Discover your hidden optimization potential

GEOCHECK for Creo is the module for testing and controlling the data quality of CAD models according to the VDA Recommendation 4955/1 of the Association of the German Automotive Industry (VDA).

The certification of GEOCHECK by the VDA guarantees the approval and acceptance of the quality certificate in the whole automotive and supplier industry.

In order to guarantee the interoperability between CAD/CAM systems in downstream processes, the use of test programs for data quality is necessary. This improves design methods and prevents mistakes, respectively aids in repairing mistakes at reasonable cost.

With GEOCHECK, the VDA geometry check module for Creo, the required technical mathematical data quality of the CAD model will be examined and documented step by step during the design process.

GEOCHECK 1.2 was developed in cooperation with BMW and the VDA work group for data quality. The catalogue of test criteria has been expanded to 50 criteria. GEOCHECK meets the VDA-guidelines as well as the guidelines of the European Odette-Specification.

GEOCHECK analyses native Pro/ENGINEER parts and drawings as well as all import models (e.g. Step, Iges, Vdafs, Catia, etc.). In addition to this, it allows the evaluation of models which are processed by other add-on modules, e.g. Sheetmetal.
