Identify Predefined
Boundaries identifies any polylines in the drawing that have
been previously tagged as Predefined Boundaries. The
Pick option prompts to
pick a polyline, and if it has been tagged as a Predefined
Boundary, the Boundary Type and Boundary Name are presented at the
command line. The Search
option scans the entire drawing for Tagged Predefined Boundaries,
highlights them in the drawing, and lists their location, layer,
type and name at the command line.
Predefined Boundaries are applied in Surface commands such as
Two Surface Volumes and Triangulate &
Contour. Inclusion polylines limit processing to inside
the polyline(s); e.g., an inclusion polyline for volumes would be
the limit of disturbed area. Exclusion polylines prevent processing
inside the polyline; e.g., a building perimeter or pond shoreline
could be an exclusion polyline for contouring. Identifying
polylines that have been previously tagged as Predefined Boundaries
is often helpful during surface modeling.
