@iorileslie, I converted your issue to a discussion.

Please see the documentation and in particular, this tutorial where this is elaborated on: https://docs.gempy.org/tutorials/index.html#chapter-1-gempy-fundamentals

The X, Y, Z coordinates are the location of your input data, formation the rock unit the point belongs to and dip/azimuth are the orientation values needed to calculate the scalar field

OK,thanks. Looks like I need to read the documentation carefully ^v^
