Using COMPARE command to compare two selection sets

[3dwannab]

Hi all,

 

Not sure if this is even possible to do so before I even attempt to try do you knowledgeable folk know if this can be done via LISP.

 

 - Select first set of objects and choose a base point, save theses objects to drawing A.

 - Do the same for another set of objects, save these objects to drawing B.

 - Open drawing A and run the compare command on drawing B.

Or just keep it inside the drawing. This simple lisp I made Creates a temp block of selection set to a location.

only problem is you have to find a common point between the things you want to check to make sure they overlay properly. (or just move the blocks after)

 

helpful hit I make one selection all one color before running this command.

once done I just delete the temp blocks.

 

;;----------------------------------------------------------------------------;;
;; OVERLAY TO CHECK ALINEMENT
(defun C:OL (/ MP SS BP)
  (setq MP (getpoint "\nCopy To Location: "))
  (while (setq SS (ssget))
    (setq BP (getpoint "\nMove Base Point: "))
    (vl-cmdf "_.Copybase" BP SS "" "_.Pasteblock" MP)
  )
  (princ)
)

Perhaps it's possible to save those two out and run a command line to run a script to run the compare command.
