Coordinate Reference Systems in Add Location

Use a Coordinate Reference System (CRS) in SketchUp's Add Location to geolocate your model. A CRS represents real-world locations using Easting and Northing coordinates for precise positioning.

CRS in Add Location

Before you use a CRS in Add Location, check these requirements and limits:

• Check your project's EPSG code to identify its coordinate system, or have a CRS calibration file ready.
• Your CRS determines the coordinate units your project uses.
• You can't adjust True North when you use a CRS.
• After you geolocate your model with a CRS, you can't change its CRS or switch to another geolocation method. To use a different CRS, clear the model's geolocation data, then add the new CRS in Add Location.
• To use CRS, you need a SketchUp Pro subscription, one of the Pro subscription options, or a Studio subscription.

To geolocate your model with a CRS:

1. In Add Location, choose Coordinate Reference System (CRS) from the dropdown under Method.

2. Select the CRS your project uses. If needed, search by EPSG code or name. Add Location uses the selected CRS's units for your project coordinates.

3. Enter the Easting and Northing coordinates for your Project Base Point. The Project Base Point links your model to its location within the CRS.
4. (Optional) Switch the elevation toggle off to change the elevation manually. Add Location automatically retrieves the elevation associated with your CRS.

5. Click Update to geolocate your model with the selected CRS.
6. Review the information to confirm that the CRS and Project Base Point are correct.

CRS interoperability

These limits apply when you import or export CRS content:

• SketchUp doesn't recognise or use CRS information in imported files. Check the imported content's position before you use it in your project.
• The .skp format keeps your model's CRS information as IFC data.
• Exports in any other format don't keep CRS metadata.
• Results may vary with third-party extensions. Always check the position of geolocated content when you use an extension that uses SketchUp's geolocation data.
