sa

The sa setting controls the seam allowance. It expects a value in mm or false or 0 to disable seam allowance altogether.

import Brian from "@freesewing/brian";

const pattern = new Brian({
  sa: 10
})

This is ignored if settings.complete is false

Is it though? I suspect this is not clearly enforced and we should clarify that.
