Best Practices for DXF Export in Uinta

19 Jun 2025

Geospatial data uses one of the following primary coordinate systems:

• A Projected Coordinate System (PCS) defines how to display the data on a flat surface (such as a computer screen) using linear units.
• A Geographic Coordinate System (GCS) defines the data's location on the earth using latitude and longitude.

When exporting Uinta geospatial data for use in CAD software, you must use a PCS (such as a state plane or UTM system). Uinta embeds the PCS metadata in the exported DXF file. This allows the CAD software to detect and apply the correct coordinate settings.

You can select the PCS when you customize the file export or within Location Settings. If you export a DXF file without selecting a PCS, Uinta prompts you to switch to one. It then automatically selects a suitable UTM zone based on your data.
 

Instructions for Civil 3D 2025 (or Later)

Civil 3D 2025 (or later) may not recognize the PCS embedded in Uinta's DXF metadata. When this occurs, the Geolocation tab does not appear in the Civil 3D ribbon.

To resolve this issue, 

1. Open Civil 3D.
2. Open the Settings panel on the left side of the screen.
3. Right-click the drawing name, and select Edit drawing settings.
4. In Available coordinate systems, note the selected coordinate system.
5. Select a different coordinate system from the list and click Apply.
6. In Available coordinate systems, select the original coordinate system and click Apply.
7. Close the menu. The Geolocation tab should visible in the ribbon.
