Application Notes

*The GX.NET tools are embedded in the geogxnet.dll file located in the \Geosoft\Desktop Applications\bin folder. To run this GX interactively (outside the menu), first navigate to the bin directory and provide the GX.NET tool in the specified format. See the Run GX topic for more guidance.

In GOCAD, the standard is Z-positive down (depth), whereas in Oasis montaj, the convention is Z-positive up (elevation). In the dialog, you may specify either a 'standard' or an 'inverted' orientation, where 'standard' follows the Geosoft’s convention, and 'inverted' follows GOCAD's standard, as shown in the table below:
