The original is no longer avail, as it was opened with 2013 and saved. Our back up systems only go back a few months and this has been an issue since we upgraded. Attached is the file that was reconstructed in 2011 once these issues started arising...
The precision is interesting... but are the values you are referring to 1 and/or ten millionths of a decimal degree? This is such as extreme amount for any structure. I would imagine that maintaining such precision though the progression of a project would be near impossible while maintaining any real world budget.
Thank you for all your help - we have not encountered the issues like the ones described above in any 2013 created drawings, but only in projects that were already in progress in 2011 once we switched over. 2013 crashes on multiple machines doing varying tasks at extremely intermittent times... Which is why we are switching back to 2011 for our new jobs, but that is a whole other story. The previous provided file was a 2011 file that had been "updated" to 2013 via opening & saving during some working procedures.
I had a look at the file in 2012 and it's fine. I ran some tests with 2013 release and I have good news.
In my beta release of AutoCAD Architecture 2013 SP1 on a virtual system, the file opens up fine, the walls are displayed. It's the same for the file that had already been converted to 2013. So development had already been working on this issue. As I know SP1 should be available soon, so for those of you who are facing this issue, please check out the download side: http://usa.autodesk.com/adsk/servlet/ps/dl/index?siteID=123112&id=2334435&linkID=9240658
In a few days, I can't tell an exact date, sorry for that.
