Coloring Existing Pipe Differently

HydraCAD has a command called Change item Colors. It is found right after Pretty Pipes on the Cleanup toolbar. What does it do? It lets you assign colors to different parts of your drawing. It is run after you run Pretty Pipes, hence it's location on that toolbar.

You can assign three additional colors to Pretty Pipes such as Existing Pipe, Demo Pipe and New Pipe. You can also assign different linetypes to these parts of the drawing as well. The colors and linetypes can be applied to the areas you select or to just one pipe if you want. Sprinkler heads and other objects will change color as well.
