Step 1: Reset the coordinates of the model.

Step 2: Link in by current coordinates.

Step 3: Acquire coordinates from the updated property boundary resource file.

Step 4: Update the Shared Site of each link copy.

The existing shared-coordinate relationship must first be cleared because the authoritative civil background now contains revised GIS positioning. Resetting the model coordinates removes the obsolete relationship and prepares the architectural model to establish a new shared-coordinate system without physically moving its authored building geometry.

The updated property-boundary or civil resource is then linked using its current positioning so that it can serve as the authoritative coordinate source. Once the updated reference is correctly positioned, the architectural model acquires coordinates from that file. Acquiring coordinates transfers the civil model’s survey-coordinate definition into the host while preserving the architectural model’s internal origin and local modelling arrangement.

The final step is to update the Shared Site assigned to each duplicated building-link instance. This is necessary because multiple copies of the same building model may occupy different campus locations or orientations. Each link instance must reference the appropriate named site position so that the copies remain correctly placed after the revised GIS coordinate system is adopted.

Changing link sites before updating the host coordinate framework would apply positions against outdated coordinate data and could displace the campus federation.
