How do I rotate the visual part of a cplane?
The construction planes will align or orient with the default planes. There's no option to rotate the plane; however, there is a way to re-size the plane and make it larger.
Check out this Screencast for details.
Otherwise, you may be able to create a sketch profile to create a similar reference.
I hope that helps. Let me know if you have any questions.
