Creating and Deleting Representation Rules

The upper part of the Representation Rules form shows the name of the current RPLB.

1. You can switch to another RPLB by selecting it in the Members List and pressing the CE button.

   

2. The Rule Sets drop-down list allows you to switch to any RRST owned by the current RPLB.

   The Rules list shows all RRULs in the current RRST.

Specifying the Owning Rule Set

• Select the RRST whose member RRULs you wish to modify from the Rule Set drop-down list.

  The RRULs owned by the current RRST will be shown in the Rule list (or None if you have just created the RRST).

Creating a Rule

• To create a new RRUL, click the Create button and give the new RRUL a name.

  The name will be added to the list and will be highlighted as the current selection.

Deleting a Rule

• To delete a RRUL from the current RRST, highlight it in the Rules list and click the Delete button.

Specifying the Elements to which Rules Apply

You can specify the type of element or a list of named elements, as follows:

3. To specify the type of element to which the current RRUL is to be applied, click the For option button and select the type from the drop-down list.

4. To specify named elements to which the current RRUL is to be applied, press the Modify button, and the Names form will be displayed.

5. On this form, select individual elements from the Members list for copying to the Names list in the usual way.

6. When you press OK, the names will be shown in the text pane on the Representation Rules form.

Criteria for Rule Application

7. To apply qualifying restrictions to the elements specified by the For option, type an expression in the With text box.

   For example, if the For gadget specifies Branches, you might use the With qualifier to enter:

   ’(HBOR GT 100) AND (TBOR GT 80)’

   The above means ‘Branches with HBOR greater than 100 mm and TBOR greater than 80 mm’.

8. The Symbology checkbox, if checked, requires the Design items to be represented symbolically.

   Refer to the Draft User Guide for further information on 2D Symbolic Representation and Representation Rules for 2D Symbology.

   The Style box halfway down the form, shows the name of the STYL (if set) that is referenced by the current RRUL. The way in which you set this is explained in Associating Representation Rules with Styles.
