Parametric dimensions and tolerances

I don't know if this is API or not because I'm not reallysure what API is, but I want the ability to have dimensions andtolerances that are parametric. Is there anyway to write notes ordimensions and actually type out the D6@Sketch1 etc.? A largemajority of the time the insert model dimension function does notwork for me, hence I can't get any of my tolerance data from themodel. Being able to do this would save me a lot ofheadaches.SolidworksApi macros
