Creo: Erase Models From Session Between Exercises When going through the exercises in a Creo self-guided course or certification, make sure that you not only close the models in Creo when finished with an exercise but also erase them from session memory before moving to the next exercise or question. When you close a model in Creo, while the model itself no longer displays in the graphics window, it's still in Creo's cache, or session memory. Creo employs session memory as a way to shorten open and regeneration time of models. Thus, if you forget to erase models from session memory and the next exercise or question has you open an assembly that has different components of the same name as the previous exercise or question, Creo simply re-opens the model that is still in session memory rather than the model on the harddrive. The net result is either failures or model geometry that does not appear as you expect it to. Example:Exercise 2 has you open an assembly that has a child component named BASE.PRT. You work through E
