Turn Rules Definition Table | ||

Overview
This section provides a brief overview of the Turn Rules.
The turn rules definition table allows selection of the bend radius during routing. The bend radius is either computed with data entered in a table, or selected by users from a table.
In Project Resource Management, this definition table should be assigned to:
The Turn Rules Definition Table item in the resource table of Piping/Tubing Design Resources.
Rule Customization
This section describes the customization options of the Turn Rules.
A typical Turn Rules Definition Table is shown below.
To customize the table, enter a line in the spreadsheet for each standard and nominal size in every material that you use.
| Parameter | Type | Importance | Description |
|---|---|---|---|
| V_Standard | String | Required | Used for filtering |
| DS_Material | String | Required | Used for filtering |
| V_NominalSize | String | Required | Used for filtering |
| DS_BendRadius | Optional | Enter value required for each standard, material and size | |
| DS_DiameterFactor | Optional/Required | Used for calculation if DS_BendRadius does not contain a value | |
| DS_BendDiameter | Optional/Required | Used for calculation if DS_BendRadius does not contain a value | |
| V_NominalBendRadius | String | Optional | Provides information only. Displayed in properties of an object and in Turn Rules dialog box. |
| Comment | String | Optional | Provides information only. Displayed in Turn Rules dialog box. |
If there is no value (0) in DS_BendRadius, then the application will try 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.
