This line creates the text:

 

(setq Obj (vlax-invoke Space 'AddMtext P 0.0 (rtos Elev 2 2)))

 

searching about on the internet should give you solution and explanation, 

 

Add something like this on the next line, where ht is your text height - might need to alter the position of the text height line to make it work

(vla-put-textheight obj ht)

Use to check properties of entity's in AutoCAD.

;;----------------------------------------------------------------------------;;
;; Dump All Visual Lisp Methods and Properties for Selected Entity
(defun C:VDumpIt (/ ent)
  (while (setq ent (car (entsel "\nSelect Entity to Dump")))
    (vlax-Dump-Object (vlax-Ename->Vla-Object ent) t)
  )
  (princ)
)

 

Most are simple to change as (val-put-"property name" vla-object value)

Properties values listed with a (RO) are read only.

I can not understand how to use all this !!! Is any other easy way to use ht ?

 

Thanks

Hi mhupp. I add this line

 

(vla-put-textheight obj ht)

 

but i didn't see any difference , the text height didn't change

 

Thanks

@mhy3sx Give this a shot and let me know. :)

NOTE: Yo can press enter to accept the default scale factor or enter your desired one.

This lisp almost works for us.  I need to change the text style from standard to one of ours. 
I hope that sets the height using the style.

 

What parameters are being used for the text style?

Posted

oh and How to make the label have no decimal places too.  Thanks for any help.

Using Tharwats code?

 

Look at this section 

               (setq txt (entmakex (list '(0 . "MTEXT")
                                         '(100 . "AcDbEntity")
                                         '(100 . "AcDbMText")
                                         (cons 10 cls)
                                         (cons 1 (rtos (last cls) 2 2))
                                         (cons 40 (* 0.00175 *MHY:Scale*))
                                         (cons 8 "Contour Label")
                                         '(50 . 0.0)
                                         '(71 . 5)
                                         '(72 . 5)
                                         '(73 . 1)
                                         '(210 0.0 0.0 1.0)
                                   )
                         )
               )

 

Add '(7 . "Text_Style") where text style is your font in between '(50 . ...) and '(71 . ...). Here using Standard text style:

 

                                         '(50 . 0.0)
                                         '(7 . "Standard")
                                         '(71 . 5)

 

For height modify the (cons 40 (* 0.00175 *MHY@Scale*)) if necessary. Either change the 0.00175 to a different number or replace the whole (* 0.00175 *MHY:Scale*) to a value if you want the same height all the time eg. (cons 40 2.5)

Yes Tharwats code.

 

Let me give those changes a whirl. Thanks!!

Posted

Yes those fixes worked I almost have what I want.   Need to make the label have no decimal places too.  Comes in like first image but need second:

A very simple answer is, it is your turn to do a little home work and learn at same time.

 

Google "RTOS Autodesk"

 

Have a look in the code you should be able to find it very quickly what to change.

I am not the best at lisp routines but can edit them ok.  Thanks for the lesson.  I went online and found the syntax and edited it and now it is working well.

(cons 1 (rtos (last cls) 2 0))

Perfect - to be honest that is a much better answer than us just giving you the syntax! A little hint from BigAl, a bit of confidence that you can change the code and we can retire now?
