Using a variable with dimpost command

[Charlesv]

Hi,

This is my very first post hope everyone is doing well. Anyway Im trying to use a variable within the dimpost command.

 

This works fine as is...but no variable yet...just a prefix to the dimension.

(command "dimpost" "SPACES @ 16\u+0022 = ")

 

This is what I would like to do...

(command "dimpost" "VAR1 SPACES @ 16\u+0022 = ")

VAR1 is the variable that I would like to show...not sure how to do the syntax.

 

Any help would be much appreciated...

 

Thanks

Look into strcat function

You should have the variable VAR1 as string .

 

(strcat VAR1 "SPACES @ 16\u+0022 = <>")

Thanks for the welcome guys and your quick replies! So I need to create a new variable say VAR2 which will make VAR1 a string?

If so what would the code look like? Not sure how to make VAR1 a string.

 

so the code for my dimpost command would look like...

(command "dimpost" (strcat VAR2 "SPACES @ 16\u+0022 = ")

[Tharwat]

What is the value of the Var1 ?

And what is the use of the var2 you looking for ?

[Charlesv]

VAR1 will change depending on user input. As for VAR2 I dont need it....just thought I would have to create a new variable which converted VAR1 to a string for use in my dimpost code.

This time , look into:

rtos

angtos

itoa

[Tharwat]

Check this simple routine ...

 

 

(defun c:var (/ var)
 (if (/= ""
         (setq var
                (getstring t "\n Enter string to be assigned to a prefix :")
         )
     )
   (setvar 'dimpost (strcat var " SPACES @ 16\u+0022 = <>"))
 )
 (princ)
)

a little bit extra codes removed

(/= var nil)

 

getstring will not return nil

[Tharwat]

getstring will not return nil

 

Oh correct , Thanks a lot .

[Charlesv]

Is there anyway to avoid asking for additional user input?

The dimpost variable is changed just before placing the dimension

then back to normal after the dimension is placed. Was hoping to

just add the VAR1 to it.

I appreciate the help guys!! After looking at what you guys were suggesting I ended up with this...

 

(command "dimpost" (strcat (rtos var1 5 0) " SPACES @ 16\u+0022 = "))
