ProSTEP iViP Association - CAx Implementor Forum

CAx Implementor Forum

Term

since 1999

Mission

The CAx IF is a joint working group supported by both PDES, Inc. and the ProSTEP iViP Association. The objective of the CAx IF is to advance and accelerate the application reliability of geometric data exchange via ISO STEP 10303. This includes both ensuring a continual increase in the level of quality offered and making new functionality needed by the users available. In addition to the work performed within the framework of the forum, the CAx IF also documents recommendations for implementation in the form of Recommended Practices.

Focus on geometric and dimensional tolerances (GD&T) and long-term archiving

Focus is currently being placed on

Updating the Recommended Practices to include the new edition of ISO 10303 (STEP) AP203 and the third edition of ISO 10303 (STEP) AP214.
New validation properties for the exchange of assemblies as well as the transfer of geometric and dimensional tolerances as visual text fields (“presentation“) in the 3D model.

Work is performed in close cooperation with the LOTAR project group and Maintenance.
