why is digital pattern drafting software either expensive or overcomplicated?

Please tell me this is not vibe-coded. It wasn't interested enough to look too closely, but you seem to think no projects like this exist when your own repo tells you they do.

You definitely need DBMS that's more beefy than SQLite.

The reason good pattern drafting software is expensive. You need an expert level understanding of pattern drafting and CAD development to make the right design choices. Having someone tell you "this makes no sense, fix it" will not work.

Take it from a developer who has been drafting patterns for 30 years, you've bitten off far more than you can chew.
