I have created a surface using 2D and 3D polylines. The 2D polylines with arcs do not define well. They create a straight contour between the ends of the arc. Why is that? And please don't tell me to define it as a 3D polyline. I shouldn't have to create more vertices and make the drawing size huge, then reduce the vertices using another command. These are extra steps the user shouldn't have to perform.

Do you have information near the arc that should cause the surface to be anything other than a flat plane? The entire are is at the same elevation so by default I would expect a contour would be linear between the ends. Maybe experiment with the Densify Breaklines option.
