In TPC, traverse closure and checking closure refers to how well a traverse closes on a known point and any errors involved in that closure, but it also refers to information about that traverse at that time, like it's length and area.
As you edit a traverse, it's closure information is free to change. So TPC thinks of traverse closure as a snapshot in time.
Traverse closure is displayed in the Closure View, which always displays the current status of the traverse. If you have not yet applied any adjustments, it displays the raw closure, area and length. If you balance coordinates, the Closure View will display the balanced closure, area and length.
The Closure View handles all the traverse summary and adjustment functions of TPC. To open the Closure View, open the Traverse View for the traverse you are interested in, then choose the Closure View command.
