How do I show high level items in floor plans?

This post is regarding one particular query, you can see the full list by clicking here.

The elements that are displayed in a floor plan are determined by the View Range. Most importantly, anything below the level of the Cut Plane is drawn. Items that intersect this level are shown as being Cut (note: some families will display in their entirety even if only a small bit intersects the Cut Plane. More on that here).

If you have high elements such as high-cill strip windows, you may need to raise the cut plane in order to show these. However, you may find that it needs to be very high for some elements but lower in most other cases. If this is the case you can use Plan Regions to define areas of differing View Range levels.

To do so, select the Plan Views drop-down in the Views Tab on the Ribbon and then select Plan Region (Views>Plan Views>Plan Region). Draw the Plan Region over the area where the View Range needs to be different. Select this Region and in the Properties Window, change the View Range.

A nice and simple description of the View Range can be found here.
