I would like to shade VAV boxes, air terminals, ducts, etc

I think I can do ducts with color scheme but how do I shade mech equipment and air terminals

You should use View Filters to accomplish that. Using these, you can set specific graphical override (visibility, lines, patterns) to all elements that meet the conditions of the defined Filter Rules. Just reply if you need any more information...

Thanks!  Workign on a auto sizing return grille now once done I will test your method and write back either way.

Cheers,
