Creating and Editing Polylines In-Depth
This section covers the Polygon node’s capabilities in depth.
The Polyline Toolbar
Whenever a node that contains one or more polylines is selected, the polyline is shown on all
viewers and the Polyline toolbar is displayed along the side of each viewer. The toolbar
contains several buttons that make switching polyline modes and options easy to access.
The Polyline toolbar.
If you hover the pointer over any of the Polyline toolbar buttons, a tooltip that describes the
button’s function appears. Clicking on a button will affect the currently active polyline or the
selected polyline points, depending on the button.
You can change the size of the toolbar icons, add labels to the buttons, or make other
adjustments to the toolbar’s appearance in order to make polylines easier to use. All the
options can by found by right-clicking on the toolbar and selecting from the options displayed in
the contextual menu.
Selecting a Specific Polyline
It is possible to have several polylines in the viewer at once if you select multiple Mask nodes in
the Node Editor, so it’s important to be able to switch between polylines easily.
To make a polyline active, do one of the following:
 Click one of the polyline’s control points or segments.
 Press Tab and Shift-Tab to cycle between available polylines.
 Right-click in the viewer and choose the desired polyline by name from the Controls >
Select menu.
Polyline Creation Modes
There are several different modes available from the toolbar for creating and modifying
polylines. The specific mode used when a polyline is first added will depend on whether it is
used as a path or a mask.
Each of the modes is described in more detail below.
Click Append
This mode is the default mode for mask creation. It’s used to quickly define the rough shape of
the mask, after which you switch to Insert and Modify mode to refine the mask further.
The Click Append toolbar button (Shift-C).
