GOCAD to Voxel

Use the Voxel > Conversions > GOCAD to Voxel menu option (geogxnet.dll(Geosoft.GX.VoxUtils.ImportGocadToVox;Run)*), to import GOCAD Voxet files to a Geosoft Voxel.

The import only supports GOCAD files in IEEE float format with property data in an external file.

GOCAD to Voxel dialog options

GOCAD Voxet file	Browse to select the GOCAD Voxet file to import. Script Parameter: IMPORTGOCADTOVOX.GOCAD_VOXET_FILE
Output voxel	Specify the name of the Geosoft Voxel file to generate (.geosoft_voxel). Script Parameter: IMPORTGOCADTOVOX.OUTPUT_FILE
Property to import	Select a property in the GOCAD Voxet file to import. Script Parameter: IMPORTGOCADTOVOX.PROPERTY
Orientation	Select the orientation of the Z axis of the GOCAD file. Script Parameter: IMPORTGOCADTOVOX.ORIENTATION "Standard" is +Z up and "Inverted" is +Z down. See Application Notes for GOCAD and Oasis montaj conventions and standards..

Coordinate System

The Coordinate System dialog allows you to specify the correct coordinate system information (Datum and Projection Method) for the incoming GOCAD Voxet file.

Script Parameters:

IMPORTGOCADTOVOX.IPJ_NAME
IMPORTGOCADTOVOX.IPJ_DATUM
IMPORTGOCADTOVOX.IPJ_METHOD
IMPORTGOCADTOVOX.IPJ_UNITS
IMPORTGOCADTOVOX.IPJ_LOCALDATUM

Application Notes

*The GX.NET tools are embedded in the geogxnet.dll file located in the "...\Geosoft\Desktop Applications \bin" folder. If running this GX interactively, bypassing the menu, first change the folder to point to the "bin" directory, then supply the GX.NET tool in the specified format. See the topic Run GX for more details on running a GX.NET interactively.

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 “standard” or “inverted” orientation, where "standard" is Geosoft’s standard, or “inverted” equates to GOCAD standard, as shown in the table below:

If a 3D Viewer is open during the import, then the output voxel will be displayed in that 3D view. Otherwise, the output voxel will be displayed into a new Voxel Viewer window. If the output voxel does not display, open the Advanced Settings dialog (Settings | Global Settings | Advanced) and under the Voxel Settings section, check if the Display Created Voxels option is set to "True".
