Use this procedure to import a sheet into the project sheet set.
When you import a layout as a sheet, the layout and its associated sheet drawing are physically not moved from their original location. For example, if you import a layout from the drawing C:\Additional Drawings\Example.dwg into the project sheet subset Architectural, the selected sheet is displayed under the Architectural subset; the Example.dwg file, however, is not moved into the Sheets folder of the project. This drawing remains in its original location under C:\Additional Drawings\Example.dwg.
If you switch to the Explorer View, the imported sheet drawing is listed if the drawing is located outside the folder. It is marked with a special icon .
A sheet can belong to only one sheet set. You cannot import a sheet that is already part of another sheet set.
