FamilySymbol
The FamilySymbol class represents a single Type within a Family. Each family can contain one or more family symbols. Each FamilyInstance has an associated FamilySymbol which can be accessed from its Symbol property.
Thermal Properties
Certain types of families (doors, windows, and curtain wall panels) contain thermal properties as shown in the Type Properties window below for a window.
The thermal properties for a FamilySymbol are represented by the FamilyThermalProperties class and are retrieved using the FamilySymbol.GetThermalProperties() method. The FamilyThermalProperties for a FamilySymbol can be set using SetThermalProperties(). The properties of the FamilyThermalProperties class itself are read-only.
The units for the calculated values are shown in the table below.

The AnalyticConstructionTypeId property is the construction gbXML type and returns the value that corresponds to the 'id' property of a constructionType node in Constructions.xml. The static FamilyThermalProperties.Find() method will find the FamilyThermalProperties by the 'id' property of a constructionType node in Constructions.xml.
