A polyline is a series of straight lines at different angles
joined end to end.
The default formatting and Format
Dialog for polyline are the same as for other elements (see Section
3.1.3). Please note that by default,
polyline is handled as an atomic shape. If you want to access and change
individual breakpoints, select
Edit Points from the polyline pop-up menu
to enter point editing mode (see below).
A polyline is always created as an open shape, but you can
later make it closed by checking
Closed from the pop-up menu. To make it
open again, uncheck the
Closed pop-up menu element. When a polyline is
closed, it can have a fill color in addition to its line color. To set the fill
color, open the Format Dialog for the polyline and select the color in
Color field in the
Fill section of
Line and Fill tab.
Please note that the
Fill section is enabled only when the polyline is
closed.
When you are editing points along a line, you will see a
control handle for each breakpoint and at either end. You can add points by
dragging from somewhere on a line segment, or delete them by Ctrl-clicking them.
These operations are also available from the pop-up menu of the line segments
and points in this mode. To exit point editing mode, just click away from the
line to deselect it, or select
Exit Edit Points from the pop-up
menu.
