CLO3D is software that turns flat pattern pieces into a simulated garment on an avatar. Fit and drape can be judged before any fabric is cut.
A paper pattern gets in through PACX with editable curves. CLO3D also reads DXF, which is the route to take when the pattern comes out of pattern CAD.

Digitize sewing patterns without tracing.
