This command creates a closed polyline which encloses a given set of point and linework entities. The resulting polyline is created in the specified layer.
There are two different methods. The Across Gaps method creates
a closed polyline through the points around the perimeter of the
area defined by the selected entities. The Max Gap limits how far
the polyline segments will connect between points. The Perimeter
Reduction pulls in the shrink-wrap polyline to make a tighter fit
similar to a vacuum suction effect. The 3D Polyline method uses the
elevations of the input entities to create a 3D polyline. The 2D
Polyline method ignores the elevations of the input entities and
creates a polyline at elevation zero. For open polylines, as in the
bottom figure, the Gap method works better, as it jumps across the
gaps and connects the end points. The Interior Void method creates
a closed boundary polyline for an empty area that is surrounded by
points such as a pond. The Ignore Zero Elevations option will
filter out entities at zero elevation and not use them in creating
the perimeter. The Elevate Zero Elevations option will interpolate
zero elevation vertices in the perimeter polyline using other
vertices with elevations.
For the Bounded Linework Only method, the shrink-wrap polyline
follows the outside border of the selected polylines. The polylines
that are processed have to be connected to be shrink-wrapped. The
Snap Tolerance is the maximum gap that will be joined to make the
closed polyline.
