Arranging One Mesh Over Plane Mesh I created a plane mesh (ground) and then another mesh (tree).

On right view, it seems like this:



However on top view, the tree doesn't seem there. I also tried boosting the z-value but it doesn't come on top of ground any how. (But for right view, it goes high if I change the z).



Also when I start tilting a little in the right view, It becomes like these:  

And in render, it creates an unexpected shade on the tree which I believe the above problem is causing.
The unexpected shading could either be flipped normals, or a lack of lighting. You could try turning on "Ambient Occlusion" in the display settings tab to help you be able to see the tree in top-down mode. It's not showing because it's the same color as the groun.
