What is the difference between Autodesk Inventor Pro 2008 and 3ds Max 2008? Also, what is combustion 2008 for? Do I even need 3ds Max and Combustion if I have Autodesk Inventor Pro? If I do, what do I use each software for? I'm a newbie at all this stuff and this is our first year for our robotics team. I'm a freshmen in high school and have only been working with inventor for about a week, having all the basics like constraints, dimensions, extruding, holes, and sketches. No one in my school, including our coach, knows how to use any of these softwares, so I've been teaching myself. Any help is appreciated. Thanks in advance.
