addition and substraction to selected Station marking(MText)

May 29

Can anyone help to write lisp, so that it can add/substract Particular value to the selected mtext which are in 1+11 format. They should ask Add or substract the value{How much should I add or How much should I substract} and eg, if there is Station marking 0+20, 0+70, 1+20, 2+50, 11+21 and I give command SMADD and it should ask "how much should I add:" and then if I give value 70, then it should add 70 to whichever mtext I am selecting convert the existing Station marking to 0+90, 1+40, 1+90, 3+20, 11+91. Same with substraction.

You can try with DWG attached. And the lisp should not change text style, layer, size or color.

like this maybe?

(defun c:smadd (/ ss i addnum obj num)
  (setq ss (ssget '((0 . "MTEXT"))))
  (setq i 0)
  (setq addnum (/ (getreal "\nhow much should I add: ") 100))
  (while (< i (sslength ss))
    (setq obj (vlax-ename->vla-object (ssname ss i)))
    (setq num (+ addnum (atof (vl-string-subst "." "+" (LM:UnFormat (vla-get-textstring obj) t)))))
    (vla-put-textstring obj (vl-string-subst "+" "." (rtos num 2 2)))
    (setq i (1+ i))
  )
)

also beware that your text uses individual text formatting.
cant read the text values with it so using LM:UnFormat to remove it.

Still getting : ; error: no function definition: LM:UNFORMAT

Unformat is here: https://lee-mac.com/unformatstring.html - copy and paste the code to a text file and load as a LISP, maybe add it to the same as c:smadd above - before the LISP that refers to it is often better

yess after addition of text its working but changed those MTEXT style too. Is there any method will add without changing the Style?? and For substraction what needs to change?

The Lisp has to remove the individual text formatting since it cant read the values otherwise.

To retain the Formatting would be way more complicated.

Just type for example -20 or -50.

Quickly looking at the drawing, the mtexts in question all have formatting code 'p34;' - could use Lee Macs String to List using p34; as a delimitator, change the text portion and then list to string to remake the text again

also thought of saving the formatting in a list somehow, but didnt wanna dive into that

some edit of EnM4st3r's code.

ah.. my mistake.

~~Add and Subtract the last number of mtext with only one + or -.~~

~~When it becomes negative, + changes to -. It does not work if there are two or more +'s.~~

@exceed nice , this is smart didnt think about that.

(vl-string-subst rnum utext otext)

but i thought he wanted only the last 2 numbers behind the plus everything else should be added like infront of the plus.
So 0+48 added with +1000 should be 10+48

ah i understand. like this?

If the total number is negative, how should it be expressed? For example, if -0.40 then -0+40? -0-60?

Or Doesn't this work with negative numbers?

not sure, guess @smitaranjan needs to tell us more about the expected result

So 0+48 added with +1000 should be 10+48

yes this is what I wanted. 0+70 added 900 should be 9+70, 0+72 added with 2001 should be 20+73.....and for negative 0+10 substracted 50 then it should be 0-40 and from 0+21 substracted 129 then -1-08 may be although 0+00 will be the smallest value for my work

Edited May 31 by smitaranjan
Extra

May 31

what about 0+10 substracted 500?

-5-10? but since 0+00 ist the smallest value leaving it at -5+10 is the easiest.

ah i understand. like this?

If the total number is negative, how should it be expressed? For example, if -0.40 then -0+40? -0-60?

Or Doesn't this work with negative numbers?

Its working perfectly.

what about 0+10 substracted 500?

-5-10?

that mostly not required as 0+00 will be the starting and all the Station marking will be greater than and positive one. But for curiosity -4-90

Dear Exceed,

I appreciate your efforts and contribution but doubt the use of this code. Normally in station values, any number before the + sign is considered a Kilometer, and after that 3 places as meters and then a point with 2 or 3 decimal digits.
Now as per your definition, "So 0+48 added with +1000 should be 10+48" if 1000 or 1 Km is added to 48 or 480 meters it gives the result as "10+48" i.e, 10 Km and 48m whereas the correct answer should be 1+048 or 1+480 or 1+480.00 or 1.048.00.
Correct me if I am Wrong

In my case unit is feet. So the result I wanted and code written by @exceedmatches.

Depends where you are in the world here in AUS its Ch 1234.45. Postal addresses in remote areas on roads are like 1092 meaning 10920 m from a start point.
