Is there a list of variables that can be used to compute marks? Is there a variable for the contract number project property? Is there a variable for the drawing scale, or do I have to build the string by concatenating the numerator and denominator with a ":" between? Can I get access to all the revision data attributes for filling in a title block, or only the attribute that show up when using the "replace attribute" command?
