Defines the consistency criteria for a rule.
Consistency Criteria
Lists the values for applying consistency criteria when items are placed in a drawing.
(Property of Item 1)
The header displays the Item 1 Name value as shown on the Items Tab. Each data row in the column displays the name of the Item 1 property to be used for consistency checking and System Editing.
Copy
The copy action to be performed is displayed in this column. This column controls how the property value is propagated when System Editing is turned on. The following table describes the possible values and their meanings.
|
Copy Action Symbol |
Copy Action Name |
Property Modification |
|---|---|---|
|
< > |
Copy Bi-directional Always |
The value can be copied in either direction during propagation. |
|
< |
Copy Item2 to Item1 Always |
The value from Item 2 is copied to Item 1 during propagation. |
|
> |
Copy Item1 to Item2 Always |
The value from Item 1 is copied to Item 2 during propagation. |
|
< > |
Copy Bi-directional if Null |
The value can be copied in either direction during propagation but only if the current value on the target item is Null. |
|
< |
Copy Item2 to Item1 if Null |
The value from Item 2 is copied to Item 1 during propagation but only if the current value on Item 1 is Null. |
|
> |
Copy Item1 to Item2 if Null |
The value from Item 1 is copied to Item 2 during propagation but only if the current value on Item 2 is Null. |
|
None |
The property is not propagated across this relationship. |
Compare
Displays how the property values from Items 1 and 2 are compared. The comparison occurs whenever any property on either item is changed. The following table describes the possible values and their meanings
|
Comparison Operator |
Meaning |
|---|---|
|
None |
No comparison |
|
= |
Equal |
|
< |
Less than |
|
<= |
Less than or equal to |
|
> |
Greater than |
|
>= |
Greater than or equal to |
|
<> |
Not equal to |
When applied to the Process Pipe Run To Process Pipe Run rule, the Copy and Compare operators determine the behavior of pipe runs joined by a collinear connection.
(Property of Item 2)
The header displays the Item 2 Name value as shown on the Items tab. Each data row in the column displays the name of the Item 2 property to be used for consistency checking and System Editing.
Status
Defines the display status of the inconsistency marker when an inconsistency is generated. If this value is set to Error, the inconsistency marker appears as a red X in your drawing. If it is set to Warning, the marker displays a blue exclamation point. This list appears after you select the field.
Severity
Displays a list for you to specify the severity of the inconsistency. Severity displays as a number between 1 and 10.
The following columns display when both Item 1 and Item 2 are used. For example, Nominal Diameter is frequently different in a branch as compared to the main run it connects to. Therefore you might want to set the value for Non-colinear to None for the Nominal Diameter property.
Colinear Copy
Defines the copy action to be used at a colinear connection. The values available for selection for this column are the same as those in the Copy column.
To specify the copy action at a colinear connection, you must set the value in the
Copy column to be the same as the value for this column.
Colinear Compare
Defines the comparison operator to be used at a colinear connection. The values available for selection for this column are the same as those in the Compare column.
To specify the comparison action at a colinear connection, you must set the value
in the Compare column to be the same as the value for this column.
Non-colinear Copy
Defines the copy action to be performed at a non-colinear connection. The values available for selection for this column are the same as those in the Copy column.
Non-colinear Compare
Defines the comparison operator to be used at a non-colinear connection. The values available for selection for this column are the same as those in the Compare column.
The following commands can be used to add and delete rows in the Consistency Criteria table.
Add
Adds a new row to the bottom of the list of consistency criteria. You must select the name of the Item 1 property from the drop-down list in the first column. Default values for the remaining columns are automatically displayed.
Add All
Fills in the table with default values for all matching properties of Item 1 and Item 2. For each matching pair, the Compare field is set to "=" by default, and the Copy field is set to "|" (None).
Delete
Removes the selected rows. It is enabled when one or more rows in the consistency criteria list are selected.
-
If no consistency criteria are defined for a particular property of an item, that property is not copied or included for comparison.
-
When joining pipe runs, Copy criteria are ignored for properties on pipe runs unless the value of the property is the same on both pipe runs prior to joining or if the property has a null value on the pipe run that is the target for the criterion.
-
For relationship rules where the Item 1 and item 2 are of the same item type, to determine which item is which, select one of the items in the drawing, right-click and on the shortcut menu, select Consistency Check. In the dialog that opens, select the Highlight item 1 and Highlight item 2 check boxes to highlight each item in the drawing.
-
To see the results of a changed Copy or Compare action after saving the rule, you must close and reopen the drawing.
-
When defining consistency criteria in a rule, and the property you select is a connect point (Piping Point, Ducting Point or Signal Point) property, you are not defining a specific connect point. The specific connect point is defined dynamically by the software when the rule is applied to a specific relationship. Although the displayed property name in the Rule Properties dialog might display End 1 Nom Diam, it actually means the Nominal Diameter property on that connect point in this relationship.
-
It is possible that no matching properties can be found for the two items. If no match is found, defining consistency criteria for the two items is not possible.
-
You can highlight one or several rows by selecting the row tab at the far left side. A row marker is shown to indicate the current row. After a row or several rows are selected, you can delete the rows by pressing Delete or change the Compare, Status, Severity, and Copy values for selected rows by selecting on the appropriate heading and choosing from the list.
