This can be performed by first exporting the TSURF (ASCII) file, from a built 3D geology model:
- In GeoModeller, from the Main Menu: Export > 3D Model > Shapes
- Choose Type: TSurf
- Select: Create Archive File
2. Next, using a text editor to retrieve the TFACE VRTX: X,Y coordinates (Triangulated Face Vertex Nodes)
An example Tsurf file (ASCII) – exported from GeoModeller, showing which values need to be extracted to retrieve the x,y,z points data from the built 3D surfaces
