There are a lot of Visio users out there, and not all of them use Visio in conjuction with AutoCAD. But for those who do; Boy! Do they use AutoCAD!! And when there’s a problem using them in conjunction with each other; Boy! Is there a problem!!
This page will try to bring together as many resources regarding Visio and AutoCAD issues as is humanly possible. I’ll keep updating it as new information comes in, so check back from time to time!
On a positive note, it looks like the AutoCAD compatibility in Visio 2007 is vastly improved! One of the experts on the subject has informed me that beta 2 of Visio 12 has solved many of the issues from previous versions of Visio.
