I want to add a decorative crown molding to my rooms. How can I do this?

Crown molding is not included in all of the template styles by default, however, you can set up your defaults so that when you create a new room, crown molding will be automatically placed.
, expand the Floors and Rooms category, expand the Floor Levels subcategory, select the Floor you'd like to modify, then click Edit.

Now, any new rooms you create in this plan will have the Crown Molding you have specified. As mentioned above, you can also add different molding profiles to individual rooms if you desire. This is recommended for any rooms that have already been established in the current project.
