Terrain alternatives

Currently we are using the standard method of terrain - a mapping layer coupled with a texture one. Problem is the topography is far from accurate. We usually get the contours from CAD so they are very accurate, then we need to translate it into raster which less so and into CE which in turn gives really strange results.

I've attached a photo to show how contours (which are on the underlying texture) are quite different from what the terrain is doing. (contours should be flat on the surface as are supposed to be equal-elevation)

Is there a way to use the innately accurate CAD contours instead of a map layer ? We can also convert that into a surface via Civil / Sketchup or other applications if need be.
