Common Issue - Failed features in Creo Parametric

Partner Channel / Creo Parametric

Creo Parametric regenerates a model feature by feature in the order that the features were created and according to the parent/child relationships. Sometimes a problem occurs that causes the regeneration of the model to fail. These are the main reason for why this can happen:

- The geometry is invalid or impossible
- There are references missing between parent/child relationships
- There are models missing in an assembly

This guide describes how to spot these failures and how to interpret the Regeneration manager.

1. Common Issues Failed Features in Creo Parametric Aug 2019

5. Identifying failures by using Regeneration Manager The Regeneration manager can be used to choose which features to regenerate but is also an effective way of identifying failed features or components .

3. Indication of failure Since Creo Parametric 4.0 this is shown by red flags in the activated model: The models Errors and Warnings can be set to different levels by adjusting the configurations in the Notification Center , to modify this settings go to: • File à Options à Notification Center : Note! Some Errors can not be removed such as: Regeneration failed , Missing Model , Import Validation Failure

4. Locating failures Creo alerts by showing a red flag which can be clicked to see what kind of issue it is. In this case the model have a failed round feature The failed parts or features are highlighted in the model tree with bold red text and the children of the failed feature in standard red text. Failed feature Failures in a assembly Part includes a failed feature Part is missing ( missing component ) Assembly includes failed features or objects

6. Working on Failed Models Once the failure is acknowledged you can continue your work with the model. Use the Notification Center to directly solve the models issue by right click and adjust it depending on the issue. It is recommended that you solve the failures by following these steps : Investigate the failed features or components references to each other . Use the tools Edit or Edit Definition to solved the failure. You can also use the command Suppress in order to remove the failed feature/component from the current regeneration, or the option Delete to remove it from the model . Regenerate the model to obtain a successful regeneration. NOTE: We recommend customers with Windchill PDMLink to use ModelCheck in Creo Parametric as a way of controlling the quality of the CAD - data checked in to Windchill PDMLink .
