The Boundary Polyline options allow the user to Set the Boundary
Polyline, Set the Exclusion Polylines, Clear Exclusion Polylines,
Hatch the Boundary Area, Erase the Boundary Hatched area.
Set Boundary Polyline
Use this command to select the "CLOSED" polyline that defines the
outer most limit of the disturbed area. This boundary should
dissect the site at the point where the design contours meet the
existing contours, or where the limit of work will occur. If your
site contains separated areas (such as different phases or isolated
sections of work), then multiple Boundary Polylines can be used.
Volume calculation will take place inside this boundary.
Prerequisite: a closed polyline Keyboard Command: tag_inclu
Set Exclusion Polylines
Use this command to select the "CLOSED" polylines the define the
areas inside the Boundary Polyline that will not be disturbed.
These boundaries should also be at the intersection of the proposed
and existing surface. A pond or wetland that will not be removed
during construction is a good example of an Exclusion Area.
Prerequisite: a closed polyline Keyboard Command: tag_exclu
Clear Exclusion Polylines
Use this command to select polylines that were previously defined
as exclusion polylines but are no longer needed as exclusion
areas.
This command highlights the polyline you set as the Boundary
Polyline.
Prerequisite: a boundary polyline Keyboard Command: highlight_boundary
Hatch Boundary Area

selected are correct. This hatched area can also be utilized in
exhibits of the drawing.
Prerequisite: a boundary polyline Keyboard Command: hatch_boundary
Erase Boundary Hatch
This command erases the hatch drawn in the plan view.
