Named views and cameras
Each Rhino named view becomes a Blender camera in the NAMED VIEWS collection, carrying position, orientation and lens.
Cameras are fingerprinted on creation. If you move or re-lens a camera in Blender, Rhino stops updating it. The add-on compares the camera's current state against the fingerprint it stored; once they differ, that camera is yours. This lets you use a Rhino named view as a starting framing and then refine it without losing the refinement on the next sync.
To get a Rhino named view back after overriding it, delete the Blender camera and press Refresh.
