Please include detailed documentation such as screenshots, images or video. 1. What product and version are you running? Creo Parametric (7.0.9.0, applies to all versions) 2. What is the problem? I can open this model in an empty simp rep, open the simp rep manager, and create or edit a simp rep--all without loading any 3D CAD. But if I want to get past this screen, my only choices are to Open (saves the simp rep definition and opens it to the graphics window), Cancel (undos any changes I made), or Apply (opens it to the graphics window but does not save the edited simp rep definition). This feels like what was most likely an oversight in the original UI design and was just never properly addressed, I should be able to just press something like "OK" and return to the previous screen without being forced to load all those models. 3. Are you using a workaround? If yes, please describe it. A full workaround is not possible. While you can modify simp reps from the model tree to avoid the dialog window mentioned above, you can only choose default (e.g. Master, Exclude, Automatic, etc.)--not user defined--simp reps this way. 4. What is the use case for your organization? Describe how your idea would work in context or how it would apply to a practical situation. Every designer working with assemblies (which is to say, all users of Creo Parametric) would benefit from being able to modify simp reps without activating them in the graphics window. For large assemblies, this would present massive time savings. 5. What impact does this problem currently have on your organization? (Number of users affected, hours of lost productivity, etc.) In our organization of several hundred Creo Parametric users, everyone spends countless cumulative hours dealing with this issue. I could not accurately put a number on it, but it easily surpasses 1,000 cumulative hours per year across the enterprise spent waiting for Creo to load our massive assemblies, when we don't necessarily need to open the model after making those simp rep definition changes.
