AutoCAD 2008 compatibility

How compatible is AutoCAD 2008 with the older versions?

OK, the DWG files are compatible - that's important. AutoCAD 2008 still uses the DWG2007 format. It looks like the DWG file format is upgraded every 3rd AutoCAD release so we are safe for one more AutoCAD release (AutoCAD 2009 ?).

As for add-on applications it is more complicated. Generally, AutoCAD 2008 should run the 2007-versions of add-on applications. The 32-bit version of AutoCAD 2008 is binary compatible with AutoCAD 2007. VisualLISP, VBA, ActiveX and most ARX add-ons will probably run unmodified, there may be some problems with their installers.
With the 64-bit version of AutoCAD 2008, it is a different story. The LISP applications should still run fine. For VBA add-ons there is some workaround developed by Autodesk. ActiveX and ObjectARX applications need to be upgraded to work with AutoCAD 2008 64-bit.
