I've never modeled a plane before, but I have some 3D CAD experience and would like to try my hand at a plane of my own. To start with, I'd like to open a default plane to look at and play around with (and learn my way around AutoCAD LT 2004, the only 3D-ish modeling program I have at the moment, too).
According to Hughes-MDflyer4's "Important Topic" on MDL conversion though, other files cannot be converted to or from MDL files. And according to Microsoft, the only programs that can open MDLs are GMax and MATLAB... does this mean I need to buy one of these programs to model a plane for FSX/2004? If so, count me out; I'd rather buy a car with that kind of money!
