Selecting the Define from shape from the Fence tab on the Print Styles dialog opens the Define from shape dialog. This dialog allows you to define the attributes of shapes whose actual coordinates define the print area.

In the Search section, clear the Master model or Reference files check box to limit the search for boundary-defining shapes. By default, Print Organizer searches each master model and all of its references to find the boundary-defining shape. You can restrict the search to specific references by typing their logical names (for example: "border") or filenames (without drives or folders, for example, "border.dgn") in the Reference files list box. The reference filenames may be regular expressions.

In the Shape properties section, you can restrict the search to specific levels by typing the level names into the Levels list box. As with references, level names can be regular expressions. The Colors (0–255), Weights (0–31), and Styles (0–7) fields limit the search to a specific color, weight, or style. Each field accepts single integer values, dash-separated ranges of integer values, and comma-separated lists of values and ranges. Example: 1, 2, 3, 5-7.

The "Create one print definition from first matching shape" specifies that the first matching shape be used to define the print area, and the "Create one print definition for each matching shape" specifies that one print be created from each shape. The configuration variable MS_PLT_AUTOAREA_RESULT_LIMIT defines the maximum number of print definitions to be created when searching for multiple shapes or cells. The default limit is 500.
