Martin Schmidt MEP Customer Success Engineer at Autodesk has developed a very nice Mechanical Application which is currently featured in the Autodesk Labs as the Plug-in of the month! His app will allow a user to select any number of duct fittings, browse the various ASHRAE fitting lookup tables, their associated diagram, and then update all the fittings with the correct lookup table you have selected.
This is a great improvement from where we currently sit today where we have to break out our ASHRAE books or punch up the program to check what "SD4-10" means... I mean not that I don't have all 200 tables memorized or anything! The ability to have a visual identification system built directly into Revit is a great enhancement and something I spoke to Martin about back in Novemember.
It great to see Martin taking the initiative and adding his own enhancement to the factory program. I hope to see this built into the first service pack for RMEP 2012. Check it out and let me know what you think with a comment below. http://labs.autodesk.com/utilities/adn_plugins/
