To Export Clash Results to a GPS

Define a Geographic Coordinate System.
In the Clash Detection dialog Results tab, select the clashes or clash group(s) you want to export.
From the Results menu, select Export > GPS.
The Export GPS File dialog opens.
Set the output location, give the .GPX (GPS Exchange Format) file a name and click Save.
Import the GPX file into a GPS device.
You can then take the GPS device on-site to show you the location of the clashes.
