Error shows in the command line when I try to zoom in, zoom out, or free orbit

[Seeler401]

When working with a 3D drawing in AutoCAD Civil 3D, and have my visual style set to anything but 2D wireframe I get the following error, and my drawing lags and slows down. This happens every time I try to zoom in, zoom out, or free orbit.

Modeling Operation Error:

                Attempt to evaluate a cone with zero major axis.

Failed to calculate silhouettes of a face.

Any Ideas what is causing this and how to fix it??

I'm guess there's a solid cone in the drawing with a major axis of 0. Right click, choose quick select then select the cones in the drawing and remove it or add major axis width. http://screencast.com/t/NBQmqFj1HmI

When I go to the quick select window, choose 3D Solid, there is no Solid Type in the properties scroll down..... Not sure how else to select the cone since I don't see them in the drawing.
