[away3d] Away3d 3.4.0 setup problem

[Kapil]

Hi

I am new to Away3d. I am trying to setup the environment for Away3D
3.4.0 in Flex Builder.

I have created a new ActionScript project. In the ActionScript Build
Path configuration I have added the Away3D folder. In the Project
Properties ActionScript Compiler configuration section, I have
selected Flex SDK 3.5 and Require Flash Player Version is set to
10.0.0.

I am using the following code:

package {
        import away3d.containers.View3D;
        import away3d.primitives.Sphere;
        import flash.display.Sprite;
        public class Basic01 extends Sprite {
                public function Basic01() {
                        var view:View3D = new View3D({x:200,y:200});
                        addChild(view);
                        var sphere:Sphere = new Sphere();
                        view.scene.addChild(sphere);
                        view.render();
                }
        }
}

When I try to build the project I get few erros.

The first error is in the first import statement.
"1172: Definition away3d.containers:View3D could not be found."

Any help is appreciated.
Thanks
