Rotating a rectangle

Hi Guys, I’m learning a grashopper, i have this rectangle that i want to flip(just like the one in rhino) in order to create a steel beams. However, i found two problems:
1)it always moves it around the cplane/axis not its own axis and thats annoying. Can anyone give an advice?


Plug in a different plane to create it on the same plane as your rhino rectangle. Else use construct plane if you want to use your point as the origin and change the plane.
