FAQ

Questions?

Which CAD formats and systems does CompareVidia support?

CompareVidia supports major native CAD systems including CATIA, Creo, NX, SolidWorks, Solid Edge, Inventor, and JT, along with neutral formats such as STEP, Parasolid, ACIS, IGES, DXF/DWG, 3D XML, 3D PDF, XCGM, and common mesh formats. 

Why would an OEM use CompareVidia?

 OEMs use CompareVidia to confirm that derivative CAD delivered in the TDP matches the authority model, helping reduce translation risk and improve downstream trust. 

Why would a supplier use CompareVidia?

Suppliers use CompareVidia to verify that incoming revised or translated CAD is accurate before it reaches manufacturing, inspection, or quality workflows. 

What kinds of changes can CompareVidia detect?

CompareVidia can identify intended and unintended differences in model geometry, semantic PMI, GD&T, annotations, notes, and other critical model data. 

How does CompareVidia support compliance workflows?

CompareVidia helps support DPD and audit workflows by generating validation reports that document whether derivative or revised CAD matches required specifications.
