Ok. The 3d editor is something new that I introduced earlier this year. The next release which should be out in a few weeks is adding a few new features to the 3d editor. The biggest new feature is terrain sculpting. The 2d editor is also getting support for isometric tiles in the next release as well.
In the help menu in the IDE there is a link to the manual that comes with the download. The online manual can be found here: RCBasic 4 Manual
I also made a video going over getting started with the 3D editor here: Serenity3D Tutorial
Also, I am not sure why you were not able to access the discord but here is an invite link: https://discord.gg/Egf5hwEP
