In my testing (https://turbovnc.org/Documentation/Compatibility), GNOME 3 works with -3dwm, so I'm not sure why it isn't working for you, but also, GNOME 3 is not an ideal window manager to use in a VNC environment. It's a compositing window manager, so even if you get it working, it will be slow, and there are a handful of known issues with it in a VNC environment (https://github.com/TurboVNC/turbovnc/issues?utf8=%E2%9C%93&q=label%3A%22GNOME%203%22). Some have workarounds, but not all.
My suggestion would be to install and enable MATE using the instructions here: https://turbovnc.org/Documentation/Compatibility (under "Red Hat Enterprise Linux 7 (and equivalents)"). That will give you a similar window manager to the GNOME 2 window manager that you used with RHEL 6 (MATE is a fork of GNOME 2.) MATE is a 2D window manager, so it will run in TurboVNC without -3dwm. If you absolutely need to use GNOME 3, then try the dev/2.2 evolving pre-release build (https://turbovnc.org/DeveloperInfo/PreReleases), which has a built-in software OpenGL implementation that (again, in my testing) works with GNOME 3 without using -3dwm (although, again, performance will not be stellar.)
