Where to store user drawing data?

If you want to store user data within an AutoCAD drawing, there are several places you can use:

Integer and real values (numbers) can be stored in the user variables USERI1-USERI5 and USERR1-USERR5 (please note that USERS1-USERS5 values are not stored)
Entity-releated data can be stored in XData records of the individual drawing objects
All types of data (incl. binary) can be saved with a drawing using Dictionaries (XRecords) - this is the right place to store user data
String data can be also stored in the drawing properties (user values)
You can also store data in attributes of an inserted block with a fixed name (not recommended)
Session user data (PC-specific) can be stored in the Windows Registry or in the environment variables

All these places are accessible through VisualLISP, VBA, ARX and .NET.
