I don't know if this is the correct terminology, but is there a list of suffixes used for measured data/features and the like? For example, if I have a feature named CIRCLE1 that has been measured, I can usually use it's X and Y location data as CIRCLE1.X or CIRCLE1.Y in a generic feature. I know there are other suffixes designated for diameters, nominals, measured values, etc., but I always forget the correct syntax for them. Is there a list somewhere that has all these suffixes and what they represent?
