3D Grapher 1.2
3D Grapher is a great program for people who don't have hundreds of dollars to spend on a professional program.
Just because this program is small, however, doesn't mean that it lacks quality.
3D Grapher comes equipped with all necessary tools for designing and manipulating professional graphs and models. With OpenGL graphics support for animation, you can have your designs up and running in no time. While this isn't as powerful as some high-end CAD programs, it is much more valuable than its price tag indicates.
