Legacy Tolerance Analysis Extension (TAE)
The Tolerance Analysis Extension (TAE) is a 1-dimensional tolerance analysis application that was available in earlier releases of Pro/ENGINEER and Creo. Starting with Creo Parametric 4.0 M110, TAE was deprecated in favor of Creo EZ Tolerance Analysis (EZTA), which offers more robust functionality and ease of use over the legacy TAE product.
Before Creo 12.0, Creo EZ Tolerance Analysis included a utility to migrate legacy TAE data to the newer EZTA format.
Starting with Creo Parametric 12.0, the legacy TAE data migration utility has been deprecated, and support for migrating legacy TAE data is no longer available.
Creo EZ Tolerance Analysis now includes a function to clean up a model of any existing legacy TAE data.
If a model contains legacy TAE data, Creo EZ Tolerance Analysis displays a message, informing the user of the presence of TAE data and the possibility that analysis features in the model tree may reference the TAE analysis.
Consider these scenarios:
• If the model contains only the TAE analysis data without any analysis features that reference the TAE data:
◦ Creo EZ Tolerance Analysis automatically deletes the legacy TAE analysis data from the model.
◦ No additional action is required from the user.
• If the model contains TAE analysis data and analysis features that reference the TAE data:
◦ Creo EZ Tolerance Analysis does not automatically delete the analysis features that reference the legacy TAE data.
◦ Legacy TAE analysis features are not regenerated, so any calculated results are likely to become outdated and may not represent the correct results based on the recent geometric or tolerance changes in the model.
◦ Users are encouraged to investigate these features and delete them manually.
