At my company, one of the most consistently annoying hurdles that we have to deal with are Built-In Parameters. The fact that Built-In Parameters like "Short Circuit Rating" in Electrical Equipment are not schedule-able and cannot be used in Tags has caused us to create extra parameters that have all of the same characteristics as the built-in parameters, but either feed their value from the built-in param or are used entirely separately from it. Not only does this cause unnecessary confusion and chaos on work shared projects with regard to the correct parameter to use, but it also causes unnecessary bulk in our Revit Model. Please either add the ability to purge unused Built-In Parameters, or allow the ability to schedule out and use these parameters in tags.
Thank You,
James Kerfoot
