How to rotate an object

I downloaded an object from the 3D Warehouse, and now am trying to rotate it 180º. I may have solved the problem from my post a few minutes ago, but don’t know yet because I’m encountering another problem:

I select the Rotate tool, click on the point on the object I want to rotate around, start rotating, and type “180”. This used to work for me, but it isn’t now. When I type, nothing appears in the box at the bottom left, and the object doesn’t rotate.

Any tips?

You need to click the center of rotation > click a second time to start the base line where to rotate from to start rotating > only now you can either click a third time to finish the rotation or override this input by a new angle value / or directly type the angle value.

Ah, it’s coming back to me now - thanks.
