Manage the position of the building model relative to other buildings.
A Revit project has internal coordinates for all the elements that compose the model in a project. Those coordinates are known to this project only. This is acceptable if you have a standalone model whose position is not relevant to other models or to a site. However, if you want the position of the model to be known to other linked models, you need to share coordinates.
Shared coordinates are used for remembering the mutual positions of multiple interlinked files. Those interlinked files can be all Revit files, or a combination of Revit, DWG, and DXF files.
If the significant coordinates for a project are in a linked model, such as a building model with a linked site, acquire the coordinates from the linked model.
If the significant coordinates for a project are in the host model, such as a site with linked building models, publish coordinates from the host to the linked models.
