Define Range of Element’s Projected Display (Show Projection)

The Show Projection pop-up provides options for setting the range within which a multi-story element (Wall, Curtain Wall, Column, Beam, Roof) should be displayed. This control is therefore only available if the element’s Floor Plan Display is set (using the Floor Plan Display pop-up) to either “Projected” or “Projected with Overhead.”
Entire Element (default setting): The element will be displayed on all relevant stories.
To Floor Plan Range: Choose to show the element on a range of stories (the current story, plus a given number of stories above and below it, and an optional offset.)
By Absolute Display Limit: Set a fixed lower limit (by default, this is Project Zero), then show all parts of the element above this limit.
