Displays all of the sheets that are found in the DWF file. If the DWF file only contains a single sheet, that sheet is listed. You can select multiple sheets by holding the Shift key or the Ctrl key while selecting the sheets to attach. If you hover over the preview, the file name displays.
Select the full (absolute) path, the relative path to the DWF file, or No Path, the name of the DWF file (the DWF file must be located in the same folder as the current drawing file).
Specifies the insertion point for the selected DWF file. Specify On-Screen is the default. The default insertion point is 0,0,0.
Specifies the scale factor of the selected DWF underlay.
If INSUNITS is set to “unitless” or if the underlay does not contain resolution information, the scale factor becomes the underlay width in AutoCAD units. If INSUNITS has a value such as millimeters, centimeters, inches, or feet, and the underlay has resolution information, the scale factor is applied after the true width of the underlay in AutoCAD units is determined.
