Predetermined Area
&RJR 3UHGHWHUPLQHG $UHD 
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.
7DS 3RO\OLQH« : allows you to tap an existing polyline from a map
view to define the fixed sides of the boundary.
Note: a boundary has two fixed sides and one side defined by a
direction when using the Hinge Method. It has
one fixed side and two sides defined by a
direction when using the Parallel Method.
(GLWRU« : accesses the Polyline Editor (Page R-
45) where a new polyline can be created or an
existing polyline can be modified.
7DS 3RLQWV« : provides a map view where you
can tap any existing points to define the fixed
sides of the boundary.
