Regarding the geologic contacts on the surface

Hi everyone,

I want to ask if there is a faster way of generating a shape file of the surficial geologic contacts besides manually drawing polylines along the said contacts. The contacts are the edges of the meshes of respective lithologies. Thank you!

    Hi Raymond

    To create your contacts proceed as follows:

    The first step is to create a horizontal plane using the command Create a Mesh by Moving Plane at the Meshes Folder. This plane has to be on a reasonable elevation that's permits cuts the litologies.

    Now you could generate this lines (contacts) by an intersection of the mesh lithologies with this horizontal plane, using the command:  New GIS Line> From Intersecting Mesh, in the GIS, Data, Maps and Photo folder in Leapfrog.

    After create these GIS lines, (that represent your contacts), you could project them on topography.
