Overview

This section provides a brief overview of the Turn Rules tables.

The Turn Rules table allows you to manage a routable turns. It is composed of input columns referring to the Reference Dimension table, and output columns that define the authorized values for the Bend Radius and if a specific part should be used to realize the turn (specific elbows, nothing...).

The Bend Radius column contains the bend radius to be applied. If it is equal to 0mm or Unset, the combination of Bend Diameter and Diameter Factor gives the value of the Bend Radius with the following formula : "Bend Radius"="Bend Diameter"*"Diameter Factor". The value inside the Nominal Bend Radius is used to value the corresponding attribute on objects. It is only informative and not used by the app.

Note that the Bend Radius column represents the Inner Bend Radius in case of non-circular shapes.

In Data Setup, this table should be assigned to:

when using file-based tables, the Turn Rule item in the resource table of Raceway Design Resources.
when using Engineering Specification objects, a specification in the resource table of Raceway Specification Resources.

Table Description

This section describes the customization options of the Turn Rule tables.

The following table describes the meaning of each column.


Parameter	Type	Importance	Input / Output	Description
Nominal Size	String	Required	Input	Used for filtering.
Realization Type	String	Required	Input	Used for filtering.
Shape	String	Required	Input	Used for filtering.
Height	Length	Required	Input	Used for filtering.
Width	Length	Required	Input	Used for filtering.
Material	Material	Optional	Input	Used for filtering.
Material Category	String	Required	Input	Used for filtering.
Wall Thickness	Length	Required	Input	Used for filtering.
Bend Radius	Length	Optional	Output	Enter value required for each standard, material and size.
Turn Case	String	Optional	Output
Physical Part Subtype	String	Optional	Output	Part Subtype to use to create the bend.

File-Based Table

A typical Turn Rule file-based table is shown below:


V_NominalSize	V_RealizationType	V_Height	V_Width	V_Shape	V_Material	WallThickness	BendRadius	Comment

Important: The columns must all be found in this order to be correctly read by the app.

Engineering Specification Table

A typical Raceway Turn Rule table is shown below:


Nominal Size	Realization Type	Shape	Height	Width	Material	Material Category	Wall Thickness	Bend Radius	Turn Case	Physical Part Subtype

The columns definitions are as follow:


Column Name	Column Type	Link to Table	Link to Column
Nominal Size	Nominal Size	Tray Reference Dimension	Nominal Size
Realization Type	String	Tray Reference Dimension	Realization Type
Shape	String	Tray Reference Dimension	Wall Thickness
Height	Length	Tray Reference Dimension	Height
Width	Length	Tray Reference Dimension	Width
Material	Material	Tray Reference Dimension	Material
Material Category	String	Tray Reference Dimension	Material Category
Wall Thickness	Length	Tray Reference Dimension	Wall Thickness
Bend Radius	Length	-	-
Turn Case	String	-	-
Physical Part Subtype	String	Physical Part Subtype	Physical Part Subtype

The table has the following attributes:

Standard
Circuit Type

Sample Resource File

This section explains where to find the sample resource file.

The default location of XXX_XXX_TurnRules.xls is:

..\startup\EquipmentAndSystems\Tray\Specification\

and then the relevant specification, such as SS150R.
