Isosurface
You can create isosurfaces to visualize results in a stress grid box.
Select: Interpret > Isosurfaces
The isosurface is a surface representing points of constant value with the box. The user specifies the value and the data type it is associated with. Isosurfaces are locked to a particular data type and don't change when the global data type combo changes.
Below shows an example of an excavation tunnel with isosurface.
