Hello, I was wondering DraftSight's AutoLisp allowed files to be modified without opening them. My company has their own custom revision and title blocks, and I was hoping that their was a way to update these blocks without having to open each drawing in order to modify it. I found this source from Lee Mac where this feature can be accomplished with AutoCAD. However, it requires an ObjectDBX to interface with the unopened drawings. When I try to run the code to get ObjectDBX, I get an error message.

Therefore, does AutoLisp have ObjectDBX, and is there a way to modify closed drawing in DraftSight?

Mock Code:

AutoLisp
(setq app (vlax-get-acad-object))
(setq vrs (atoi (getvar 'acadver)))
(setq sObjectDBX (if (< vrs 16) "objectdbx.axdbdocument" (strcat "objectdbx.axdbdocument." (itoa vrs)) ))

AutoLisp: Variant 1
(setq dbx (vl-catch-all-apply 'vla-getinterfaceobject (list app sObjectDBX)))
(if (vl-catch-all-error-p dbx)
    (vl-catch-all-error-message dbx)
    dbx
);if

Command Window
Error: Exception occurred..

AutoLisp: Variant 2
(setq dbx (vla-getinterfaceobject app sObjectDBX))

Command Window
*Cancel*
