Making New Settlements Help FO4 (Creation Kit)

[Chthonian]

So I want to create some new settlements for Fallout 4 using the new Creation Kit. So of course I loaded up the CK to take a look at all the things that are involved in a settlement. I am using the Starlight Drive settlement as a reference while trying to make my own. Looking at Starlight Drive's Workbench, I've basically just been setting up my workbench the same way, linking certain references to it using keywords. The thing I'm stumped on however is the part that says I need to link up a Workshop Sandbox Area REF to the workbench. I found a post on bethesda.net talking about this very thing and the answer appears to be to use a bounding box, resize the box to the size you want around the settlement and link the box to the workbench using the keyword "WorkshopLinkSandbox". What exactly are they referring to when they say bounding box? I've tried all the things I thought were "bounding boxes" but nothing is working and does not show up as the same thing that the workbench says its linked to in the Starlight Drive settlement. I have even tried copy render on the box at the Starlight Drive settlement and pasting it at my location and renaming it to see if that would work but it didn't. The Reference editor ID at the Starlight Drive Settlement is: "StarlightDriveInWorkshopSandboxArea" and the Base Object is: "Default Dummy". I'm pretty sure that "Default Dummy" is just the basic default model the game uses to show anything that isn't "defined". So what I need to know is how do I go about making a "bounding box" for my settlement to define the building area. I know this is probably something very simple but it has me stumped and rather frustrated at the moment and I just need some help figuring it out as I want to begin making new settlements for the game, I just need to learn the ins and outs of making them work correctly. So if you think you can help me out at all, if that is even just giving me some advice on the subject, I'd much appreciate it

 

I also took a couple screenshots of what the reference windows look like for the workbench if that helps at all

I know how to do it in fo4edit. Create a REFR in your cell call it something like sandbox area

Base- Defaultemptytrigger

Then un XPRM - primitive

put in x,y,z bounds

Then make the type a box
