Overview of Revit coordinate systems
Understanding the Revit coordinate system will help us set up the Revit project correctly and avoid any rework in the future. Therefore, it should make us more efficient.
There are two coordinate systems in Revit, as follows:
- The Survey Coordinate System:
The survey coordinate system uses a Revit object, called a Survey Point, to locate the project on the Earth's surface with a real-world coordinates system. We can acquire this information from a survey file or Ordnance Survey Maps (OS Maps):
- The Project Coordinate System:
The project coordinate system uses a Revit object, called a Project Base Point, to locate a specific coordinate point near your building or site:

Let's find the survey point and the project base point in Revit:
