Changing Layer Key Overrides with VBA or Lisp

[jgardner.79905]

I am trying to create a routine in lisp routine or VBA that will change the Layer Key Override automatically (see picture below). However, I do not know how to get to that information, I also can not fine anything even close. I have figured out how to toggle the overrides on and off just not how to change what the override is. As an example I would like to be able to have the routine to change the “Location” field from one preset value to another. If anyone has any suggestions or now how I could get help with this, it would be greatly appreciated.

Use AECSETLAYERKEYOVERRIDE fuction this is a arx fuction.

exp:

 (AECSETLAYERKEYOVERRIDE "Minor" "Dims")

ARX function is a function add to AutoLISP by a ARX program in this case the ARX program is ADT you use th function just like a AutoCAD function but if the ARX program is not loaded the function will not be there.

 
(AECSETLAYERKEYOVERRIDE "xxx" "yyy")

so in your code call the function replace xxx with
Location, Plan or Item

replace yyy with the value you what it be set to

Put this code in a toolbar button

^C^C(AECSETLAYERKEYOVERRIDE "Location" "yyy")

replace "yyy" with new value for location
