Duct Reference Dimension

Overview

This section provides a brief overview of the Duct Reference Dimension tables.

The Duct Reference Dimension tables list all the ducts or other routable components available to the user within a duct specification.

The table shows all sizes and certain other parameters.

In Data Setup, this definition table should be assigned to:

when using file-based table, the Duct Reference Dimension item in the resource table of HVAC Design Resources.
when using Engineering Specification objects and depending on the usage:
- the Duct Reference Dimension item in the resource table of HVAC Specification Resources.
- a Parts Filter in a specification in the resource table of HVAC Specification Resources.

Table Description

This section describes the customization options of the Duct Reference Dimension table.

File-Based Table

The table appears when you click the Route Size Table button while routing. For each duct specification, you need to create a table listing the materials and other attributes permissible in your project.

A typical Rigid Duct Reference Dimension file-based table is shown below:


V_EquivalentDiameter	V_Shape	V_MaterialName	V_Height	V_Width	V_CornerRadius	V_WallThickness	V_MaxLength
100mm	Rectangle	Steel	100mm	300mm	0mm	5mm	0mm
200mm	Rectangle	Steel	200mm	500mm	0mm	5mm	0mm
100mm	Rectangle	Steel	100mm	300mm	20mm	5mm	0mm
200mm	Rectangle	Steel	200mm	500mm	20mm	5mm	0mm
100mm	FlatOval	Steel	100mm	300mm	0mm	5mm	0mm
200mm	FlatOval	Steel	200mm	500mm	0mm	5mm	0mm

To customize the table, enter a line in the spreadsheet for each standard, equivalent diameter, shape, height, and width that you use.


Parameter	Type	Importance	Input / Output	Description
V_Standard	String	Required	Input	Used for filtering
V_EquivalentDiameter	String	Required	Input	Used for filtering
V_Shape	String	Required	Input
V_MaterialName	String	Required	Output	The material used for the duct. It will be applied if found in the material catalog.
Height	Length	Required	Input
Width	Length	Required	Input
V_CornerRadius	Length	Required	Input
V_WallThickness	Length		Output
V_MaxLength	Length		Output

A typical Flexible Duct Reference Dimension file-based table is shown below:


V_Standard	V_EquivalentDiameter	V_MaterialName	V_OutsideDiameter	V_WallThickness	V_MaxLength

To customize the table, enter a line in the spreadsheet for each standard and equivalent diameter, shape, height, and width that you use.


Parameter	Type	Importance	Input / Output	Description
V_Standard	String	Required	Input	Used for filtering
V_EquivalentDiameter	String	Required	Input	Used for filtering
V_MaterialName	String	Optional		The material used for the pipe or tube. It will be applied if found in the material catalog.
V_OutsideDiameter	Length	Required
V_WallThickness	Length	Required
V_MaxLength	Length	Optional

Note: Values in the Duct Reference Dimension tables are independent of the values you enter in the discrete list tables.

Important: Any material you specify in the Duct Reference Dimension table must exist in the database. There is a specific procedure for creating material - you must use this procedure and save the material in the database first. For more information, see the 3DEXPERIENCE Native Apps and the Material Definition User's Guide. The name in the DS_Material column must match the name in the database. Also note that material names in the database must be unique. If you have two entries with the name nickel in the database then, when you are routing a nickel duct, you will get an error message and material will not be applied to the duct.

A V_LinearWeight column can be added in this table listing linear weights. If this column is not defined in the table, the value of linear weight will be considered as zero.

Engineering Specification Table

Table

The table is used for attributes valuation on ducts when you create reference parts outside of specification context.


Equivalent Diameter	Shape	Material	Material Category	Height	Width	Corner Radius	Wall Thickness	Maximum Length
100mm	Rectangle	Steel	Steel	100mm	300mm	0mm	5mm	0mm
200mm	Rectangle	Steel	Steel	200mm	500mm	0mm	5mm	0mm
100mm	Rectangle	Steel	Steel	100mm	300mm	20mm	5mm	0mm
200mm	Rectangle	Steel	Steel	200mm	500mm	20mm	5mm	0mm
100mm	FlatOval	Steel	Steel	100mm	300mm	0mm	5mm	0mm
200mm	FlatOval	Steel	Steel	200mm	500mm	0mm	5mm	0mm

The columns definitions are as follow:


Column Name	Column Type	Link to Table	Link to Column
Equivalent Diameter	Nominal Size	Equivalent Diameter	Equivalent Diameter
Shape	String	Equivalent Diameter	Shape
Material	Material	Material	Material
Material Category	String	Material	Material Category
Height	Length	Equivalent Diameter	Height
Width	Length	Equivalent Diameter	Width
Corner Radius	Length	Equivalent Diameter	Corner Radius
Wall Thickness	Length	-	-
Maximum Length	Length	-	-

The table has the following attribute:

Standard

Parts Filter

Parts Filter are used when you create ducts in a specification context.

Working in a specification context, Parts Filter are computed to give the duct allowed in the current specification instead of building a query on database or catalog from the duct reference dimension table.

Sample Resource File

This section explains where to find the sample resource file.

The default location of XXX_XXX_DuctReferenceDefinition.xls is

..\startup\EquipmentAndSystems\Duct\Specification\

and then the relevant specification, such as SS150R.
