Unfortunatelly this is an old bug in AutoCAD...
When activating Top View, Grid disappears and Snap is no more aligned. We can temporarily solve this issue by typing UCS and selecting World. But as soon as we change again to 3D View and back to Top View, same issue appears. 
Do the following to solve this permanently...

We cannot imagine our work without using computers anymore, but on the other hand, sometimes they can also give us very hard time. A certain software bug is a real “nerve eater”. And no software is immune to it. So, also in AutoCAD we find these annoying bugs! One of them can move solid object away from its grips! That means, grips are on the right place, but the object seems to be blown out in space. If we have more of such objects, then the drawing really looks “exploded”.

Maybe you haven't tried rendering in AutoCAD, but it can give pretty cool results. Since AutoCAD 2007 the well-known Mental Ray render engine is built in AutoCAD. It is the same render engine as in 3ds max (if you do not change it there to even more popular V-Ray). It means, that AutoCAD render capabilities are quite strong, but on the other hand, not so simple to set up.
