So I got a sweet new computer and now I am having some troubles with Civil 3d. I went from a 32-bit windows XP machine wtih 4 gigs of ram and a dual core 2.8 GHz processor with an older radeon graphics card to a 64-bit windows 7 machine with 16 gigs of ram, core i7-2600 (3.4 GHz) quad core processor, and an nvidia quadro 4000 2GB graphics card and I thought my life would be easy. But apparently great hardware will not solve all of my software issues.
When I try to switch to model space from paper space in C3D 2012 (sp1) it hangs for maybe 5 minutes before finally switching over. I have only worked on two drawings with the new machine, but it does it on both. And not everytime, just half the time in one drawing and most of the time in the other. Anyone have any ideas?
This isn't a solution, but just confirmation that I too occasionally have the problem with certain drawings. It's odd, because sometimes I can make the switch just fine in a particular drawing, and other times it will take 5 minutes or more. I have tried purging the drawing and running an audit/repair on it. That doesn't seem to noticeably help.
I was hoping that the service pack would fix it, but it doesn't. Are there any settings that others have noticed affect this problem?
Please set the LAYOUTREGENCTL to 1 this system variable control the regeneration every time that you switch tabs (Model-Layout), and set the WHIPTHREAD to 3 this system variable control your processor operations.
Hope this will help.
Having the same issue. Changing the layoutregenctl improves performance when switching between model and a layout but softwared still hangs when switching between layouts. Had nothing but problems since upgrading to a 64bit computer with plenty of sytem resources....civil3d 2012 is running better on our old crappy 32bit machines!!!!
You may be experiencing the problem that has been reported by users who have shortcuts to network folders in their plotter folder. This causes Autocad to hang or very long regen times when switching layouts.
A simple test is to reset your Autocad profile to default settings which resets the printer directory settings in file options. If that helps then look into this issue on the forums.
It may be a drawing specific issue if the page set up is pointing to certain printers on the network. Again that should clear up if the profile is reset.
Here is a different way to get it done, please take a look at this post:
You can try the proceedure in Tatiana's link. Otherwise simply rename your current profile to something like MyProfile, then restart C3D. Since it won't see the default profile (you renamed it), it will recreate a new default profile. Once you figure out what is wrong with your profile you can fix it and swap it back to be the default.
Didn't work. Any OS settings suggestions as it does not appear to be the AutoCAD profile?....I used the AutoDesk utility(AdMigrator.exe) to reset it and the problem still exists.
