System
Defines the system to which the duct run belongs.
Name
Defines the name assigned to the duct run.
Name Rule
Specifies the name rule to use for the duct.
Specification
Defines the specification assigned to the duct run.
Standard specification has allowable cross-sections defined by the system. You can only select the cross-section values from the list displayed. User defined specification has the allowable cross-sections defined by the system and it also allows you to key-in cross-section values that are not on the list.
Max. Recommended Velocity
Defines the maximum air flow velocity for the duct run.
Max. Recommended Pressure Loss
Defines the maximum pressure loss recommended for the duct run.
Material
Defines the material assigned to the duct run.
Thickness
Defines the thickness of the duct material.
Insulation Material
