Linked model levels issue

[Anonymous]

Hi all,

I have a building model linked into a site model, i have a level set in each model to mark the basement however when my building model is linked into the site model i get a discrepency in the position of the level. i have attached images below. 

when viewing in the building model, the level that is pulled through for the site aligns as it should... however when viewing from the site model the level oulled from the building model sits 150mm below where it should.

I have the same shsared coordinate system between the 2 models.

Are you using Shared Coordinates? If not, do so

Are the levels in each file set to use the Survey point or Project Base point?

Yup, using shared coordinates,

Project base point and survey point are the same also

How exactly did you setup the shared coordinates between the models?
