Lot or Parcel traverses are special traverses that close on themselves.  TPC calls these closed loop traverses, after the closure type. In this help topics, we'll refer to these as Lots.

Area Types

Lot areas are determined by a corresponding Distance Type. The area computed always matches the distance type.

In the case of a traverse, this is the distance type of the traverse.

In the case of a drawing, this is the distance type of the drawing.

Closure View

The Closure View displays the area of Lots in square units (feet or meters) and area units (acres or hectares). The area of a closed loop is computed from the Initial Point to the Closing Point. If these points do not have the same coordinates (the loop doesn't close), TPC connects the two points with an imaginary line and computes the resulting area of the loop.

Each time you open the Closure View and also when you choose View | Refresh, TPC recomputes the area of the Lot.

Lot Labels

Within Drawing and Traverse Drawing Settings, you can turn on lot labels that include the name and area of the Lot.

These lot areas can be computed automatically (slows down the regen process) or manually. To turn on automatic area computations choose Edit | Drawing Settings, Miscellaneous and turn on the [X] Compute Area toggle.

Legal Descriptions

When you create a legal descriptions for Lots.

Predetermined Areas

TPC can create a traverse of some specified area from any Lot. You use the Predetermined Area dialog to specify the area you want and the method to use. TPC creates a new traverse of the area specified and can place the reminding area in another traverse.

Drawing View

By default, Drawing View uses the last area computed for a traverse. If a traverse area has not yet been computed, Drawing View will compute it, then display it.

If you are editing the area of a traverse frequently and want Drawing View to compute the current area,
