Convex Hull
Convex Hull creates a surface that envelopes the selected geometries, e.g. a bubble that encloses all selected surfaces/lines/points. This can be used to recreate simplified stopes or ore bodies that were stored as unstructured triangle soups
To use convex hull, select Geometry > Surface Triangulation Tools > Convex Hull.
This is one of the examples where convex hull can be applied:
Select all entities and use Convex Hull and it creates an envelope surrounding the original ore body:
