I have been using pattern software for a long time now. I have Pattern Master Boutique, and CADTERNS. PMB boutique is very well supported and the help you get from the company is some of the BEST around! I love the Pattern Editor, it is fantastic. But sadly, I am not too pleased with the Boutique section, I have never got a good fit from it. I have even had a Boutique rep take my measurements, and they were all off, she had my shoulder seam at 6", which is not what my shoulder seam is!! However, I know lots of people who have made wonderful, well fitting garments with this program.

CADTERNS is a sloper generating program, and that is all it does, generates pattern slopers which then have to be manipulated into your desired pattern, so the person has to be have some pattern drafting experience and a CAD software to do the drafting. It's based on 4 measurements (height, bust, waist and hip), and can be refined further by 7 or 8 measurements. This software has been bang on for my body type with just the 4 measurements, and I get a great fit! I have used it for others as well, and it has worked really well.

Just my thoughts on this subject.
