I have some issues with the explanation of "Axis Rotate":

"We’re using the two objects from the previous example and we want to even them up. Use Axis Rotate and Shift click on the top blue polygon, now the box will be rotated about that polygon’s normal. To get the alignment right, use the Nudge controls in the Numeric Panel to perfect your rotation."

1) The example provide uses a "previous example". While this works in a LINEAR DOCUMENTATION ENVIRONMENT, in the 2018 non-linear online environment it is quite annoying: I can't flip back to the previous page to get oriented.

2) I don't like the casual wording of "even them up" does not clarify-- this could be translation, scale, anything. Phrasing using "ALIGN" would be better.
