About Off-page Connectors (OPCs)

Off-page connectors maintain the continuity of lines that span drawings.

They are used in pairs: in the originating drawing and in the connected drawing. A line leaving a drawing requires a To connector. The same line in the second drawing requires a From connector. Both are represented by the same symbol and both have the same connector number to identify the continuity.

You can tell at a glance whether a connector is disconnected, connected, or connected but with mismatched properties. The appropriate status icon appears next to the connector:

Note: Only a connector that is attached to an SLINE has a status icon.

Keep in mind the following:

• If you right-click a connector and click Properties, you can enter the Connector Number (10115 for example) and Origin or Destination (FROM T - 100 and TO E - 200), for example).
• The drawing number, unlike the connector number, is a drawing property. If you right-click the drawing name in the Project Manager and click Properties, you can enter a DWG Number. The appropriate Connected TO and Connected FROM Drawing Numbers are then displayed automatically within the connector when the connection is made.
• You can connect an unassigned line OPC to and assigned line OPC but not the reverse.

Off-page connector (OPC)

Making OPC connections is now easier and more reliable.

When you connect an OPC, only lines that can be connected to are now displayed in the list. Lines that do not have an open connection, or are unassigned are no longer displayed.

You can no longer connect to an unassigned line. This prevents accidentally modifying the line tag in another drawing.
