SigmaUNFOLD

Industry-Leading Unfolding Technology Working for You

Real-World, K-Factor Calculation

SigmaUNFOLD empowers you to recognize sheet metal bend features in a 3D body and flatten the part using accurate K-factor based calculations, which ensures a realistic, real-world representation of the part in the software. Assemblies and parts can be processed individually or simultaneously allowing for complete workflow management.
