Custom Rules can be created by selecting “...” next to the rule name dropdown, as shown above.
To create a new Rule:
TIP: Add a "*" to make your favorite Rule first in the list. When Exporting this rule, it is recommended to exclude the “*” character from the Rule file name .
Next, set the values for the Target Parameter and (optional) Ignore Parameter.
The list of available parameters is based upon the text-based parameters defined in the project and assigned to the data Category of the Rule. For example, a Data Device Rule will have Comments and Mark as available choices, along with any other custom text-based parameters you have defined within the project.
The Ignore Parameter is an optional Rule setting that can be used to ensure that certain elements are always ignored during a numbering process. The list of available parameters is limited to only those parameters that are of the "Yes/No" type. A Project parameter called "IgnoreInstance", for example, could be created as a "Yes/No" parameter and used to ensure that certain Spaces are never included in numbering. A Project or Family parameter called "IgnoreType", for example, could be used as a way to ensure that all access, elevator or bathroom partition doors are excluded from numbering.
If a Rule does not have an assigned "Ignore Parameter", then the elements can be manually ignored during a numbering process by selecting the "Element is ignored" checkbox within the Preview Results dialog. In this scenario, however, the setting is not retained and would need to be manually re-set for any future numbering task.
