Proprietary face-to-face geometric pattern matching analyzes the whole part definition within the user controlled tolerance. This strategy reliably finds the differences across all precise CAD models without the common failures and false positives of the Boolean approach, or missed areas inherent with the sampling of points approach.
To improve the visual clarity of results users can quickly group similar faces and sets of features together into a single difference or drag and drop them into a user-defined folder in the tree.
Measure the distance between entities, points, and positions and angles between two edges or faces, or 4 positions.
When the models to be compared are in a different orientations (typically for manufacturing setups), an accepted difference can be added to automatically or manually orient them to match.
Comparing only a portion of a file is easily accomplished by hiding the entities to be left out of the comparison.
A special mode for two sets of hierarchical CAD assembly files scans file names and headers and lists side-by-side results. Users can optionally geometrically compare a selected set of parts or launch processes to compare all parts. Quick side-by-side 3D graphical viewing is available to see differences in impacted parts.
Compare semantic differences in Product Manufacturing Information (PMI) including 3D geometric tolerances from these formats:

Report pages for each difference found between the compared models can be automatically generated in seconds. Difference report documents are built in standard SVG files which can be viewed in Chrome, Firefox, Safari, IE, etc. Reports can also be printed and exported to PDF files.
View windows inserted into pages of a report allow paired 3D navigation to quickly get exactly the right zoom and orientation to help the reader understand each difference. Views can be either the Was part or the Is part, or a user-defined transparent overlay of both. An optional integrated Locator view indicates where the view window is on the full model.
Build report templates with background and/or logo images to match company or customer standards and automate the completion of title block information across all report pages.
Add labels, notes, and measurements to pages of your report for added clarity. Connect measurements directly to edges and positions on the 3D model.
