Not sure about 2003, but in the later models you can put your standard distance mate in, then go back in the feature tree and double click the mate, the dim will show up in the graphics window, click the radio dim on the side [to link dim's or add a equation] and add the equation. You can also just go up to the tools menu, add an equation.. then you click the double click the first mate, select it in the graphics screen,it will appear in the equations line, set it = to the second or whatever your equation is.. and off you go on your marry way
Jerry [this applies to 2006, but I can't garrentee it applies to 2003.. but its worth a try]
