Exporting to CAD Format Properties
When exporting to a CAD format, you can use the format properties tab on the Export CAD Formats dialog
to specify various options. Each format properties tab is named by its specific format, such as DWG Properties.

DWG, DXF, or DGN. The Export CAD Formats dialog
opens.
2 Click the <Format> Properties tab.
3 Click (Browse) or Layer Settings to access the Export Layers dialog.
From this dialog, you load an existing layer mapping file, create a standard layer mapping file,
or customize layer mappings. For more information, see
Exporting Layers on page 1360.
Layers and Properties
Select a value from the Layers and Properties list to control how to export object styles from Revit Architecture
to AutoCAD (or other CAD applications).
NOTE You can define layers and properties when exporting to DXF or DWG. These options are not available when
exporting to DGN or SAT.
When you export a Revit view to DWG or DXF, each Revit category is mapped to an AutoCAD layer, as
specified in the Export Layer dialog. In AutoCAD, the layer controls the display of the entities (Revit elements),
including their colors, line weights, and line styles. In Revit Architecture, you define object styles in the
Object Styles dialog. (See
Object Styles on page 493.) The Layers and Properties setting determines what
happens to a Revit element if it has attributes (object styles) that differ from those defined for its category.
In AutoCAD and in Revit Architecture, view-specific element graphics are referred to as overrides.
Select one of the following values:
■ Category properties BYLAYER, overrides BYENTITY . When a Revit element with view-specific graphics
is exported, in AutoCAD those differences (overrides) are applied to the individual entity, but the entity
resides on the same layer as other entities in the same Revit category or AutoCAD layer.
■ All properties BYLAYER, no overrides . When a Revit element with view-specific graphics is exported, in
AutoCAD those differences (overrides) are ignored. The entity resides on the same layer as other entities
in the same Revit category or AutoCAD layer, and it loses its unique attributes. This option forces all
entities to follow visual properties as defined by their layer. It produces the least number of layers and
provides by-layer control over the exported DWG file.
