Persistent Display
Creo Parametric supports the persistent display of any field type analysis (curve analysis, surface analysis, or user-defined analysis based on a field point). If you define and save an analysis, the display of this analysis remains on the screen. The analysis display updates with all changes to model geometry.
You can turn the persistent display of any saved analysis off or on by clicking > 
Saved Analysis.
