Displaying Search Ellipses as Solids in GEOVIA GEMS

By

Since the release of GEOVIA GEMS™ 6.7.4, previewed search ellipses can now be saved as solids. Resource Geologists can display the triangulations to validate or improve search ellipse definitions before interpolating a block model.

To preview a search ellipse and save it as a solid, users may follow these steps:

1. On the Tools menu, point to Geostatistics, and then click Preview Search Ellipse.
2. In the Search Ellipsoid window, select the Block workspace and the Search-ellipse profile from the drop-down. An ellipsoid can be defined by Azimuth/Dip/Azimuth or by Rotation ZXZ/ZYZ.

  • Use a trace-block profile
