Consistency checking verifies the suitability of work that a designer performs while creating the drawing. The software verifies, in real-time, if the composition of a drawing and the underlying data model satisfy rules that your company has defined. The software includes pre-defined standard industry design propagation: for example, pipe runs inherit properties from nozzles. Additional consistency checking and design propagation are defined in Rule Manager.

Consistency checking continuously monitors your work when you change or add items on a drawing. The software displays all the inconsistencies, describes specific problems, and offers hints. Using these solutions, you can decide the best method to resolve an inconsistency. One solution is to approve a warning and thereby remove the inconsistency from the drawing. Another solution is to copy the same value from one side to the other side and then propagate.

This illustration shows the inconsistency indicators that highlight incorrect relationships at a junction of items in a drawing. An error appears where the pipe run connects to the pump nozzle (A). A warning appears at the point where the valve and pipe run intersect (B). An approved warning accompanies the off-page connector (C).

Consistency Checking and Break Labels

A property break is a point in a connected network of objects where a property value changes. A user can define a property break by the placement of a break label. A property break is an exception to the consistency criteria defined in a rule. A property break defines a limitation to the spread of the propagation scope. Whereas rules provide the general definition of the scope, property breaks provide specific limitations of the scope.

The Consistency Check Dialog shows the consistency criteria that apply at the selected relationship indicator. All of the properties that are copied and compared across this connection are shown. After placement of a break label, the copy and compare columns show icons that indicate that no copy and compare operations are performed for the properties in the label.

Break labels can be created in the Catalog Manager environment. A break label is created just like an ordinary label, except that the Label Type property must be set to Attribute Break. A SmartText field must be created for each property that the break label is intended to break. A break label can break one or more properties. This functionality is all currently supported by the Catalog Manager. No new functionality is required.

Break labels can be placed directly from the Catalog Explorer. A group of break labels is currently delivered under Piping\SegmentBreaks. Break label placement is enhanced so that a break label can only be placed at a connection point where the specified properties are being propagated. When a break label is placed interactively, the corresponding property break data is added to the Relationship object.

Break labels can be deleted in the standard way using the Delete command. When a break label is deleted the break is removed from the Relationship object. However, if there is another break label at this same point that also breaks this property, then the break would not be removed.

Redundant breaks do not appear as inconsistencies on drawings. To identify these, you must use the Find Redundant Breaks command. Redundant breaks are break components, attribute breaks, and pipe segment breaks where those properties for which a discontinuity is expected are the same on either side of the break.
