Spot elevation wrong for linked model with invisible volume

[marius.fe]

Hi all, I googled but I did not find a solution for this problem.

I have a family with a maintenance area, see following picture.

I have instances of this family in Project A. I have a master project file B in which A is linked.

In some views of the master project file B I do not want to display the maintenance volume, so I choose custom model categories and deactivate it in the link visibility settings of the Revit Link.

When I insert a spot elevation for the top face, (in the master project file B) it shows 350 although the volume is not visible:

In project A it works as expected:

Any ideas on this?

Edit: I am working with Revit 2022.

What happens if you place the spot on the edge of the visible box? It seems to be pointing to the center. If you put it on the edge, it should show 250 mm. If it doesn´t, then that would be weird.

Dear Alfredo, tanks for the answer! If I select the edge, 250 mm would be shown, correct.

Unfortunately that does not solve the problem.

We need to use spot elevations in a plan views. And in a plan view you do not see which edge/line you are selecting if you have serveral edges/lines stacked.
