3DCS Compliant Modeler Brings Real Materials to 3D CAD Models

Compliant Modeler brings dimensional analysis to a new level. As the primary tolerance analysis tool for CATIA version 5 and 6, 3DCS and its add-on Compliant Modeler let the user turn their models into virtual prototypes, accurately reflecting assembly processes, material deformation and composite properties.

This lets the user account for forces and how the specific materials of their product will be affected by the forces, such as gravity, heat, welding, clamping and bending.

This presentation shows an example of adding thermal environment and gravity to the rear bumper of an automobile.
