How to trim frames to a 3-way mitre?

Hi all,
I joined a TIG welding course and we needed to pick a small project to start with.
So I went for a small cube of aluminium profiling, but I was wondering how you would typically model a 3-way mitre using the Frame feature in Onshape?
I'm familiar with it, but I assume that I need to model that 3-way mitre manually?
Here's a video tutorail from Solidworks: https://www.youtube.com/watch?v=g3finW8cv3I
Any suggestions?

I don't believe there's a way to do a 3-way miter automatically. It's easy to do a 2-way miter with a simple frame feature.
With a cube, I would most likely manually create a surface or solid to cut an end, and then reuse that for the second end of a frame member, and then reuse the same frame member 12 times in an assembly.
If I was doing 3-way miters all the time, I might get someone to help make a custom feature to create that type of trim. I would also suggest creating an improvement request to have that be a first party function.
You can do ordered trims, but they don't seem to create miters.

Here's a document which uses some surfaces and a split feature to create the 3-way miter on the ends of a single frame member, and then the assembly uses some patterning and mirroring to get all 12 parts in place.
