I've tryed to render in Cad 2009, but every time start rendering, when it finish instead to show the picture, it shows me a black screen, did I missed something? I already place the materials on each object.
Could you please give me a little push.

you should fix your viewport.. i think you are rendering the wrong viewport.

Try to put some lights into your scene.

Change the Color of object's layer.

The reason why the object when I started to renderize comes with black screen was because the drawing was to close, I had to zoom out a little bit and I started renderizing and it works perfect.
