A polyline is a continuous sequence of lines and arcs that constitutes a single entity. There are three commands to create polylines. The RECTANGLE and
POLYGON commands that we saw in Chapter 3, Starting to Create Projects, and the RING command that we will see later in this chapter also creates polylines but with specific shapes.
Note
Polylines are very useful when we need to calculate areas and lengths on the project, and for distributing points or components evenly spaced or at measured intervals, along its length.
The POLYLINE command (alias PL,
