Nested structural family

Im having an issue with my nested family (image) when loaded into projectthe endplates dont show up and causes the entire family to be deleted with the error message as below in in´n the second image.

Any solutions?

don't know what "Andplat_2" means :-), but its the visibility parameter assigned to the plate and it is Off by default. if you check the check box the plate turns on. I did not get any error when placing or manipulating the family in my model.

Hmm strange I've tried that as well but my family still seems to be off.. Anyways at least I know its working. Thanks 🙂 Guess it's my project that's spooking around.

I found my issue.. Apparently Revit isnt to keen on switching an already set out family with an nested family due  to all the new constraints that the Nested family comes with.. But ''redrawing'' the beam works without any issues 🙂
