This ?

 

(getvar 'gridunit)

[marko_ribar]

I think yes, the same :

 

(defun c:grids ( / g )
 (setq g (getvar 'gridunit))
 (setq g
   (cond
     ((getpoint (strcat "\nSpecify new gridunit variable <" (rtos (car g)) "," (rtos (cadr g)) "> : ")))
     (g)
   )
 )
 (if (caddr g) (setq g (list (car g) (cadr g))))
 (setvar 'gridunit g)
 (princ)
)

Thanks marko_ribar and Tharwat

but gridunit sys variable specifies grid spacing for the current viewport. I am trying to get a user-defined Grid scale that is set from drawing settings window in transformation tab.

If you want to set the grid scale manually , how would you set it ?

 

I couldn't find transformation tab in the Drawing Settings Window in my Autocad 2014

on the command line I type in "editdrawingsettings" and then click on transormation tab and set the user-defined grid scale factor value

That option might be available only in Civil cad as it is shown into your profile , can you upload a snapshot of that dialog ?

This is only available in civil3D

I would try with command sysvdlg and type there *grid*, and if there is sysvar for grid scale factor, then it should be simple to use (getvar "???") where ??? is that name of sysvar...

Unfortunately I do not either have or work with Civil3D but we have lots of nice guys in this forum using that Cad version and they are very helpful guys , so just wait and you should have your question answered in no time .

Thanks marko_ribar, unfortunatelly all the sysvariables about the grid didn't help
