When you open a drawing "View Only" (with save_display=yes), you see the drawing VERY quickly but cannot change ANYTHING. If this "Saved Display" was converted to a per-view basis instead of the complete drawing (let's call it a "Frozen" drawing view mode), then you could open a Drawing Rep with all views in "Frozen" mode (would open VERY quickly like "View Only" is now). A user could "Resume" a single "Frozen" view to make changes to only it and then switch it back to "Frozen" when done with the view changes. The "Resume" would be just like now when "Resume"-ing an "Erased" view; only the required models are retrieved when "Resume"-ing.
This methodology would make working with large assembly drawings MUCH faster. Currently, you can open a Drawing Rep of "No Views" very quickly and resume/change/erase one view at a time to make changes, which speeds the "making changes" process, but you still have to "Resume" ALL views before saving. That final "Resume" can be VERY time consuming.
If the "Frozen" drawing view mode was made into the standard way of opening drawings, then making changes to large assembly drawings would no longer be the dreaded activity for Creo users. Changes would be made to drawings by un-"Freeze"-ing a view before making changes. Of course, "Update Sheets" and "Update Drawing View" would "Resume" the requested views, update them, and then re-"Freeze" them. This would keep the response time in large assembly drawings much faster except for the unavoidably necessary time when the user specifically asks to "Update" a view or views. When saving a drawing, all "Resumed" views would be set back to "Frozen" so that the "save_display=yes" would properly save the user-expected state of the drawing.
There would have to be a config setting that would allow this functionality to be turned on or off.
One more advantage, that would be an outcome, is that the CADWorker, if it could open drawings "View Only", could generate PDFs very quickly (looking exactly as the user saw them) because NO MODELS would have to be downloaded to the CADWorker; only the drawing file itself.
