My pattern drafting method (Rundschau: Muller & Sohn) uses a line of a certain length (in this case the shoulder length), starting from a fixed point on one curve and ending on a certain point on another curve. The point can be anywhere on that other curve as long as the length is the length needed. How do I do this in Seamly?
I managed to draw the two curves, and used segment an arc to place the first, non variable, point (A30) on the lower arc. How do I proceed to get a line with a given length to intersect with the curve above it (A31)? Right now, the length isn’t correct and I need a method that will do this every time the pattern will be “graded” with new shoulder length measurements.
Maybe @KarenC can help, as I noticed she has drawn a jacket body using Muller & Sohn?
