Irrigation Heads. The irrigation head tool is used to place your sprinklers. This tool creates a 2D object that shows the head and spray pattern. It does not create a 3D version, although with Vectorworks 2010 you can see the spray pattern in 3D, but only if you layer plane.
Because the object is 2D only, you can’t use the Send to Surface command to see the irrigation head on your site model, the planar graphics always have the spray pattern on the bottom of the layer.
In earlier versions of Vectorworks the spray pattern is 2D only, and you can not change it.
