Design tool enhancements

Better communicate engineering data with new Apparent Load Calculation Options, Temperature Difference Parameter Type, and accounting for the Pressure Drop at tap fittings functionality.

Control the method used to calculate the electrical loads with Apparent Load Calculation Options. To meet load tabulation preferences, select to either sum the true load and reactive load, which is the default method, or sum the apparent load, a more simplified approach.

The new Temperature Difference Parameter Type simplifies design computations in family definitions. Easily compute the Delta T using the new unit type parameter, and use this value for other computations.

Provide more accurate pressure drop calculations on duct networks by associating a pressure drop table with duct fitting taps.  Revit then computes the pressure drop along the main and at the branch at tap fittings.
