And just to be clear, if you use the path command, it will list the graph3d directory as one of the directories on your path? For example, on my machine, I would see this as part of my search path:
.../MATLAB_R2016a.app/toolbox/matlab/graph3d/
If that is true, then the first thing I'd do is check your drive, using whatever disk checking utility you have available. Verify that it has not become corrupted. I'd verify the disk permissions for that directory to see if they had been changed in some way.

Try typing these in your Command Window:
restoredefaultpath
rehash toolboxcache
If those don’t work to give you access to the built-in functions, contact MathWorks Tech Support.

That works. Another option is to copy those two commands to a .m file with an easy-to-find, descriptive file name, then running the file when the need arises. That’s what I do with some configuration commands I occasionally need to run.
If you can’t run the file for whatever reason, you can just open it in the Editor and copy and paste the commands to your Command Window and run them from there.
