My Label is pattern drafting software with a really cool feature. It allows you to customize a 3D model with 47 measurements. As the measurements are entered, the model morphs to reflect each measurement. After all the measurements are entered you can choose a style and see a custom drafted pattern appear on the work table. You can tweak the style measurements (which are based on the model measurements) and then try it on the model. I have had so much fun playing with this virtual fitting room! I can see what styles look good on me without having to stitch them up first! I have made two test garments and I am working on qualifying my measurements - a process of making a muslin and measuring the fit of the muslin in order to tweak the model measurements.
I have a really good fitting pair of pants from my first draft! The beauty is that there is FABULOUS support documentation available. I found this PDF file which taught me about some of the figure variations I had never considered before and how to correct the pant pattern to fit better. If you have ever had trouble fitting pants, give it a read.
