What program do you guys use to make the good looking drawings such as the ones in the theories section? If you can, tell me where I can get it for free aka downloadable.

macromedia fireworks is awesome for this stuff, just overall better controll than photoshop, short loading time, more and better features, and saves to a web friendly png file with all layers still in

i also love using rhino 3d for stuff

i gues with rino 3d you cant make a propane bottle ore a ball valve?? so yes plz tell me how to, becaus i don't get it.

You can, just there isnt a auto "ball valve" shape. You can construct your ball valve by using a combination of the following: all the basic geometric shapes, "extruding" 2D objects, "revolving" 2D objects, and using shapes to "minus" from other objects. There is infinite ways to in which "model" a ball valve, although some may be more effeinent then others. It takes some creativity...

i can make something like this no problem
