Aligning objects with the user coordinate system (UCS) and the Rotate command

- Now that we've modeled the pedal,…it's time to place it in the crank.…Let's turn off this layer which is layer pedals…and we will delete these guidelines…that were created earlier.…This is composed of various elements.…To keep everything unified,…let's group these objects together.…Type group, enter, and select all of those components.…Enter.…Now it's treated as a single object.…I need to rotate it along an axis running this way…in order to get it in that hole in the crank.…

So, to do that, I need to rotate the UCS…so that the Z axis is parallel to that green line.…Type USC, enter, Y, enter, enter.…Now the blue axis is going in the right direction.…So, I can now rotate this object from the center…and I'm going to rotate it around like that.…I can then delete this line…and I can move this into position.…I'll say move this object from the center…to this lower center snap point.…

To see what's happening, I'm going to select the pedal…and then orbit underneath.…You can see that it's in the right place,…however, this shaft is too large.…
