They way I do it is draft it in 3-d using autocad, depending on the part, you can draw it in 2-d. That's really the only way, so you must learn how to draw using a cad program.
I am new to this stuff, and still havn't got my cnc machine together yet, I want to make some parts for my micro heli, mostly just replacement parts of the stock one, if or when they break, whats the best way to duplicate them, I downloaded a cad program but getting nowhere, I am no good at it, and cant even figure out how to use it.
If any of the schools near you have a metal shop with foundry technology. You can take them the parts and they can cast them for next to no cost. Usually the shop teachers welcome real world issues for a true exposue to the students.
Afterwards they usually like you to come back and show the students what the parts they made actually do. This helps the community and you, not a bad deal.

here are some pics ( 3D solids) that I made using Solide Edge... and I made the parts in aluminum in an DAHLIH MCV-510 with Fanuc series 0-M control.... but i made the program using EdgeCam...
(the size of the parts are about what you see on the screen)
hope you like it...
