    I am running AutoCAD 2002. I would like to make a block with 3 attributes associated with it. I want to be able to enter the a value for the first attribute, then have the values for the next attributes calculated using a simple formula. Ex. I want to be able to enter 25 as the value of my first attribute. For the value of my second attribute I want to display (25 -8) and have 17 displayed as the value of my second attribute.
    I am a real novice at Lisp so any advice in how to achieve this is greatly appreciated.

    Overly simplified, but this should get you started:

    (setq bname "block name to insert")
    (setq inspt (getpoint "\nSelect insertion point: "))
    (setq att1 (getint "\nBase number: "))
    (setq att2 (- att1 8)); or whatever
    (setq att3 (+ att1 4)); or whatever
    (command "-insert" bname inspt "" "" "" (itoa att1) (itoa att2) (itoa att3))
