In the DWG Publish dialog, if the desired setup is not listed under Select Export Setup, select a different one from the drop-down list. To modify the selected setup or create a new one, click (Modify Export Setup); otherwise, skip to step 4.
The left panel of the Modify DWG/DXF Export Setup dialog lists all existing export setups. Settings for the currently selected setup display on the tabs. Use the following controls to manage setups:
New Export Setup. Uses default settings.
Duplicate Export Setup. Creates new setup using settings from the currently selected setup.
Rename Export Setup. Prompts you to specify new name for currently selected setup.
Delete Export Setup. Deletes the selected setups (except for the default <in session export setup> which cannot be deleted).
In the Modify DWG/DXF Export Setup dialog, specify export options as needed on the following tabs:
Enter a name, or accept the default name, for the exported file.
For Files of type, select an AutoCAD version for the published DWG file.
For Naming, select an option for the automatically generated file name.
If you want any Revit LT or DWG links in the project to be published to a single file rather than to several files that reference each other, make sure the Xref views on sheets and links as external references option is cleared. (The default setting for this option is specified on the General tab of the Modify DWG/DXF Export Settings dialog referenced in step 3.)
Revit LT generates a DWG file and posts it on the specified Autodesk® Buzzsaw site.
