I came across this 3D posing program called DesignDoll yesterday that's designed to make to make poses for drawing. It's not a free program ($80 for the license) but you can fiddle around with it in trial mode. Trial mode lacks the ability to export the models to OBJ, loading (you can save in trial mode though) saved files, and the use of the program's community submissions. It's a pretty cool program for those dealing with detailed 2D figures as it is pretty limited as a 3D program, but it gives more than enough for details needed for proportions.
