Turn Rule

Overview

This section provides a brief overview of the Turn Rule 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 Piping/Tubing Design Resources.
when using Engineering Specification objects, a specification in the resource table of Piping/Tubing Specification Resources.

Rule Customization

This section describes the customization options of the Turn Rule.

File-Based Table

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


V_Standard (string)	DS_Material (string)	V_NominalSize (string)	DS_BendRadius	DS_DiameterFactor	DS_BendDiameter	V_NominalBendradius (string)	Comment (string)
SSTL	Aluminum	3/16in	0.376in	0	0in
SSTL	Aluminum	1/4in	0in	2	0.25in	2D	Preferred
SSTL	Aluminum	5/16in	0in	2	0.313in	2D	Preferred
SSTL	Aluminum	3/8in	0in	2	0.375in	2D	Preferred
SSTL	Aluminum	1/2in	0in	2	0.5in	2D	Preferred
SSTL	Aluminum	5/8in	0in	2	0.625in	2D	Preferred
SSTL	Aluminum	3/4in	0in	2	0.75in	2D	Preferred
SSTL	Aluminum	1in	0in	2	1in	2D	Preferred
SSTL	Aluminum	1 1/4in	0in	2	1.25in	2D	Preferred
SSTL	Aluminum	1 1/2in	0in	2	1.5in	2D	Preferred
SSTL	Aluminum	2in	0in	2	2in	2D	Preferred
SSTL	Aluminum	2 1/2in	0in	2	2.5in	2D	Preferred
SSTL	Aluminum	3in	0in	2	3in	2D	Preferred
SSTL	Nickel	1/4in	0in	3	0.25in	3D
SSTL	Nickel	5/16in	0in	3	0.313in	3D
SSTL	Nickel	3/8in	0in	3	0.375in	3D
SSTL	Nickel	1/2in	0in	3	0.5in	3D
SSTL	Nickel	5/8in	0in	3	0.625in	3D

To customize the table, enter a line in the spreadsheet for each standard and nominal size in every material you use.


Parameter	Type	Importance	Input / Output	Description
V_Standard	String	Required	Input	Used for filtering.
DS_Material	String	Required	Input	Used for filtering.
V_NominalSize	String	Required	Input	Used for filtering.
DS_BendRadius		Optional	Output	Enter value required for each standard, material and size.
DS_DiameterFactor		Optional/Required	Output	Used for calculation if DS_BendRadius does not contain a value.
DS_BendDiameter		Optional/Required	Output	Used for calculation if DS_BendRadius does not contain a value.
V_NominalBendRadius	String	Optional	Output	Provides information only. Displayed in properties of an object and in Turn Rule dialog box.
Comment	String	Optional	Output	Provides information only. Displayed in Turn Rule dialog box.

If there is no value (0) in DS_BendRadius, then the app tries to determine a bend radius value by multiplying DS_DiameterFactor by DS_BendDiameter.

As an example, for Row 2 in the table above, the diameter factor (2) multiplied by the bend diameter (0.25) will be the bend radius.

Engineering Specification Table

A typical Turn Rule Engineering Specification table is shown below:


Nominal Size	Wall Thickness	Material	Material Category	Bend Radius	Diameter Factor	Bend Diameter	Nominal Bend Radius	Physical Part Subtype
