A classification definition is a group of named properties or characteristics that you can assign to building objects such as walls and doors. Classifications enable you to track objects by construction status, project phase, building element, vendor, or other criteria. A classification definition is applied to an object type. The definition contains classification names and descriptions. Each classification can have property sets attached to it.
Classifications and Schedule Tables
Classifications provide additional control over the content of schedule tables. You can include:
- only those objects that meet the classification criteria.
- classification definitions as columns.
- additional information from property sets you create and attach to individual classifications.
Uses for Classifications
Here are some examples of classification definitions:
- Classifications for multi-view blocks enable you to distinguish among blocks to use for furniture, appliances, fixtures, and equipment
- Classifications for project phases can call out changes specified for new or demolition work and existing structure to remain
- Classifications for door types let you filter partition doors in bathrooms from door schedules
Classifications and the Display System
You can modify display sets in a display configuration to show or hide objects based on their classification.
Managing Classification Definitions
Classifications are organized in a hierarchical view in the Style Manager. Classification names must be unique within classification property definitions. To create, edit, copy, or purge classification definitions, you access the Style Manager. The Style Manager provides a central location for working with definitions and styles from multiple drawings and templates.
After classifications are applied to objects in the classification definition, they display on the Extended Data tab of the Properties palette when the object is selected. You can change the classification for an object from the Extended Data tab in the Select Classification worksheet. If the classification change results in an object not displaying in your drawing window, a warning dialog box displays. You can also open the object style in the Style Manager and make changes on the Classifications tab.
