Multiple Offset Lisp

Hello to all.

I desperetely need a lisp that can offset different objects at the same time. And and color the offseted objects red if they are fit into each other.

I searched the board but couldnt find anything that i can use. I'll be glad if anyone can help.

Thanks in advance.

I understand the offset multiple (separate) objects but I'm not sure what you mean by color the offseted (sic) objects red if they are fit into each other. Do you mean if they overlap each other? Are you checking for interference amongst 2D objects?

Something like this?

(defun c:mOff (/ ss tmp)
 (vl-load-com)
 (or *moff (setq *moff 10.0))

 (if (setq ss (ssget '((0 . "ARC,CIRCLE,ELLIPSE,*LINE"))))
   (progn
     (initget 6)
     (and (setq tmp (getdist (strcat "\nSpecify Offset <" (vl-princ-to-string *moff) "> : ")))
          (setq *moff tmp))

     (mapcar
       (function
         (lambda (x)
           (vla-offset x *moff)
           (vla-offset x (- *moff))))
       (mapcar 'vlax-ename->vla-object
         (vl-remove-if 'listp
           (mapcar 'cadr (ssnamex ss)))))))
 (princ))

Yes. I want to check if offseted ( ) objects overlap. I need this because the objects has to have a specific space between them. I have to correct them if they arent.

@Lee Mac; Thanks for your lisp but I forgot to mention, i only need outer offset.And i need something (coloring for example) to notice if the objects overlap with each other.

Thank you for making that clear. Looks like Lee Mac has already taken a go at it. Let us know if it meets your requirements.

Try this:

(defun c:mOff (/ ss tmp safe lst)
 (vl-load-com)
 (or *moff (setq *moff 10.0))

 (setq doc (vla-get-ActiveDocument
             (vlax-get-acad-object)))

 (if (setq ss (ssget '((0 . "ARC,CIRCLE,ELLIPSE,*LINE"))))
   (progn
     (initget 6)
     (and (setq tmp (getdist (strcat "\nSpecify Offset <" (vl-princ-to-string *moff) "> : ")))
          (setq *moff tmp))
     (vla-StartUndoMark doc)

     (foreach var (mapcar (function (lambda (x) (vla-offset x *moff)))
                          (mapcar 'vlax-ename->vla-object
                                  (vl-remove-if 'listp (mapcar 'cadr (ssnamex ss)))))
       
       (cond ((<= 0 (vlax-safearray-get-u-bound
                     (setq safe (vlax-variant-value var)) 1))
              (setq lst (cons (vlax-safearray->list safe) lst)))))

     (foreach Obj (setq lst (apply 'append lst))

       (if (vl-some
             (function
               (lambda (x)
                 (vlax-invoke obj 'IntersectWith x acExtendNone)))
             (vl-remove Obj lst))
         (vla-put-color Obj acred)))
     (vla-EndUndoMark doc)))
         
 (princ))

Thank you. Thats what i need.

Happy to have helped

Hi Lee Mac,

Great program. I have a request further for your lisp program if you don't mind.

is it possible the new line after being offset be changed to the current layer?

Thank you, much appreciated

Dear I would like to know if the routine can Preserve only the entity outside and delete the original and the interior?

Hi, 

i used your lisp and is great, i noticed that if i select multiple objets sometimes the offset is going to outsite and sometimes inside, is there a way to chose the way to do the offset, i mean all outside or all inside??

thanks in advance.

Regards!

did you get any answer on this?

dear Lee Mac ,

i add somethings what i need exactly. but its not coming properly some time

(when i will select the line color  "252"  but the offset line i need bylayer) so this will be pipe center line will be one color, pipe will be another color, insulation will be an another color, that is what i need
