Calculate Wireframe Attributes (Expression)
The Wireframe Attributes (Expression) tool has been added to the Wireframe tab, in the Calculations group to allow the use of dynamic expressions to calculate new attribute values from existing properties and attributes.
For more information on the new tool, see Wireframe Attributes (Expression).
Wireframe Attribute Variables
Wireframe attributes are now available as variables for the Attribute Assign | From Block Model tool and can be used in aggregated field expressions.
When multiple input wireframes are selected, only the wireframe attributes common to all the input wireframe types are available. All wireframe attribute values are treated as numeric values (since they need to work for all the aggregation methods).

Wireframe Clean-Up Set Support
The Clean-up (Form) tool on the Wireframe tab, in the Clean-up group now supports wireframe set input.
Both ad hoc and normal wireframe sets can be used, but sets containing more than one Type are not supported.
If the Overwrite input wireframe option is selected for a wireframe Set, all input wireframes are overwritten with their cleaned counterparts. If the option is not selected, the output Name is disabled and new wireframes are created for the output Type with the same name as their inputs.
