It's puzzling.
There's a brief flash of Move 3d at :47 seconds mark when he is creating a new w1, but then the other Pulls generate features that are coincident with the sketched geometry and this one Pull isn't.
Later in the video, 16:30, he is suprised that the gear teeth aren't the same width as the thickness he assigned when he pulled the gear. He gave them the same value of 10, but they are clearly not the same.
This really reminds me why I wanted to use parametric modeling. If the design isn't done before the modeling starts, there's a lot of rework for any minor change. Want to change the number of spokes or the profile of the spokes? Change the location of the main gear so it doesn't interfere with the escapement? Can't just change that 72 degree value to a new one. Instead of changing a value there's a lot of rip out and replace or re-establish references that are immediately discarded when the move is done.
