I am working on a design for school and I need to produce an animation to present the idea clearly to my professors and possible manufacturers. I do most of my design in SolidWorks, but I realize that its limited animation capabilities will not be adequate; so I found Blender. It seems like a really fantastic program that I would like to learn more about. Without explaining exactly what I am doing I essentially need to animate an inflating tube that is unrolling. Imagine one of those party favors that you blow into causing them to unroll and straighten out. I have played around a little bit with blender, learning the interface and basic static modeling. I don't have the faintest idea how to start this though so I was hoping you guys might have some ideas and places to begin.
