CPlane changes every time I enter in and out of Perspective

Rhino

C plane constantly changes. I keep having to return it back to World Top. Does anyone know how to lock the 3 plane to avoid issues like this:

My guess is you have an unfamiliar combination of Universal/Standard Cplanes; (linked instead of each viewport independent), and perhaps OneView turned on.

Do you have AutoAlignCPlane enabled?

Hi John,

Could you recommend a setting type that you think could solve this issue?

I am still having this issue. It first started after rebinding some keyboard shortcuts to move me in and out of Left, Right, Front, Back, and Perspective view.

I do not know what is going on. Very strange.

I guess if it were me, I’d reset the Rhino PLIST:

Any luck?

Hello,

I am not sure how to determine whether or not this is enabled.

That’s a Rhino 8 WIP command. If you enter it, you’ll get a little menu in the left sidebar that shows, whether the option is enabled or not.

In this case it would be, since the box is checked.

Hey John. This did not solve the issue. I ended up downloading AppCleaner to complete wipe all rhino install files, cache, and libraries. Then I redownloaded. Problem resolved.

Thank you for your input.

Thank you for this.

I’m not familiar with that tool.
Thanks for reporting back.

You are welcome. It is a bit of a work around as I never learned the root cause of the issue. Oh well.

I am having this issue also in R7 Win. When returning to Perspective it retains the previous views CPlane. I’m using keyboard shortcuts to switch views, Ctrl+ function keys.

Adding _CPlane _World _Top to the end of the keyboard shortcut macro doesn’t consistently return the cplane to world top. Running it a second time does though. (Aside - Even using the button doesn’t always return the cplane to world top in perspective view, a second click usually fixes it.)

Hi Nick -
Please provide the macros that are involved here.

Ctrl+F12 - Perspective '_SetDisplayMode M S _CPlane _World _Top
Ctrl+F11 - Top '_SetDisplayMode M W
Ctrl+F10 - Front '_SetDisplayMode M W
Ctrl+F9 - Right '_SetDisplayMode M W

Universal Construction Plane is in use. Perhaps this is the reason for the odd behaviour.
