I am currently working on topographical projects and I want to create 3D model with ground surface with a picture attached to it and KML files. For KML is it possible to export 3D kml with the walls? To do this I use this line in my thconfig export model -enable [walls] -o output\adavoustekml.kml but the kml contains only the centerline. With the line export map -o output\plan.kml I have a nice kml file but it is a 2D kml. For the Surface in loch I use a file colline.th which I include in my project file This colline.th begins with those lines : surface cs UTM31 bitmap /data/adaouste_redim.png [0 0 714040 4839736 1276 1375 714495 4840755] grid-units meter grid 714600 4839900 010.00 10.00 10 15 416 417 419 423 423 425 424 422 420 418 ….. endsurface. In my thconfig file those lines have been added to export the model : export model -o output\adavouste3D.lox The final loch contains the 3D model of the cave and the ground modeled by the surface but it is not textured by the picture. I should make a mistake but I do not know which one. Thank You for your helps. Matthieu EGELS Maître de Conférence. Université d'Aix-Marseille Enseignement: IUT d'Aix-Marseille, Dep.
