Are you still looking for a way to extract attributes from your drawings into an Excel file?
If so, thanks to alot of hard work on the part of some people at VBA design forum and a lot of headaches and sweating blood I have an Excel macro program that works on what seems to be from R14 through 2004. It's written in VBA and run from Excel accessing your choice of drawings a single drawing or a complete folder. Depending on your needs it will need to be modified but should work. Let me know if interested, I know what it's like to need something like this.
