Thank for reply. I created a local light as you said and I get the ground shadow. But I wonder why:
- The "Grey room" lighting style has it own shadow, why this shadow doesn't appear so we must creat new local light.
- The ground shadow show in rendered picture (I think it is shadow of local light) is different from "preview" in model view (may be it's the shadow of "Grey room"). So we can't preview result before render.
Yeah, i think Inventor is a bit misleading in that part.
Look at the tooltip in this screenshot for the shadow settings:

These are settings that only affect the "preview rendering", which i understand/suspect to be the viewport shadows.
So "Grey Room" doesn't really have a shadow of it's own, it's a global light that can only cast diffuse shadow.
(which you could see in your first screenshot)
The ground shadow in your render is indeed from the local light, the way it looks depends on how you position the light.
You are correct in that you do not get a preview of this shadow until you render, which isn't very user friendly.
A sort of workaround would be to set your render settings to a low quality and only a few iterations in order to create a quick preview, but you'll have to go back & forth between the light settings and rendering in order to get the shadows where and how you want them.
