Hi.
As others have mentioned to get a 3D model you have to use some special tools and the simplest that I know of, least amount of time spent in learning it, is Sketchup to get the 3D portion and Export it to XPlane. I've done some models in XP10 but unfortunately XP11 is more complicated and due to the disorganized process existing presently, where their own C172 may not work from one version to the next, and the fact that the "blade theory" they use is somewhat useless when it comes to light GA models, like the C172, I will no longer consider it as a tool, or even a decent game.
The commercial Developers are having a very difficult time keeping their models working from version to version and free developers, for acft development, are virtually none existent.
Their flight dynamics for light GA, during taxi in Xwind conditions and in flight is lacking and I do not think the blade theory they use now, as it is presently, will ever be able to accommodate / create a decent light GA model.
I use FSX and or P3D, or Flight Gear, as tools to demo maneuvers and recommend it to other pilots.
VR is not very good and after a few hours you are likely to go back to regular use, lack of controls access, and resolution display quality is lower and you are better off using it in 4K without VR.
There are some some flight simulator games like FS2, that I understand is fun, and a couple of others.
It will be interesting to see what future brings for LR / XPlane.
