Filleting edges and arraying sprocket components

- Let's build the sprocket right here, this object.…It carries the belt.…You can see that it has teeth that interface with the belt…where the belt has these minima in its curves.…Let's go ahead and copy this plan drawing over to the side.…500 milimeters, so that it matches up…with the cross-section diagrams over here.…To minimize the complexity of what…we see onscreen, let's isolate the layer.…Use Lay-Iso, and click on the sprocket.…

Now we have a plan drawing and an elevation drawing.…And we also have some profiles over here,…which is going to make creating this much easier.…Let's move these profiles over…and attach them to the center of the sprocket.…Now we need to rotate them.…The rotate command rotates objects around the z axis.…I'm going to rotate the coordinate system with that in mind.…I'll type UCS, y, enter, enter.…Now the z axis, shown in blue,…is in the correct orientation.…

Use rotate, and rotate the previous selection set.…So type P at the "select objects"…prompt, to select those three items.…Press enter.…
