Solid Edge Flat Pattern is not updating, Recompute shows errors

In this scenario, a user is working with a Solid Edge sheet metal part and finds that Flat pattern is not updating after modifications - it still shows the model in the state before changes were made.

Doing a manual Flat Pattern will have no effect.

A "Recompute" shows errors.

Check in PathFinder that you have not rolled back via a "Go To" to a feature which is not the last one.  If so, then all of the features cannot be completely recalculated, resulting in an incorrect Flat Pattern.

To resolve this, do a right click on the last feature, RMB - "Go To" to jump to the end of the PathFinder and recalculate all of the features.

Now go to the "Flatten" feature - the Flat Pattern will update automatically and reflect the changes made to the part.
