shadows from elements above cutting plane?

[Anonymous]

Hi,

New to archicad and I would like to render a sun study of a floor plan. I have been using the 3D Cutting Plane to clip the roof from the building to get a look inside from above. Unfortunately this means that the shadows in the PhotoRender Projection are cast as if the building has an open top. The intention of the sun study is to see the penetration of sunlight given the roof overhangs, in a plan view.

See image - the roof is above the cut plane but doesn't cast a shadow

Thanks for any suggestions...
