The file surface.grd does not exist

[NicoTapia]

Hi all,

I'm a new RockWork15 user, I'm trying to do a Multi-Log Section but I can't because I obtend the following Error Messaje: '' The file C:/ Users.... surface.grd does not exist'' . How can I generate this surface.grd file? Thank you very much.
