I went through the first 10 tutorials and I want to make sure I'm going in order. Jonathan, is there tutorial “11″? I went through the first 10 tutorials and I want to make sure I’m going in order.

Turns out all the object centers were still sitting squarely on the origin. Probable issue with how I created the gears to begin with. Object >> Transform >> Center to Geometry ended up fixing it. Cheers again :) Thanks for the quick reply, but I managed to guess my way to a solution last night. Turns out all the object centers were still sitting squarely on the origin.

Can you send over your .blend so I can take a look at it?

They all end up being moved around (0,0,0) instead of spinning on the spot. I've tried changing the pivot point but that doesn't seem to help at all. Very new to this, and any help would be appreciated :) I’m sure I’m missing something simple, but I’m having trouble getting the gears to rotate properly.

Great tutorial. I didn't realize something so complex could be so simple. I also like how it is explained comprehensively and gives common pitfalls. Very useful website. :) It is called a Rack and pinion where the rack is the long linear gear and the pinion is the round one (FWIW).

I shall have to give it a try (got me a thing for gears). Question for me would be, what if the gears have different numbers of teeth? I suspect one would have to animate them individually (at least that's how I have done it, calculating the gear ratio). How did you make the gears? I have seen the gear script, but haven't done much with it myself. My normal method is to create the gears in Inkscape, then import the .svg file into Blender and extrude it. Another consideration, depending on what your intended purpose for animated gears is, is that you can get away with animating the gear "by just one tooth" (unless you have specialty gears that aren't symmetrical), saves on render time (I mostly do GIF files, and being able to animate an entire gear in just five frames is a must, it just keeps playing the gear rotating by one tooth over and over again, but the gear looks like it is doing a full rotation). The video below was done with my Inkscape extrusion technique, but not by "one tooth", obviously. http://www.youtube.com/watch?v=acXiebKExQM Very interesting tutorial.

I did the other way around. The location in x direction rotates my cylinder. This way I can do an eternal rotation. Thanks anyway. Ok. I did the other way around.
