On a dieboard, bridges are the objects that hold the rules fixed firmly onto the board and prevent the dieboard from disintegrating after the dieboard has been cut. Bridges can be edited, moved across a rule or deleted from it.
In a drawing, bridges appear as holes. These are discrete objects with properties of their own.
In a bridges drawing, the following buttons are available for editing on the Diemaking tab.
New Bridges Drawing
Show/Hide Closed Regions (Available in a bridges drawing.) Displays, by hatching, if there are any closed contours.
Place bridges (Available in a Bridges drawing) Opens a dialog box in which the automatic bridge-placement settings are made.
Place Bridges Manually (Available in a bridges drawing.) Launches the mode in which you can place bridges with the mouse: clicking where you want a bridge placed.
Replace Gaps Opens a dialog box in which the conditions for the replacement of gaps are set.
Manual Replace Gaps (Available in a bridges drawing) Launches the mode in which gaps in a bridges drawing are replaced manually.
Place Nicks Launches the mode for positioning nicks.
Place Multiple Nicks Launches the mode for positioning nicks.
New Rules Drawing
Select Bridges (Available in bridges drawings) Launches a variant of the select mode in which you can select the bridges.
NOTE: In this mode you cannot select any other objects in the drawing.
Bridges are managed in a separate drawing, which is inherited from the layout drawing. If changes are made to the original 1up design or to the layout drawing, these changes are reflected also in the Bridges drawing by refreshing the view. (Clicking Refresh Drawing 
.) Learn more about how to create bridges drawings.
NOTE: In a project, there can be only one bridges drawing.
Bridges' properties can be viewed in Package Designer's tabular area.
In the tabular area, a bridge is identified by its name (Name), the object on whichit is placed (Object), its length (Length) and, in percentage, its position (Position).
You can edit the properties of a bridge EngView its name, length and position. This can take place in both the graphical and the tabular areas. You can alter a bridge's position along the rule it is placed on by using the mouse and move the bridge along. NOTE: This lets you change only the position of the bridge, not its length.
