Why is it that when I raytrace my simple model, some of the surfaces that are absolutely true flat planes have shaded tone lines across them that causes a barrel shape appearance?

I don't know why your response to me showed up in my email, but not on the forum.
When I want a good 3d product for presentation purposes, I use "export to 3ds" from DataCAD and then used Kerkythea 2008 (you can find it online-but needs to be the 2008 version) and then import the 3ds file, add one or more lights and adjust colors and textures as you wish for very nice, but quick images.
