What's the difference between CAD Model REV-A and REV-B?

Changes that happen during engineering and manufacturing processes are difficult to catch by just overlaying the two parts in a CAD system. That's where the CompareVidia-TEC module fits in. It provides confidence that all differences between Revision "A" model, and Revision "B" are incorporated prior to manufacturing and that saves time, money, and a lot of headaches. The TEC module can be automated using batch mode when you need to check large amounts of data.

The TEC module extends CompareVidia possibilities to track design and engineering changes made to the CAD model. All changes for the 3D CAD model are tracked, including related information like part notes and annotations covering complete 3D MBD (Model Base Definition).

Part Notes & Annotation

TEC checks differences in the PMI (Product Manufacturing Information), GD&T (Geometric Dimensioning & Tolerancing) or FT&A (Functional Tolerancing & Annotation) including extended support of full semantic PMI/GD&T/FT&A representation for Dassault's CATIA V5, Siemens NX, PTC's Creo (ProE) and STEP CAD formats.

TEC also compares and tracks the non-semantic PMI tags that are represented as independent poly-line objects (STEP 203 E2D or IGES). The links between the 3D geometry and its associated graphic information and tolerances are completely upheld. This allows comparison of Model Based Definition (MBD) CAD models side-by-side.

Flexible Reporting

Detecting PMI, GD&T or FT&A differences are included in the CompareVidia report including all geometric, topologic and annotation changes in the CAD model. The report is available as 2D or full 3D format. The 2D report provides simple screen captures, user annotations and notes to give the manufacturing department real-time information before starting the process. The 3D report gives full, detailed information accessible for the operator running TEC.

TEC features an "AUTO-SAVE" feature enables the user to set-up the report structure so it is automatically generated during tracking operation. In many cases, these reports can be added to the QA package for even better clarification of intended and unintended changes in the CAD model. You can select different report formats like: .pdf, .xml, .html.

Batch Comparison

Manually running several CAD models through a validation process can be stressful and time consuming. TEC's "batch compare" feature allows loading the data into the batch process and letting it run automatically. Batch mode comparison operates as an application with its own user interface or can be executed from the command line. TEC's user interface allows on-line monitoring of the process status. And once it's completed, a general report is presented, giving an overview with batch operation results.
