Units and Coordinates for DWG/DXF Export

On the Units & Coordinates tab of the Modify DWG/DXF Export Setup dialog (see Exporting to DWG or DXF), you specify the following for the selected export setup:

• One DWG unit is: For imperial projects, the default unit is inches. For metric projects, the default unit is meters.
• Coordinate system basis: Select one of the following options to indicate whether the exported file will use the internal coordinates of the Vasari project, or coordinates that are shared with other linked models.

  Project internal. Sets the origin of the exported file to the internal coordinates of the Vasari project. Use this option when the Vasari project is a stand-alone project that is not linked to other models, or when its particular position is irrelevant for the intended use of the exported file.

  Shared. Sets the origin (0,0,0) of the exported file to the shared position of the Vasari project. All geometry is exported relative to the shared coordinates. Use this option when you want to maintain the specific position of the project being exported.

  When exporting to DWG, it is necessary to specify views and not sheets for shared coordinates to work correctly.
