Polylines
Lines can be added to your project that can represent anything such
as a roadway, a building, or a lot boundary. These lines are referred
to as polylines. Polylines can be compared to the point lists used in
other TDS data collection software. They can consist of several
individual curved and straight sections. A point must be stored in the
project for all the locations on the polyline where a new section begins
and ends.
Polylines can be used to compute information such as the perimeter
and area for a lot boundary. They can also make it easier to compute
and store offset points for the sides of a roadway when a polyline
exists that defines a roadway centerline.
Refer to the Reference Manual for information on all the screens that
are used to create and edit polylines.
