Predetermined Area
Cogo Predetermined Area .
The Predetermined Area routine will take a boundary with one open
side and compute the location of a line that will enclose the boundary
with a specified area using the Hinge Method or the Parallel Method.
The Hinge Method computes the location of the side of a boundary
that can pivot on a fixed point.
The Parallel Method computes the location of one side of a four-sided
boundary where the computed side is parallel to a stationary side of
the boundary.
The top-left field is used to enter the desired area of the specified
boundary. In the next field, select the units entered from the
dropdown list.
Hinge: solves the boundary using the Hinge Method when selected.
Parallel: solves the boundary using the Parallel Method when
selected.
Tap Polyline… : allows you to tap an existing polyline from a map
view to define the fixed sides of the boundary.
