Directional Length

Overview

This section provides a brief overview of the Directional Length tables.

The directional length is the minimum length of the straight routable portion connected to a port.

In Data Setup, this table should be assigned to:

when using file-based tables, the Directional Length item in the resource table of HVAC Design Resources.
when using Engineering Specification objects, a specification in the resource table of HVAC Specification Resources.

Table Description

This section describes the customization options of the Directional Length tables.

File-Based Table

A typical Directional Length file-based table is shown below.


V_Equivalent Diameter	V_Shape	DS_Material	V_EndStyle	V_DirectionalLength

Engineering Specification Table

A typical HVAC Directional Length Table is shown below:


Equivalent Diameter	End Style	Shape	Wall Thickness	Material	Material Category	Directional Length	IsFlexible

Note: You have to add the IsFlexible column. If the value is 1, the row is considered for flexible route. if the value is 0 or <unset>, the row is considered for rigid route.

The columns definitions are as follow:


Column Name	Column Type	Link to Table	Link to Column
Equivalent Diameter	Nominal Size	Duct Reference Dimension	Equivalent Diameter
End Style	String	Duct Reference Dimension	End Style
Shape	String	Duct Reference Dimension	Shape
Wall Thickness	Length	Duct Reference Dimension	Wall Thickness
Material	DS Material	Duct Reference Dimension	Material
Material Category	String	Duct Reference Dimension	Material Category
Directional Length	Length	-	-
Is Flexible	Integer	-	-
