PolylineModel

The PolylineModel is used to determine the graphics for polyline type objects that appear as a single‑segment or multi‑segment line, such as Polyline, Arrow, EntityConveyor, and EntityDelay.  It cannot be used by other objects such as a DisplayEntity intended for 3D or 2D graphics.

The inputs to the PolylineModel keywords set the default values for the corresponding keywords for Polyline, Arrow, etc.  A PolylineModel can therefore be used as a style for these objects.  For example, changing the LineColour input for a PolylineModel will change the colour of the line shown by all the objects that use that PolylineModel as their DisplayModel input.
