Casey,
I am sure someone more knowledgeable can answer your questions better then me but I will give you my 2 cents worth.
I very much doubt if AutoCAD would import cuz it is an entirely different animal. In 3D modeling you don’t “draw” the model, you ”construct it” with various shapes. My DBG sides are made from 1x1x1' cubes that have had their dimensions changed to 2.5" x 2 ½' x 31 ½' to represent sides. The vertical metal straps on the sides are likewise made from individual 1x1x1' cubes. The wheels are made from 1x1x1' cylinders sized accordingly. The basic cubes, cylinders, spheres, etc are called primitives and every part is made be altering one of them and then placing it in the proper position. After you make the model you “texture” (paint) it and must use a program like Paint Shop Pro to make the textures.
The “more realistic model” depends more on how much effort you put into making and texturing the model, then which program you use. Realism can be overdone because it makes larger files which make it harder for the Puter to process it. I have removes some detail from my DBG just to make it more computer friendly.
My recommendation would be to get TSM (the simplest program), make a few simple models, and then decide if you want to move on to a more complex program. The biggest problem in 3D modeling is people starting with a complex program an making a ‘realistic”model on their first try. There are tutorials for all the programs on the internet and there are several forums where people will help you out when stuck.
Hope this helps, Bill
