/* Polyline Tool */
# Click anywhere on the active work plane to create nodes. The Polyline's contour is rendered as soon as the second node is defined. A Polyline must have at least two nodes.
# The Polyline can be closed at any time by either double-clicking on the workplane to establish a closing node, or by pressing the '''C''' or '''ENTER''' key, which connects the last drawn node with the first.
NOTES, SPECIAL CASES OR EXCEPTIONS: If the polyline shape was originally drawn unclosed, you can place a checkmark in the '''Close''' option box to connect the first drawn anchor point with the last drawn anchor point. Closing the "loop" allows you to fill the polyline shape, creating a planar object whose perimeter and surface area matches the drawn polyline's outline.
'''Index''' reports the unique order number of the currently selected node. '''Active Node''' shows the X, Y and Z coordinates of the currently selected node.
