What we want to do at this point is negate the effects of shows and light play. We want to confirm facts that we know to be true against what we assume to be facts. In the photos below you can see that I took a previous photo and dissected it across the centerline, I've also shown what appears to be an accurate profile of the engineering hull less the cutouts on the bottom, port and starboard side to come up with a concentric shape of the engineering hul before the details were added. Lets take a look at some of the details as well. In the rotocoped shot of the enterprise it appears that the forward edge of the hull, behind the deflectors rings seems to be rounded, it would also appear that the Polar Lights 1:1000 model got this wrong as well, because when we go back and look at the actual ship, haning in the Smithsonian, back before the 92 "resoration" we see that the shape is an angle and not a radius. Further, in the photo that a rotoscoped the detail on the port side seems to be at an angle when in fact we see from the same Smithsonian photo that it does indeed have a chamfer.
