This is what I've been busting my butt designing this week.--Nahh---It isn't a hovercraft!!! I just haven't got to the wheels yet. Better this week than last week. Last week it was curved windshield assembly fixtures, which involved far too many compound angles.---It gets really nutso when you design something that is so complex that there is no way to draw it---the math data goes directly to the CNC Gods for fabrication. At least on something like this the angles are generally in only one plane.
