EVOLVE Design is Computer-Aided Engineering (CAE) tolerancing software that helps engineers apply correct GD&T (GPS) tolerances to their CAD models.

- Apply functionally and syntactically correct GD&T in a 3D model

- Proof your CAD model’s GD&T and get helpful guidance about changes

- Learn from context-sensitive explanations that refer to the specific section of the standards

- Eliminate waste and errors in manual transcriptions of GD&T




EVOLVE Design proofs your GD&T (GPS) tolerances on the model. It highlights potential tolerancing problems and provides recommendations through its explanatory systems that show relevant guidance based on the GD&T standard chosen.




The EVOLVE Design Tolerance Stackup and Point Generator tools allow for a better understanding of the impact of chosen tolerances.




1. Import CAD and PMI

EVOLVE Design imports various CAD file formats including STEP, IGES, DXF, and QIF. CAD models with PMI information such as GD&T (datums and tolerances) can be imported from QIF (Quality Information Framework*) and STEP 242 files.




2. Define Tolerances

EVOLVE Design allows you to define GD&T (GPS) tolerances according to the chosen standard (ASME Y14.5M – 1994, ASME Y14.5 – 2009, or ISO 1101). The EVOLVE Design Explanatory System reacts to the state changes in the application and always displays relevant information about the current context.




3. Proof GD&T (GPS)

A powerful GD&T (GPS) engine checks the entire model and provides visual notification of tolerance errors and warnings. The issues found are clearly explained and supported by links to the sections of the relevant standards.




4. Generate Report or Save to Project file

After proofing issues are corrected, the changes to GD&T (GPS) can be saved as a report or a project for future reference and can be imported into other EVOLVE products.
