Have multiple options you want to try in your building for a particular area, configuration of spaces, elevation, etc. Use a design option. You can model each piece that you want to do separately, and have it show whatever option you want in whatever view (you can also schedule and tag items). If you want to change to one of your different options, no problem, just select a different one in the drop down box. Decide on an option? You can get rid of all the other ones and insert the winning design into the model with the click of one button! Yay!
