I built up a car starting off with a flat plane then extruding edges and tweaking.. now I only have the side done and need to finish the top but I need to draw a curve for the windshield.... can you draw a curve on a polygon surface? I have googled the crap out of this and posted in here under nurbs and curves and had many views but no replies. So figured I'd try in here. The tutorial I was following did not mention the type of surface.. he just said make one and extrude edges..etc. So thats what I did and now im stuck. Can SOMEONE help? I've even asked this in CGtalk with no luck.
