GeometryQA adds advanced geometry quality verification capabilities to your design engineering process. Using engineering standards defined by the manufacturer, GeometryQA helps eliminate engineering data exchange and interoperation errors caused by geometric problems found in 2D/3D CAD files.

GeometryQA provides the capabilities to automatically check for geometric errors such as tangent continuity of surfaces; minimum curvature radius; slivers, gaps and more. When combined with DesignQA solution for checking overarching design standards or as stand-alone, GeometryQA provides a powerful tool to ensure CAD geometry retains integrity.


Visualisation : GeometryQA provides instant visualisation of geometry errors within the CAD system interface to enable immediate understanding of the extent of any problems.
Out-of-Box Standards : GeometryQA provides instant standards for geometry to ensure and improve data exchange, analysis, class A geometry and manufacturing.
Easily Customisable standards : Each manufacturer can set unique geometry standards for checking with GeometryQA.
Geometry Reporting : Create reports for facilitating correction of problems, for use by management and for acceptance of model quality. GeometryQA will stamp each model with a quality rating, date and time.
Quality Metrics database: Maintain records of geometry standards which pass and fail, plus tools to identify, quantify and track geometry quality across the organisation.This data can be easily visualised using the DriveQA quality metrics management tool from TDCi.
Better manufacturing processes: GeometryQA will check if surfaces have smaller radii than what your manufacturing equipment can produce; ensure that models have correctly defined surface normals for NC toolpath generation; ensure smooth model surfaces critical to automotive and industrial manufacturing; identify and remove gaps and slivers that cause problems in manufacturing equipment.
Improved Data Exchange: GeometryQA will check and identify gaps in curves and between surfaces that can affect interoperability; check for small items of geometry that will be misinterpreted; minimise file size by eradicating duplicate geometry; identify incorrectly translated face geometry caused by overlaps, self intersections etc.
Faster Analysis of Data: GeometryQA will check and verify your data for small faces that can cause suspect analysis results, and will ensure that the model surfaces mesh correctly to give more accurate results.
