3d polyline export to *.txt
« on: April 30, 2014, 12:54:29 PM »
Hi ,I am trying to export 3d polyline coordinates and elevetion to *.txt file

the export file must be  (x,y,z)  like this

Quote
270.309,359.292,125.32
299.161,467.638,45.32
376.760,475.590,65.23
517.036,475.590,45.65

here is my code .I have an export problem and i need some help

Code - Auto/Visual Lisp: [Select]
  1. (defun c:3dpe ()
  2.   (setq sset (ssget '((-4 . "<OR")(0 . "POINT")

Replace (cond) statement for POLYLINE entity with this piece...

Just a quick glance but I do not see WRITE-LINE anywhere in the code. That would explain an empty text file.

I'll give you a hint .. the error is on this line: (while (/= (cdr (assoc 0 (setq v (entnext v)))) "SEQEND")


Take a look at what ASSOC requires and look at what is being passed.
And you still need to include WRITE-LINE.

Hi Topographer
Try this out

Hi fixo, Thank you for the code .I make this change to your code and work fine

Code - Auto/Visual Lisp: [Select]
  1.               ((= obj "POLYLINE")
  2.                (setq v hnd)
  3.                (setq vexx (3dpoly-verts v ))
  4.                (foreach pnt vexx
  5.                 (write-line (strcat (rtos (car pnt) 2 3) ","
  6.                                (rtos (cadr pnt) 2 3) ","
  7.                                (rtos (caddr pnt) 2 3)) fh)
  8.  
  9.  
  10.         )

Not possible, for all the post he is not learning much, just trying to cob together some surveying functions so he does not have to buy a canned program....
