Creating or changing CPlanes often disrupts the modeling workflow. Rhino now has Auto CPlanes, which auto-align to a selected curve, surface, mesh face, or subobject. Automatic CPlanes make it easier to work in a single 3D viewport, making it simple to draw on the face of an object.
Universal CPlane
Rhino allows you to work with a universal CPlane. This means that the orthogonal viewports will become relative to the CPlane set in a 3D perspective view. When combined with Auto CPlane and World alignment, this means the top view will always be aligned with the face that gets selected. This allows you to quickly look at, and work on, the selected face in plan view.
