Shadow in shaded view ortho view, is it possible?

Hi,



whilst perspective view shaded view gives indication of structures, in ortho view I could do with some faint shadow cast down from the cross beam, and something to differentiate the vertical side beams and underside and top beams from the end !

Can ortho view have shadows cast ?

Also the joints between the wood instead of being pale on the end view I could do with being darker, …

What settings do I need to alter these two ?
