Addition of multiple polyline

[William.Gares]

Is there a way to highlight multiple polylines in a drawing and find the total length?

Well, technically the ._DataExtraction command can do it, but that involves a lot of work to get there.
You might want to head over to http://www.turvill.com/t2/free_stuff/index.htm and download TLEN.LSP.
If you are not sure what to do with autolisp code, see http://www.cadtutor.net/faq/question...ISP+routine%3F

[William.Gares]

hmm, downloaded it and got an error when trying it.

[rkmcswain]

What did the error say?

[William.Gares]

After selecting the objects and hitting enter it said " ; error: Function cancelled "

In the event you cannot get TLEN.lsp working, here's a small substitute:

(defun c:FOO  (/ ss)
  (vl-load-com)
  (prompt "\n  >>  Select Multiple Polylines for Total Length: ")
  (if (setq ss (ssget '((0 . "*POLYLINE"))))
    ((lambda (i / e l)
       (while (setq e (ssname ss (setq i (1+ i))))
         (setq l
                 (+ (cond (l)
                          ((setq l 0)))
                    (vla-get-length 
                      (vlax-ename->vla-object e)))))
       (prompt (strcat "\n  >>  Total Length = " (rtos l 2 2))))
      -1)
    (prompt "\n  <!>  Nothing Selected  <!> "))
  (princ))

Hope this helps!

The FOO command didn't work either when loaded.

I appreciate the help though.

[rkmcswain]

Something is wrong then, because I've used TLEN many times, and I just tried FOO and it works fine also.

Are you getting an error when you load the file?

[William.Gares]

The file seems to load fine. Does the fact that I'm working with CIV 3d 2010 have anything to do with it?

I attached the drawing with the polylines.

With regard to my post, it *shouldn't* as I used C3D 2011 to write and test that code from home yesterday.
