■ Select DESC1DESC2, and DESC3.
■ Drag the attributes into the Block Editor.
■ Select an insertion point at approximately -0.8125,0.3125.

Note: The insertion point of multiple attributes is based on the insertion point of the attributes in the attribute template being used.



21:  Insert Wire Connections:

In the Attribute Editor, under Wire Connection, from the Direction/Style list, select Left/None.



22:  Click Insert Wire Connection.



23:  In the Block Editor, insert the wire connection attribute exactly at the left corner of your symbol. Be sure to use some kind of Snap mode. Press ENTER.
