Making a chain drive for gears

- In this third and final gear demo,…we create a chain drive.…We're going to solve this in a couple simple steps.…First, we have a curve used for a path.…Then we use some link parts, already made,…and array them along this curve.…Let's review the scene here in Perspective.…We've got a couple existing gears we did previously,…and we've added one extra.…You might notice that curve path is a little bit deformed…and bent.…This happens a lot when you have complicated geometry…or just a busy scene.…

When things are being drawn,…they sometimes snap to the wrong spot.…But it's very easy to fix, as long as it looks correct…from one of the views.…Here in the front, it looks perfectly fine.…So we're going to use a command called Project…to the construction plane,…and flatten that out so it's perfectly flat and aligned…to the gears and the links.…So that's under Transform,…we Project to CPlane,…which is short for Construction Plane.…Hopefully you knew that.…We're going to select the objects,…which is just the one deformed curve,…
