About Us


Computer Aided Design (CAD) and Finite Element Analysis (FEA) software has provided most manufacturing industries with tremendous productivity gains over the past 20 years. The cable industry has not realized these gains, however, because modeling complex helical geometry is difficult using general purpose CAD software. For analysis, expert knowledge is required to define a finite element mesh with appropriate contact and other boundary conditions. CableCAD overcomes these obstacles with specialized cable modeling features that allow you to literally model and analyze your designs in minutes.

The best way to learn about CableCAD's capabilities is to watch our overview presentation. (Adobe Flash Player required.)
