As the Space Park effort showed, I’m reasonably good at modeling in CAD. However the CAD program I use has some serious limitations as far as the sort of shapes it can model as solid objects…. anything with organic contours is pretty much right out. But Rhino 3D is advertised as being the solution to that. So some while back I bought a copy and promptly ignored it. However, I’ve fired it up, and here’s the first project: an early 1970’s North American Rockwell stealthy ground attack plane. This is just a first stab at a model and is pretty wrong in some ways; much left to do. Still, at the very least it didn’t explode, so that’s something.

How’s the CG supposed to work on that thing?
The majority of the mass is _way_ ahead of the center of lift of the wings, and the forward body doesn’t even have any sort of chines to give it lift.
You might be able to keep it aloft at high speed by deflection of the control surfaces on the wings, but during takeoff and landing it’s probably going to be fatally nose-heavy.
Barring extensible canards, or some sort of heavy mass at the trailing edges of the outer wings, it’s not even going be able to rotate to get off the runway.
The forward fuselage is quite different from what’s actually shown here. I was just happy to get the wings more or less kinda sorta right. The fuselage contours are, apart from the side view, pretty much entirely wrong.
One step at a time…
