House Graphics

Want to know what a good 3D graphics program is for building houses.
Particuarly one with the sun and shadows. , and is relatively easy to use or learn and is professional?

I would recommend Bentley Microstation. If you've used before DAC, it is a simple jump. I first used this in my college courses in architecture - and now a student edition was available for a discount * * significant compared to the price engineer.

Professionally, I also used 3D Studio-a bit - because it always interacts with DXF import (although you must always manually create your 3D extrusion).

Each of these would be good choices, esp. If you want to use these professionals.
