Omni Class parameter Tool - this will set the Omni parameters for all elements and each parameter fills the element details in the Autodesk® Revit® model and updates. The Omni Space and Room parameter will fill the room description and number for each room and space and room Tag for all Room names. 

Omni Class is a new classification system for the construction industry. All Revit families have parameters for assigning an OmniClass code.

The Revit API defines two built-in parameters for accessing the OmniClass data:

• OMNICLASS_CODE
• OMNICLASS_DESCRIPTION

Select only those elements which have a non-empty OmniClass code. For those elements, the Code and Description are extracted from the element parameters.
