To Add or Replace a Format in an Existing Drawing
Creo Parametric stores drawing formats in a separate file. To use one with a drawing, it must be located in the same directory as the drawing. You can change the current drawing size using Format.
1. Click Layout > Sheet Setup. The Sheet Setup dialog box opens.
2. Click Sheet.
3. Click Format and select a standard or variable size format from the list.
4. Click OK.
