Geometry Errors
Some errors cannot be detected until the geometry reconstruction process has begun. For example, you could take the following design:
ADD FEATURE PROTRUSION
ADD FEATURE SHELL
OF THICKNESS d10 (to make a cup)
ADD FEATURE PROTRUSION (handle for cup)
and reorder the last two features, which are not dependent on each other. If the geometry of the handle is too thin to be shelled with thickness d10, this creates a geometry error. Creo Parametric fails to regenerate the shell. The failed feature (the shell) is highlighted in red on the model. The RESOLVE FEAT menu appears, and the Failure Diagnostics window opens with information on the failed item.
If you choose Undo Changes, the system undoes the changes in this regeneration and returns to the previous state. In the preceding example, this means that the feature order would be restored.
