I haven't seen a possibility to rotate the cursor. When I choose cursor as a tool, I can't perform "R" on it. What is the way to rotate the cursor? It certainly can't only just depend on the angle the screen is rotated and where you then press right click on the viewport
Thank you all!
Yeah I don't see a reason to use it myself xd Just still was curious to know how
It can be useful when trying to align objects through snapping to cursor or adding new primitives. Another way to change the rotation is to use the 3D cursor tool and change it's orientation to geometry instead of the default view. Then you can click on any surface and the 3D cursor will align to the angle of the surface under it.
