CompareVidia Validates Translations of CAD Models
Ensuring Data Integrity

When a CAD model is exported from its original parent CAD system, and then imported into a different CAD/CAM/CMM system, the translation process of that model may introduce unexpected errors. These unexpected errors may range from not all the surfaces transferring over into the new CAD/CAM/CMM system, or the original model surface edges and faces not joining at the appropriate positions in the derivative model.

This can be completed easily before the derivative model is moved downstream into manufacturing, and the part is created.

The CAD validation process is an important part of the ISO standard quality procedures ensuring 3D CAD data integrity and critical to any supply chain quality procedure. CompareVidia provides an extremely accurate, fast and efficient method to compliment your company’s quality process workflows based on the exchange of the 3D CAD data.

Using CompareVidia’s well-documented and traceable quality reporting options like xml, text, ppt or pdf, allow all manufacturing team members full access to the validation information for critical decision-making.

CompareVidia is a specialized application to validate and compare CAD models for translation or design changes. 
A simple workflow enables the user to load two 3D CAD models and compare them each against one another, using pre-defined tolerance criteria. Geometric and Topological shapes are analyzed for errors or changes and models are classified as either PASSED or FAILED. A quality report can be automatically generated to digitally certify compliance with a set criteria by an OEM, including Boeing’s D6-51991 “Quality Assurance Standard for Digital Product Definition” specification.

CompareVidia Pass/Fail
Clear indicators for pass/fail status

For design revision changes, CompareVidia’s TEC module checks for all intended and un-intended design changes in the 3D CAD model. This includes adds, moves or changes to PMI, GD&T or FT&A.

CompareVidia delivers an established benchmark solution to customers looking for efficient and automatic way to validate CAD data model integrity at different stages of digital product life cycle management.

The CompareVidia comparison process is organized in a very intuitive way and strictly driven by user-defined criteria, which specify different levels of comparison.

  • Global check compares volume, surface area and center of mass of the models
  • Local check finds correspondence between the CAD model face structure and measures distance between them
  • Additional checks allows the user to take into account properties of the corresponding entities (such as topology, color, label, layer, etc.)

CompareVidia Provides Precise CAD Data Validation for
Multi-vendor CAD/CAM/Environments

Compare Direction

  • Both Directions
    Projects validation points in both directions from Authority Model onto Check Model and from Check Model onto Authority Model, if distances between all corresponding points are within the tolerance – validation is passed (models are equal)
  • Authority to Check
    Projects validation points from Authority Model onto Check Model, if distances between all corresponding points are within the tolerance – validation is passed. Note: Check Model may contain extra entities not present in the Authority Model, which does not influence the validation result (validation passes).
  • Check to Authority
    Projects validation points from Check Model onto Authority Model, if distances between all corresponding points are within the tolerance – validation is passed. Note: Authority Model can contain extra entities not present in the Check Model which does not influence the validation result (validation passes).
  • Ignore Border Deviation
    Detects tangential deviations along face’s borders and can be used as additional validation criteria. If set to YES it will allow models to PASS even if the border deviation is larger than the set tolerance.
