You can apply rules to pipe network parts to ensure that certain conditions are flagged, and to ensure that parts are placed in correct locations.
For example, you may need to reapply rules to ensure that pipes that have not met the maximum cover value are flagged as rule violations. This enables you to quickly identify parts that may need to be adjusted in your drawing. You may also want to reapply rules after you moved a structure that has pipes connected to it to ensure that the connected pipes still exist in the correct elevation and connection locations.
When you apply rules to a pipe network part, rule values as defined in the Pipe Rule Set or Structure Rule Set for the part are copied to the part.
You may need to reapply rules when:
- The elevation of a pipe network part has changed due to pipe network parts being moved.
- A part’s rule value has changed.
- You add or delete a rule from a part.
- You change the order in which rules are processed on the part.
If you look at the rule set assigned to a part, you can view the rule set, and the rules currently associated with the part. You cannot change the processing order of the rules on the Structure or Pipe Properties Rules tab. However, you can change the order of the rules by displaying the Rules tab on the Rule Set.
Applying rules does not automatically resolve rule violations. You can view rule violations leave them as is, or resolve them.
In some situations, reapplying rules may result in more rule violations, some of which you may decide to simply leave as violations. For example, there may be some situations where you have site-specific cover constraints that you want to intentionally violate.
