Hi,

I have thousands of drawings. They are all similar to This.dwg one.

My final goal is to merge them into one kml file..

This would take months to do it one by one.

If I have the right lisp to automate this in one drawing, then I can use script to run that lisp over other drawings.

 

To reduce the result file size, I decided to keep only the green polyline in the center of the drawing(which matters the most):

  

(defun C:foo ( / varf ins str)

;  Selecting Polyline
   (setq varf
       (list
          '(-4 . "<OR")
              '(0 . "LWPOLYLINE")
              '(-4 . "<AND")
                  '(0 . "POLYLINE")
                  '(-4 . "<NOT")
                      '(-4 . "&")
                      '(70 . 80)
                  '(-4 . "NOT>")
              '(-4 . "AND>")
          '(-4 . "OR>")
               (cons 62 3)
       )
   )
(sssetfirst nil (ssget "_X" varf))

; Inverting selection 
 (if (ssget "_I")
  (progn; then
   (sssetfirst nil)
   (command "_.select" "_all" "_remove" (ssget "_p") "")
   (sssetfirst nil (ssget "_p"))
  ) 
  (prompt "\nRequires pre-selection."); else
)

; Delete Selection
(command "_.erase")

; And This is how I insert Drawing Name 
  (and (or (> (getvar 'DWGTITLED) 0)
           (alert "Save the drawing then try again!")
       )
       (setq ins (getpoint "\nChoose Insertion Point: "))
       (setq str (entmakex (list '(0 . "MTEXT")
                                 '(100 . "AcDbEntity")
                                 '(100 . "AcDbMText")
                                 (cons 10 (trans ins 1 0))
		                 (cons 40   0.8);Text height
	                         (cons 7   "STANDARD");Text style
                                 '(1 . "")
                           )
                 )
       )
       (vla-put-textstring (vlax-ename->vla-object str)
			"%<\\AcVar Filename \\f \"%tc4%fn2\">%}"
       )
  )
)

 

Now these are what I'm looking for:

- I don't want to pick the insertion point manually,  need to insert field inside or over selected polyline 

- after inserting field text, I want to explode the text. to maintain drawing name after merge.

- adding a condition to check the process, if anything goes wrong, insert that drawing name at (0,0,0). this way I can track that file to check it manually.

Thank you in Advanced.

As a start I'll post this and see where you go from there. 

 

I've put your entmakex part into a sub-routine - easier for the next step where you insert the filename at the origin (saves copying the code twice) and copied in a small routine to get the centre point of an entity bounding box. Also gave your selection set a name (MySS) to make it easier to refer to later.

 

So this should now put the fllename in the centre of the first polyline in the selection set. Do you need the filename in all the polylines (the green boxes) ? noting in your example there are 2.  We can add a loop through the selection set (MySS) to do that  Wasn't looking at your drawing properly then, will need to delete the green outline that is in the border so the LISPs don't get confused as what to look at. I'll assume that the detail is always in the bottom of the border, that is below the green outlie that you want to keep?

 

For the filenames, is there a reason that you want to insert that as a field or can it just be inserted straight as a text string? (noting you mention conditional checking comes later)

 

 

Can modify this later if you let me know about the filename - in all the green boxes or not and enter as a string or field?

No doubt there will be other suggestions but this is based on what you have made up so far

Thank you Stephen,

- Not necessarily, filename can also be as string text.

- All of the green polylines the better.

Try this one,  it should put the filename in all the green boxes (noting this includes the green box in the border), plus filename in the origin (0,0) - try it and see and let me know any comments

all good except this. probably I didn't explain this part very well. adding filename in 0,0 must happen ONLY when there is some error. for example when there wasn't any green polyline in the loop.

I've updated the code quickly - it will put the filename in if there are no green lines selected, I'll need to copy and paste in some proper error checking though to do anything other than that - will be later maybe

I'm so sorry I called you Stephen back there. Thank you again Steven. Everything is working the way I wanted to.

Not a problem, (and if Stephen was the worst I am ever called I'd be a happy man.....)
