Create and Modify Classifications

To aid in the creation of templates, the drawlist has been modified to use classifications. A classification is a collection of objects gathered according to a defined criterion.

To create a classification:

1. Select Create then Area ADP Library and then Classification to display the ABA Classification Definition form.

   

2. Enter a suitable name for the classification in the Name field.

3. Enter a suitable description for the classification in the Description field.

4. Enter the required criteria in the Criteria field. To modify/replace or remove a criteria select the desired criteria from the list. The criteria may be of two different types.

5. Select Criteria Type. This determines the check on input criteria but depends on the type:

   • Rule ‑ to add (or remove) a certain type of element with an attribute of a specified value (if required). Examples:

     ALL PIPE

     ALL PIPE WITH PSPEC EQ A1A

     Note: Always use a qualifying element with the All statement. Otherwise the time taken to evaluate the expression is excessive. An expression such as ALL WITH (PURP EQ ‘ANY’) is not recommended.

   • Element ‑ to add (or remove) an element from the DESIGN database (the name is normally used, but you can use the reference number). The item may be added manually or by going to the relevant item in the member’s list and clicking on the CE button to the right of the Criteria field.

6. Select the type of rule from the pull down menu (either Add or Remove).

7. Select the action required from the second pull-down menu:

   1. to add an extra criterion to the Criteria List select Add Criteria.

   2. to modify/replace an existing criterion make sure the correct one is selected and select Replace Criteria.

   3. to remove a criterion from the list make sure the correct one is selected and select Remove Criteria.

8. Finally, click the relevant button:

   4. to create a new Classification click Add.

   5. to modify/replace an existing Classification make sure the correct one is selected in the lower pane and click Replace.

   6. to remove an existing Classification make sure the correct one is selected in the lower pane and click Remove.

   Note: Criteria and Classifications may also be deleted by selecting them in the relevant pane, right clicking, and selecting Remove from the pop-up menu.
