To create a new rule or modify an existing one, click Element Rules to display the Define Rules window.

Location

Rules can be located in several areas. Dependent on the selected Location using the drop-down rules are stored in:

User

%AVEVA_DESIGN_USER%\des-element-rules.pmldat

Project

<MDB>\bspdflts\des-element-rules.pmldat

For example, BSP\bspdflts\des-element-rules.pmldat

Default

%PMLUI%\dflts\ des-element-rules.pmldat

Name

Enter a Name for the new rule in the text box.

Types

Enter the Types in the text box, which is a standard four-letter word which defines the type of element in the Design database hierarchy.

Note:
Rules for the elements with descriptions to Piping Zone, Steel Zone and Equipment Zone would all have their Type set to ZONE.

Rule

A logical selection Rule must be defined to identify any type of element for which the Type alone is not a sufficient specification. A selection rule is defined as the evaluated result of a PML expression.

Note:
The Type ZONE can apply equally to a Piping Zone, a Steel Zone, an Equipment Zone, each of which requires a different rule.

If no selection rule is defined for a given rule, the rule is applied to all elements of the specified Type.

Description

Enter a brief text string showing the type of element to which the rule is to be applied.

Click Include or Replace (an existing rule), if you want to save the changes it has made and then click Apply to close the window.

To bring the rule into use, you must add it to the list of rules on the Auto Colour Rules or Naming Rules window.

To remove a rule, highlight it in the Defined list and click Remove.

Once you have completed configuring the Colour settings, click Apply to apply the settings. Click Cancel to discard any changes made.

Click Load or Save, to load from and save to the options files stored at %AVEVA_DESIGN_USER%.
