The folks who make a competing terrain product weren't too happy with my back-to-back pages comparing their app's road making procedure with NWDA's... Granted, I created the competing app's renders myself the best I could following their tutorial and Frank provided his own, which I used for the background (I did the smaller ones).
Anyone else tried this spline feature in the other app? I offered to republish their page in my ezine with better results if they could provide them to me but got no reply for 2 months now.
