Move Text to *Line along text rotation

October 9, 2019

Hello Everyone !

The posted code is working fine as per the attached image. They text are move follow with green line direction but I need move text follow with magenta line direction in selected line or Polyline.

Can anyone help me!

Code :

(Defun c:alt  (/ li txts e)
      (if
            (and (princ "\nSelect Line for Alignment")
                 (setq li (ssget "_:L" '((0 . "LINE"))))
                 (princ "\nSelect Texts to Align")
                 (setq txts (ssget "_:L" '((0 . "TEXT,MTEXT")))))
                 (repeat (sslength txts)
                       (vla-move
                             (setq e (vlax-ename->vla-object
                                           (ssname txts 0)))
                             (vla-get-insertionpoint e)
                             (vlax-3d-point
                                   (vlax-curve-getclosestpointto
                                         (ssname li 0)
                                         (vlax-get e 'insertionpoint)))
                             )
                       (ssdel (ssname txts 0) txts)
                       )
                 )
      (princ)
      )

Are you happy with move based on angle of text ? This would use a xline and intersectwith

; By Alan H Oct 2019
; moves text along text angle to a *line

(defun c:pushtxt ( / ss ang obj obj2 obj4 pt1 pt2 pt3 ent)
(setq obj (vlax-ename->vla-object (car (entsel "pick Line "))))
(setq ss (ssget (list (cons 0 "*text"))))
(repeat (setq x (sslength ss))
(setq ent (ssname ss (setq x (- x 1))))
(setq obj2 (vlax-ename->vla-object ent )) 
(setq Pt1 (vlax-get Obj2 'Insertionpoint))
(setq ang (vlax-get Obj2 'rotation))
(setq pt3 (polar pt1 ang 10))

As the OP wants to move to a line or pline I can see a problem arising if the xline cuts the pline more than once, when intpt will become a list min length 6 (2 points), so you would have to find the nearest intersection point.

No not working

How is it not working?

What error message are you getting?

Are you trying to use this with a polyline or a line?

If with a polyline try it with a line.

Is the visual lisp arx loaded? If not put (vl-load-com) at the top of the file and try again

@dlanorh

Yeah i'm try with line but they text are not move in line.

I got some error See the attached file .

It will move the text to the nearest intersection (if more than 1) using the text angle. See attached dwg

MT2L.dwg

I just tested again and working fine is the angle of the text such that a intersection point is not visually calculated ?

This will force a calculation extending lines replaced in code above

(setq intpt (vlax-invoke obj 'intersectWith obj4 acExtendboth))

Thank you so much!! yeah both code are now working fine Cheers @BIGAL @dlanorh

Hi @dlanorh,

I have to add some changes can you please help me!!

Above this code after creating xline, i want to move or offset xline (clockwise direction) distance is taken from dimscale.

October 18, 2019

Sorry I can't help at the moment as I am away and I don't have any version of AutoCAD etc with me. Will be back at the end of next week.
