About Basic Properties

Modify the basic properties of a duct using the properties palette.

Basic properties are expanded by default. The properties display the last stored value.

Note: In the following tables, properties related to Flange Connection Type are preceded by an asterisk (*), properties related to Takeoff Fittings are preceded by double asterisks (**), properties related to a flexible ducts are preceded by triple asterisks (***) and are only available when you modify the respective object.

General	Description
Description	Describes the object (optional).
Layer	Specifies the layer style for the selected object.
System	Specifies the system definition for the selected object.

Dimensions	Description
Routing preference	Specifies the routing preference for the selected duct object.
Shape	Specifies the shape for the selected object.
Size	Specifies the size in the routing preference for the selected object. There are different default size parameters, depending on the selected shape. Oval - Width and Height Rectangular - Width and Height Round - Diameter
Duct Calculator	Calculates the sizes of the duct based on the Flow Rate, Friction, Roughness and Density. If the shape is Rectangular or Oval, one Size Parameter has to be fixed to calculate the other one. Note: For more information, see Duct Size Calculator.
Size lock	Prevents the editing of the nominal size value while you are modifying the duct run.

Sizing	Description
Flow Rate	Specify the flow rate of the selected object. The flow rate value is read from the connected MvPart. If there's no MvPart connected, the value will be zero.
Friction	Shows the predefined friction of the selected object (Read-only). The value of friction is read from selected duct system.
Velocity	Specifies the system definition for the selected object.
Cut length	Specifies the reported value of the length of the duct.

Placement	Description
Elevation	Specifies the elevation of the duct object.
Start elevation End elevation	Specifies the elevation at the starting and ending points of the duct segment. Start/end elevation on Properties palette
Move attached segments	Lets you specify whether to move the attached duct segments if the location of the selected part has changed (default — Yes).

Routing	Description
*Slope format	Displays the current slope format (not editable).
*Slope	Specifies the slope value of the current duct segment (not editable).
