Insulation Area calculation for duct fittings

[Anonymous]

When we apply insulation on duct fittings, the area is not computed. We know that insulation is a bit of a problem within Revit, bur we would love to see an increase of parameters and possibilities with insulation. One of them is the calculation of insulation area and volume. Thereby, we think that the insulation thickness should be a type parameter instead of an instance. 

If anyone has recommendations about insulation I would like to hear them. As a MEP engineer the insulation possibilities are just too poor.

The computation of the area of insulation can get quite complicated, as it requires fully understanding the development of the fitting itself for the sheet metal, and further, understanding the various ways by which the part may be wrapped or lined for insulation.  The fabrication duct components understand all this logic, and is one of the reasons these were implemented in Revit to support the 'make' process for this side of the industry.  Those parts do compute the area, which can be obtained through the Revit Extension for Fabrication Report or CSV export capability.  The additional weight of the insulation is included in the weight of the part itself as reported in Revit.  The functionality wasn't designed/developed w/ the 'engineer' in mind.. it is more targeted to the needs of the mechanical contractor that would need to procure, cut, fabricate, and install the insulated duct.  However, if insulation quantification is among your most important needs, this may provide you with a solution.

But you can add formula in schedule to calculate it separately. It is my way of doing it, hope this help.
=Area * (1 + (4 * Insulation Thickness) / (Width + Height)).
If you doing schedule for duct fittings and accessories. You will have to calculate the area inside of family first by using shared parameter.
