No, you do not need the drillhole extension on your Oasis montaj subscriptions in order to use the VOXI drillhole constraint builder. Any Geosoft database that has X, Y, Z, and either susceptibility or density channels, can be used to build a VOXI set of drillhole constraint voxels.
Do I need to be licensed for the drillhole extension to use the drillhole constraint builder in VOXI?
