Q - question

How to find in LISP which AutoCAD version has created the DWG file?

A - answer E.g. to find which AutoCAD version has written the MYDRAWING.DWG drawing, use the following code:

(setq f (open "mydrawing.dwg "r"))
(setq li (read-line f))
(setq dwgver (substr li 1 6))
(close f)

Compare the resulting dwgver variable with the version table - see TIP 868.
