Lỗi restoring cached viewports renegerating layout trong autocad năm 2024

I have another issue with this file. I have about 10 tabs with about 25 to 30 viewports and when I switch between tabs to clean up the titleblocks and plot it gets slower and slower. Now I've noticed that the Regenerating modified entities keeps increasing as I switch tabs. Is this causing the problem? Is there a way to stop or change this? Here is the latest I got. It took a full 15 minutes to regenerate the tab.

As a first step, have you tried to switch "Layout Regen Options" (Tools\Options\System) to "Regen when switching layouts"? It might help to narrow down the cause of the problem.

  Re: Caching Viewports... Hi and thanks for the welcom, i can see i will spend allot of time here!

  I have spent hours pulling the drawings apart and have come to the conclusion that it is my annotative scaling that is making the drawing hang. I re-created all my layout tabs and viewports in a brand new drawing, and even got the viewport scaled to 1:50 with my xref loaded. Switching, panning, zooming in the viewport works fine, but the moment i set the annotative scaling to 1:50, it freezes up. This happens in model space and paper space.

  I have existing text and content that i have copied into the drawing, so maybe that is the problem, Either way it is a strange problem to have. None of my other drawings have this problem.

    The xref thing was hanging one of my drawings in the same manner. I just unload the xref's, switched paper/model space and then reload the xrefs.

    Re: Caching Viewports...

    I think you will find that the problem resides in the tempoary file size that handles viewports (\.swp). If you have an ungraceful exit from AutoCAD, it leaves behind allot of junk files. These junk files if left to acumulate over a period of time can drastically reduce your system performance. When AutoCAD exits normally, it deletes these temporary files, but only regarding the current session. any temparary files it encouters from a previous crashed session, are left intact.

    First I suggest you search your system & hidden files for ac$/dmp/err/swp file extensions, without any autodesk product running. Then delete them, and make sure they are gone, by empting the recycle bin. If nothing else I bet your CAD system runs allot quicker. Just a small guide on viewports, is to avoid using too many per sheet. The more viewports, the bigger the swp file required to open. A fairly inocuious & small CAD file with 50+ veiwports will take forever to open, and will probably crash out anyway, while your system tries to create a large swp file. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Showing results for Show only | Search instead for Did you mean:

    Restoring cached viewports? When switching from a paper space tab back to the model tab, Autocad then zooms extents. It says it is "restoring cached viewports". This is new in 2002 and I haven't found a toggle (if there is one) to turn this off. Sorry if this has been posted before, I could not find a "search posts" button to search this discussion group. Thanks.
