That's interesting that the OOTB method works. You are aware that 2025 now has the SDB capabilities in ACC, I would assume. Perhaps that has something to do with the this.
We don't trust Autodesk to actually get something right, especially something this new when they can't even get the SSM to work properly on ACC. We are finished with the survey portion of this project and we started it back in March before Autodesk supposedly added support for the SDB. One thing to note is that any point style marker that's using the built-in cross, and not a block, does show up. It's only styles that use a block that do not show up when XREF'd. And it's not just my workstation. This happens to another user that's using C3D 2024, so it's not just my workstation nor C3D 2025.
Did another test. Created a new drawing using the same project template. XREF'd the survey drawing and the symbols show up. Have not saved this drawing anywhere.

I then saved the drawing, closed it, reopened it in the same C3D session and the symbol is showing up correctly in the test drawing.

In my utility crossing drawing where I'm modeling the crossing utilities I have XREF'd this same survey drawing. It has our flattened, 2d existing base drawing XREF'd, but it has items not from the survey in it or changed, so I wanted to see what's different between the two. When I XREF this same survey drawing into this utility drawing (created using the same project template as the test) the symbols do not show up. I've highlighted the survey XREF below. Notice that where the valve is supposed to be nothing is selected/showing?

I just added this XREF, so there's no altered layers or anything. This is a fresh XREF that I just created for this reply.
