Replace/load sheet background
Operation possible on drawings. 
This operation replaces the background of one or more sheets in the drawing.
Select the sheet number from the list. The number must be a numeric value. You can enter it using the keyboard or the drop-down list:
Example: The sheet background for sheet " 5 " will be replaced with the sheet background " …\SOLIDWORKS 2017\lang\french\sheetformat\a3 - iso.slddrt ".
Instead of specifying a sheet, you can use the character ''*'' to replace the background of all sheets.
If you want to replace multiple sheets, use the character ''; '' as a separator.
