The 2009 tutorials have a section on design options. In fact the example is
different roof/trellis options for a design.

Chapter 21, pg. 745 is where the section on design options begins.

i want to create several roof options for a house. i know you can do that
through design options but have been unable to find a tutorial or any
explanation as to how to use this feature. i've been able to set up the
different options, but need to know how to change the option my existing
roof is associated with. then i'm assuming i can start to draw the other
roofs within their associated option. help?
