Dear All,
I want to store some data in AUTOCAD file. For example, as soon as an AUTOCAD file is opened on any computer, the computer name, date and time must be recorded automatically. When the same file is opened in another computer, the same information must be stored in addition to the earlier information.
Also, this information must be hidden from the users of the file but should be retrievable by me using LISP.
How to do so ?
