This section will describe the Edit Global area and how it is used to edit connectors and application areas. Information on these elements may be found on the Connectors and Application Areas pages respectively.

Edit Connector

When a connector is double-clicked in the Connectors list, it is opened for editing in the Edit Connector area.

• Code: A unique identifier for the connector. Every connector must have its own unique code. If the user attempts to set the code to that of another connector, the creator will make the code unique before the change is applied.
• Is Attach Point: This check box toggles the connector as being an Attach or not. A connector that has been marked as an Attach will not appear on the symbol when it is placed in a drawing. Additionally, the connector will not snap to other connectors when the symbol is being moved about a drawing unless the respective symbol's connection rules allow it.
• Add Attach: Attaches are the set of connectors that the current connector is allowed to attach to. Attaches are references to other connectors, and these references can be added to the connector manually by entering the other connectors’ codes in this field.
• Attaches: This is a list of the Attaches currently assigned to the connector. Attaches can be removed by selecting them, then either pressing the Delete key on the keyboard, or pressing the Remove Attach button below. There are two additional ways to add Attaches to a connector. By dragging a connector from the Connectors list to the Attaches list, that connector’s code will be added as an Attach. Additionally, the arrow button on the left side of the Edit Connector area will add Attaches for all of the connectors that are currently selected in the Connectors list.

Edit Application Area

When an application area is double-clicked in the Application Areas list, it is opened for editing in the Edit Application Area area.

• Code: A unique identifier for the application area. Every application area must have its own unique code. If the user attempts to set a code that already belongs to another application area, the creator will make the code unique before the change is applied.
• Material Reference: A reference to an existing material. The reference can be made manually by typing a code into this field or by dragging the material from the Materials list to this field.
• Surface Ids: This is a list of the layers that the application area should be applied to. Typing a value into the field will add that layer to the list. Layers can be removed from this list by selecting them, then either pressing the Delete key on the keyboard, or pressing the Remove Surface Id(s) button below.
  
  There are two additional ways to add layers to an application area: 
  • Drag a layer from the Layers list to the Surface Ids area to add it to the list. 
  • Press the arrow button along the left side of the area to add all layers currently selected in the Layers list to the Surface Ids list.

Edit External Reference Key

When an External Reference Key is double-clicked in the E-Key list, it is opened for editing in the Edit External Reference Key area.

• Select Type: A list of Existing External Reference key types. A type must be selected in order to create a new External Reference Key.
• Value: Value for the External Reference Key. A value needs to be unique under the same External Reference Key type.
