This is basically just copy/pasted from Yahoo answers, asking here just in case anyone might happen to know of something..
I'm trying to find a simple and easy to use 3D modeling program that will allow me to design a homebuilt R/C car, the only things that will not be custom made by me are the wheels, servos, engine, transmitter and receiver. So that means I need to design everything else, from the frame (I plan on making a tubular chassis for the base, most likely with steel plates to mount everything on) to the steering arms, the body, and even the suspension system.
I don't foresee a need for it past this project, so I'd rather not spend a lot of time learning to use a program.. However since this will be fairly intricate, I need to be able to create a 3D diagram to figure out how it's all going to go together. I need it to have the ability to create curved tubing above all else, since that is what everything will be built around.
I've been Googling for the last couple of hours and have yet to find something to fit my needs.. Either the program is far more complicated than I feel like messing with (where it would take me days at the very least to actually get the hang of it and have everything moving somewhat smoothly) or it's too simple to suit my needs..
I have extensive experience using Photoshop, Adobe Premier Pro and Sony Vegas, so these programs aren't out of my scope of do-ability (I could even learn to use the most complicated of the programs, I'd just rather not).
