Hey @ToanDN, I have a 2022 model where this should be the case, but the linked topography is not adhering to the poche base elevation set in the host model. I am using a view template but I tried creating a fresh cut through the topography without it and had the same result.
The poche elevation base for both models is set to be -200' so I should have plenty of depth. The survey elevation of the building is 86'-0" at project 0'-0". The poche in the host model actually doesn't show up at all until I override the cut graphics at which point I can see that I'm only getting the default of -10'-0". I don't really care about the cut pattern, but I would like the topography to mask the rest of my foundation below grade.
My understanding is that the Elevation of poche base is relative to the project base point, correct me if I'm wrong.
The screenshot from my host model should help clarify.
