Yes, the window wall was actually curved in a segmented fashion and angled outward to match that of the saucer rim's edge. Great care seems to have been taken to match the curvature of the saucer rim, even though there are no windows of this type in this location of the Enterprise filming model. Here is an image of my set (built to the schematics) with my 1000' Connie Refit model's saucer over it. You'll see it's a match.

But, as stated before the set is taller than the 10 foot deck height, so it has to be positioned below the centerline of the saucer's edge.
It's supposed to be at the very front tip of the saucer given the movement of the stars and the way the set was built, but there are no windows on the exterior model to match. I believe I read at one point that they were going to add the windows to the model but ultimately did not.
