AutoCad 3D :: Surface Boundary Lines Won't Go Away In Animation View

So I've been creating a building and I can't seem to get rid of (or hide) the lines that make up the edges of my surfaces (or solid) in the animation view. Is this typical?

For instance, I have one side of the building that is using 4 different textures all on the same plane and they butt up to one another (example: brick meets siding). Where these two surfaces meet the lines that makes up the edges of the surface won't go away. Thus always showing white line showing the boundaries o the individual surfaces.

Can I turn these off, hide them, or am I being a total 3D Modeling noob and missing something basic?
