Batch processing dwg with ODBX in Autolisp / Visual Lisp for Autocad

ObjectDBX

ObjectDBX allows you to create your own 'ObjectDBX Host Application' a standalone application that can load and manipulate drawings. ObjectDBX is a subset of ObjectARX and a C++ object‐oriented API for manipulating AutoCAD and its related objects, collections, properties, methods. This is perfect for batch processing of dwgs, especially for looking up information. Editing drawings is trickier because it's limited, using accoreconsole.exe is complementary.

- No access to System Variables (getvar ...)

- No Selection sets (ssget ...)

- No ent fonctions (entmod ...)

- No Application Methodes (vla-zoomextents ...)

The function in Autolisp/Visual-Lisp that retrieves the ObjectDBX :

- Argument: String, The complet path of the dwg.

- Return: a VLA object, drawing object

(defun getaxdbdoc (filename / axdbdoc release)
  (setq axdbdoc
     (vlax-create-object
       (if (< (setq release (atoi (getvar "ACADVER"))) 16)
         "ObjectDBX.AxDbDocument"
         (strcat "ObjectDBX.AxDbDocument." (itoa release))
       )
     )
  )
  (if (vl-catch-all-apply 'vla-open (list axdbdoc filename))
    (not (vlax-release-object axdbdoc))
    axdbdoc
  )
)

Principle of use :

Need getdir function in odbx_fct.lsp

(defun c:<foo> (/ axdoc lfil dir)
        ; Choose folder.
    (if (and (setq dir (getdir))
             (setq  lfil (vl-directory-files dir "*.dwg" 1))) 
        (foreach f lfil 
          (if (setq axdoc (getaxdbdoc (strcat dir f)))
            (progn
              ; This is where you do what you want.
              (<dofoo> axdoc)
              ; If you modify the document.
              (vla-saveas axdoc (strcat dir f))
              ; Releases a drawing object
              (vlax-release-object axdoc)
            )
          )
        )
    )
(princ)
)

Dump ObjectDBX

With (vlax-dump-object axdoc t) , you know the applicable properties and methods ObjectDBX.
