    How To: Export an Image with Only Shadows (Cast or Ambient)

    This question came up when a designer in our office wanted just a Shadow Layer for her rendering to use in Photoshop. This isn't an OOTB feature Revit provides and I was surprised to find that even after some searching I couldn't find an answer. Turns out its actually pretty easy!

    The first thing I did was duplicate the view. To setup the new image use the Hidden Line Style in the Graphic Display Options and have both Silhouettes and Background both turned off.

    I'm showing just a portion of the model here which has Linework, Ambient Shadows, and Cast Shadows all visible.

    Make a selection box and highlight everything, then right-click to open up the Override Graphics in View > By Element. Hide Linework and Surfaces by turning them white to match the background.

    and that's it! Toggle between Cast or Ambient shadows just by turning them on or off in the Graphic Display. Use File > Export Image to save the images.
