Class

Use the functionality to specify classes that are used in auto-acceptance and auto-assign-to-discipline rules for clash ownership. The Class tab is also used to set the classes in the order they are to be considered, when the relative importance of the class of each element within a clash is the subject of an automatic acceptance or assignment process

The functionality enables the values of an attribute to be associated with the values of the Plant class attribute for the purpose of automatic assignment of a class to a clash.

Note:
This configuration is separate from the Project Defined Field configuration on the Project tab.

The pane at the top of the tab enables a particular Plant Class Description and its Attribute Value to be selected. A Popup Menu is available (mouse right-click) with options of Edit, Add and Delete. This is used to edit an existing class, add a new class, remove an existing class, or set an existing class as default. The description is user-defined, the attribute value must match the attribute value for the particular class.

The associated Up and Down buttons are for rearranging the order of the classes, from top to bottom. The least important class is at the top; the most important at the bottom. From a pair of clashing elements, the auto-assignment process selects the discipline of the less important element to be the owner of the clash, that is, the element with the class that is nearer to the top of the list.

The Description field is for specifying the text to appear as the report column header for the attribute values.

The Attribute box enables the attribute associated with the selected class attribute value to be specified. Clash Manager will search for the attribute on the clashing item, and if not found there, will search the owning hierarchy for it.

Note:
If Not Used is selected, the CLASS attribute does not appear in the Clash Manager UI. CLASS is designed to produce a modest number of look-up records, when a value is used as a wildcard. An attribute, such as a NAME that would return a large number of values should not be used.

To automatically produces a list of class descriptions and attributes that are applicable to elements in clashes that have been discovered by Clash Manager, select Discover.

Each description of the various classes is formed by a concatenation of the attribute name followed by the particular attribute value. For example, for an attribute type and a value BEND, the description is type BEND. Each listed attribute value is available as a Regular Expression wildcard (refer to Notes on Wildcards for further information) for use in assignment and acceptance rules. The values are preceded by ^ and followed by $ to make sure that only complete strings are matched, for example, ^BEND$.
