Specify General Options for DWG/DXF Export

Use the General tab of the Modify DWG/DXF Export Setup dialog to specify settings for export to DWG and DXF.

Room and area boundaries

Select this option if you want rooms and areas to be exported to a DWG or DXF file as closed polylines.

• Area polylines are generated from area plan views only. See Area Analysis.
• Room polylines are generated from floor plan views or ceiling plan views only. See Rooms.

Note: For Revit MEP, this option also applies to spaces.

For rooms, the exported polylines match the boundaries of rooms in Revit. The room boundaries are exported onto a single layer, and that layer is turned off by default in the DWG file. The polylines include the following XDATA information for room boundaries: Name, Number, Occupancy, Occupant, Department, and Comments.

For areas, the polylines include the following information for area boundaries: Name and Comments.

Note: These room and area features are primarily intended for Revit Architecture and Revit MEP users.

Non-plottable layers

Select the Make layers containing the following text not plottable option to mark as non-plottable any layers whose names contain the specified text. Note that the text box is inactive if the option is cleared.

Options

• Hide scope boxes: Select this option to hide scope boxes in the exported file. Clear the option to include scope boxes.
• Hide reference planes: Select this option to hide reference planes in the exported file. Clear the option to include reference planes.
• Hide unreferenced view tags: Select this option to hide unreferenced view tags in the exported file. Clear the option to include unreferenced view tags.
• Preserve coincident lines: Select this option to include coincident lines in the exported file. Clear the option to omit them. See About Exporting Models with Coincident Lines.
  Note: This feature or functionality is available only to students and to Autodesk Maintenance and Desktop Subscription customers for Revit 2015 software releases.

Default export options

If you want any Revit or DWG links in the project to be exported to a single file rather than to several files that reference each other, make sure the Export views on sheets and links as external references option is cleared. This setting establishes the default setting in the Export CAD Formats dialog when you export using this setup.

For the Export to file format option, select the desired AutoCAD format from the drop-down list. The selected format will be the default format displayed in the Export CAD Formats dialog when you export using this setup.

Note: When the selected option is AutoCAD 2000 Format, layer names are limited to 32 characters. Revit automatically truncates longer names, retaining the first 15 characters and the last 15 characters, separated by an underbar character (_) and suffixed with a unique numeric character.
