I’ve seen quite a few complaints that AutoCAD 2009 refuses to open some drawings saved in 2000 or 2004 format unless the Recover command has been used on them. Autodesk has now issued a Knowledge Base item about this issue.
There’s no real fix in AutoCAD 2009 yet, just an external workaround. You will have to fix up the drawings in AutoCAD 2008 or TrueView. Either save the drawings in 2007 format or set the system variable 3DCONVERSIONMODE to 0 and then save them in the old format.
AutoCAD 2009 users, I strongly suggest you go and set the new system variable OPENPARTIAL to 0. Now.
Why? Because if it’s set to the default value of 1, purging can be harmful to your drawings. I’ll fill in the details in a future Bug Watch column, but for now I suggest you just go and fix up that variable. It’s stored in the Registry, so you should only need to do it once unless you use multiple profiles, in which case you should do it once per profile.
If you saw my post or Shaan Hurley’s post about this utility and grabbed it on or before 27 April, please go and grab it again. It’s been updated to fix a couple of bugs.
If you’re an AutoCAD 2008 user you probably already know what the title refers to. If not, you probably don’t need to know. If your drawings are afflicted, I suggest you hop over to Between the Lines, grab the scale list cleanup utility and start cleaning up. Although I’ve found that this utility works very well, paranoia is usually wise in computing so make sure you back up everything before you start! The utility is installed into the AutoCAD 2008 or 2009 main installation folder, and you can make a shortcut to the CleanupScales.exe file on your desktop if you wish to make it easier to fire up.
To the Autodesk people who put the effort into creating this utility, thank you.
Having been very effusive in my praise of AutoCAD 2009’s ViewCube feature, stating among other things that “the ViewCube looks like a finished, polished tool”, I may need to backpedal. Those views, along with all of my 2009 Prequel posts, were based on my experience with the Release Candidate. Although ViewCube was very stable for me in pre-release versions of 2009, I’ve seen severe ViewCube stability problems in the shipping software.
I’ve seen the following problems in just a few minutes use of the ViewCube, on two different PCs:
So, if you are using the shipping version of AutoCAD 2009, I suggest you save all drawings in your session before experimenting with the ViewCube. I would be interested in your experiences with the ViewCube. Is it reliable for you?
…if you’re using Internet Explorer 7. Thanks to Rick for pointing this out. It looks fine in other browsers, including IE6 and my own preferred browser, Firefox 2. Now I have to try to work around the IE7 bugs (which include splitting and misplacing images) to get the blog looking reasonable for everybody. Sigh. Thanks, Microsoft.
Anyway, this means you’ll probably see the layout change around a bit more over the next few days. Do not be alarmed.
