GPS .gpx file import questions.... in Q&A Posted April 27, 2017 On 4/24/2017 at 5:34 AM, KirkClemons said: Hello P15-D24, Yes, you are correct in assuming that you need a plan file to import the terrain into. But you only need an existing terrain perimeter to see the data, if you don't have any track points. If you have Track points, in your file, then you want to import those as 'Terrain Perimeter'. These would normally outline a path, so be sure they outline the perimeter of your lot. Waypoints should be imported as 'Elevation Data'. These define the actual elevation of a specific point. Once these are imported into the plan, move your terrain perimeter to encompass them,(if you didn't use any track points) and your 3D view should update with the new information. Got the import working finally and now trying to figure out the best methodology to build the model. I imported a track around the property lines as the terrain perimeter plan. But as a terrain perimeter is doesn't have any elevation data. I tried re-importing the perimeter track as elevation data overlaying it on the terrain perimeter. It appears to work when viewed in 3D (need check some of the data points) but is that the best way to start? Second how do I add in the elevation data inside the terrain perimeter? Do I have to do multiple waypoints and import them as elevation data? Does it automatically position in the existing terrain perimeter or do I have to manually try to locate it correctly? (I would have a lot of waypoints to import due to the terrain variations ;-( ) Can I run another, non closed loop track to pick up the elevation data and just import it? (Again will it be positioned correctly in the plan?) Lastly, how can I set the "bottom " of my elevations, my yard ranges from 140' to 110' above sea level. When I view in 3D I have a really thick 3d image, so I want it to just calculate the 140'-110' range, less 100' (Range would be 10' to 40' in the 3D model) Thanks for any help you can provide.
