Okay...being stubborn isn't working. I've experimented for days trying to learn the steps for creating a simple hydro poly in ADX and all I get are craters. One time I thought I understood it...I had layed out a river over an airport background exclude autogen poly (at least I think that's what it was), and lo and behold I had a river.....except that over the length of it there were 2 or 3 small craters.
Must have something to do with setting altitudes, which is another problem for me, in that when I draw a poly the properties altitude box has a value in feet (which I set as a preference) but if use Set Altitude to FSX, the value changes to something approximating the altitude in meters. Not exactly, just close.
Two questions then...
Is the Set Altitude to FSX value shown in the box, the altitude for the current posiition of the aircraft when in top down slewing mode?
Secondly, what are the basic steps for creating a simple lake? I can take it from there...I think?
