And the STL graphic file.
Incidently I have also tried making a contour map with SketchUp following this tutorial but I can't get much joy with that either.
Thanks again for any...
Thanks for your replies. I's so infuriatingly close!
Solidworks will import the map as a drawing fairly well (only the 3rd layer is needed) for the contours. But then the height information is lost and the sketch doesn't behave very well. Annoyingly importing the 3rd layer as a 3d part only...
Has anyone ever tried and had any success in opening any of the Ordanance Survey's Landform Panorama map data into solidworks?
The download is huge so I have attached an example map from the file.
Ideally I would like a part in Solidworks representing the topographic map data in the file...
