If you do not have the same "feeling" as Chip Hyde, you should then consider using some good 3D programs out there. I am familiar with Solid Edge and can say it is capable sofware. We use it for drawing a 4 seater homebuilt plane. Every part is made with rivet holes already pre-punched and everything lines-up really good.

We sure would not have been able to draw this plane on paint...
