One View and Custom CPlanes - SUGGESTION


I often work in the OneView CPlane mode to allow me to work in a single perspective viewport. This is great. I also often use Custom CPlanes which I save in the Named CPlanes panel. This is also great.

But, I don’t think they work very well together, unless I’m missing something. If for example, I’m working in OneView and I want to momentarily activate a Custom plane from my list to work on, as soon as i rotate the viewport, OneView over-rides it and toggles through the other planes (as expected). In this scenario, doesn’t it make more sense that the act of selecting the CPlane from the Named CPlanes lists, over-rides the OneView? I almost want an over-ride checkbox, or some function that works together with the Named Cplane panel.

Auto CPlane does this somewhat (which is a great addition by the way!) with its ‘Lock’ and ‘Sticky’ options…

In conclusion, I think that there needs to be better syncing between the two functions, which are good in their own right…

Would be good to get others thoughts on this type of workflow/process.

Any thoughts on this?

Hi Sach -

That’s just a matter of changing the settings for that command, no?

In that example, “CP-Roof” is my custom CPlane and that doesn’t get overridden as soon as the viewport is rotated. This is with the Angle option set to 45.

FWIW, I have had OneView in my start-up commands from before that was turned into a command but when AutoCPlane came around, I stopped using OneView. I set the AutoCPlane Lock function to my Tab key and lock custom CPlanes on the fly all the time without having to worry about creating those.

Thanks @wim

Yes, I often set it to a large angle. I find that this becomes ineffective if you have planes that are closer to parallel with each other… Then Rhino struggles to toggle effectively between the custom planes.

Yes, I have been utilising this great tool and it works great with planar surfaces. As soon as I work with the curved surfaces, this doesn’t function so well. In these cases, Oneview and custom Cplanes, I think are still relevant.

In summary, I think a simple ‘lock’ check box next to the custom Cplanes in the panel could help this to better work with OneView.

Good to know your thoughts.


Hi, I am using 3DConnexion Spacemouse and the OneView mode doesn’t work with this mouse. Oneview mode only works with right mouse click. Could I ask McNeel for improve Rhino or ask 3DConnexion?
