Hi Ahmed,

If you have set it correctly in the 3d window settings, then the shadows should show after you have pressed esc to stop navigating in the 3d window. They don't show while you are moving around.

Your image looks like you were in the middle of navigating around the model when you took the screenshot as there are no contour lines to your model. Is that correct?

I suppose it could be a graphics card problem if all other setting are correct. Have you updated the drivers recently?

I noticed this in AC14 as well - sometimes the shadows don't show, it may well be a graphics card issue as Peter suggested, but I found restarting Archicad normally solved the problem. I'll try updating my graphics driver and see if there's any change - it was a fairly inconsistent problem though, so not sure if I can duplicate it anyhow.
