Missing F6

I have a question.
F6 is missing, How can i get it back?
also use Middle mouse button, F6 just don’t show up.

This is the default behavior, but you can change it to do whatever you like:

Hello - the default macro for F6

! _Camera _Toggle

You can set that in Options > Keyboard page.

-Pascal

If you’re talking about the F6 adaptive menu from Matrix, then there isn’t really the same thing in native Rhino. You can modify the popup toolbar that appears when you click the middle mouse button and put whatever tools you need in that toolbar.

The contents of the toolbar won’t change when you select different objects, but you can still make it very useful.
