I’ve Only been using the program for 2 days (First time on Bitbucket and in Forums so i hope i have done this right) so it could very well be my error but i cant get a curve that has been segmented to become a pattern piece with the Seam Allowance Tool. It forgets the curve and is a triangle instead. It does not seem to recognize the points in the curve as segments and the curve will only let me select one segment (the entire curve). I have tried to attach my pattern in the files.
I tried a lot of different ways to make it work but nothing would. Really loving the program and its the first big problem i have had with it do far 
Thank you!
