Project Base Point and Survey Point

Use the project base point and the survey point to provide context for the model.

  • The project base point defines the origin (0,0,0) of the project coordinate system. Use the project base point as a reference point for measurements across the site.
  • The survey point identifies a real-world location near the model, such as a corner of the project site or the intersection of 2 property lines. It defines the origin of the survey coordinate system, which provides a real-world context for the model.
Topics in this section
  • About the Project Base Point
    The project base point can be used to establish a reference for measuring distances and positioning objects in relation to the model.
  • About the Survey Point
    The survey point provides a real-world context for the Revit model.
  • Display Coordinate Origin Points
    By default, the project base point and the survey point display only in the site plan view. The Internal Origin is off by default in all views. You can make them visible as needed.
  • Define the Project Base Point
    When you start a Revit model, specify the location of the project base point to establish a reference for measuring distances and positioning objects within the context of the model.
  • Define the Survey Point
    Specify the survey point to provide a real-world context for the Revit model.
  • Move the Project Base Point
    After initially defining coordinates for the project base point, you can move it later if needed.
  • Move the Survey Point
    After initially defining coordinates for the survey point, you can move it later if needed.
  • Best Practices: Project Base Point and Survey Point
    Consider these strategies to optimize your use of the project base point and the survey point.
