Hi,

 

I'm looking for an autolisp that can create a rectangular bounding box around a closed object i.e a region, a block of a profile, an open-closed polyline.

 

Thank you in advanced,

 

Nicolas.

Will this work:

 

(defun c:BNDBX (/ eName mn mx)
 (vl-load-com)
 (if (setq eName (car (entsel "\n  >>  Select Object  >> ")))
   (progn
     (vla-getboundingbox (vlax-ename->vla-object eName) 'mn 'mx)
     (vl-cmdf "._rectang" (vlax-safearray->list mn) (vlax-safearray->list mx))))
 (princ))
