Using shared location coordinates for multiple houses on a single site

[aysun_ahmed]

Hi 

I am working on a project that consists of 3 houses on a shared site. I have created separate revit files for each house and then for the site. I need to model the terrain now so I am trying to link all 3 models to the site model. My confusion comes when adjusting each file's survey point, project base point and true/project north directions. What is the right sequence of steps doing it so that I can set this whole thing up properly first? I guess I can keep working on the separate building files and the terrain and update accordingly by relinking them to the main site model in the process. 

I have currently set all the survey points to 0, the project base points of each building and their orientations are correct in each individual building file. I now created a site model file with both the survey point and project base pont set to 0 and some levels for the buildings to align with their respective project base points. Here comes my confusion on how to continue without messing up all this while sharing their coordinates.

If someone could share a proper workflow I would be very thankful.

Thanks

Is it hosted on the Cloud? ie: workshared models on BIM360? if yes, see the following Autodesk Knowledge Network article - Acquire Shared Coordinates for workshared models on BIM360 

If it is Workshared/hosted on a local server or you own workstation the process goes as follows

1. Set up site model (Coordinates and Orientation to true North)
2. Link the individual building(s) model
3. Mode/Rotate the link to Position
4. Use Publish Coordinates then pick the building link where the coordinates should be published to
5. Save/Sync to save the shared site
6. Repeat for the other buildings

Alternatively, you can do it the opposite way round by linking the site into the building and using acquire

If you have multiple buildings and a site then I would go with the Acquired Shared coordinates approach, regardless of using BIM360 or not.
