    Thanks! I just tried this and it's not working haha, but I suspect it's like the workaround with the corners of the eccentric footings to drag them: sometimes it works and sometimes it doesn't.

    Thankfully, while architects may want all their concrete joins to be clean, this is how we should handle structures. Beams and columns are almost never poured together. We just need to make sure they are modeled properly.

    If anyone knows why Revit is installing old libraries in the new version folder, I would appreciate it.

    I think you better create a new topic on this issue.

    I figured out the issue I was having. Setting the structural material to a type parameter breaks the concrete joining functionality of Revit. It must be an instance parameter.

    Ok, I upon further testing and research, this is not the actual solution that fixed my issue.

    Instead, I leanred that the concrete column extrusion in the family must be set to be visible in fine, medium, AND coarse detail. Otherwise the concrete join behavior does not work.

    Second of all, the automatic join order seems to be broken, at least in R17. This post accurately describes what needs to be done to get a proper clean join:
