A new CAD related blog has been started by Jim Dowthwaite of Ontario Canada. The blogs name is "Area 31" and it is focused on VB and VBA for AutoCAD and Autodesk Inventor as well as other CAD subject matter.
Welcome to CAD blogging Jim. http://area31.blogspot.com/
Perhaps there needs to be a hip new term for the ever growing list of CAD related blogs like "CADlogs" or "Cabogs". :-)
