Skylights
To add to John's advice, if you do this a lot, and would prefer not to have to do a lot of object-level overrides or, if you need to have both "vertical" Windows and "skylight" Windows use the Model Display Representation for non-orthographic views, you may want to duplicate the Model Display Representation for Windows and give it a name like Model Skylight (any name will do; pick something that will be meaningful to you and describe your intended use). Then you can leave the Model Display Representation as is, while adding the Model Skylight Display Representation to your plan view Display Representation Set(s). You can then set style-level overrides on your "vertical" Window styles for the Model Skylight Display Representation and turn off all of the components (since you just want to see the plan Display Representation for these Windows) and on your "skylight" Window styles, you can set a style-level override on whatever plan and sill Display Representations you use and turn off all of those components, so that the skylight Window styles only show the Model Skylight Display Representation components in the plan Display Representation Set. That will also let you customize the Model Skylight display as desired, without messing with the Model Display Representation.
