Hi
If not easy say you yes or not...depent of what aircraft is it. It is a scale? Do you have some picture of the real thing? I design model aircraft, you can see my site
www.artecnc.com.ar . I work with Autocad and Rhino. And I did some plugs to then make a fiber glass fuse, Scandalous an Brio fuses, and cowls to CA Model Extras, and many others. If you send me the files maybe I can help you.
