Studio 3 Block Modelling - Combining Models

The ability to combine models is a powerful tool of Studio 3 geological modeling.

As well as allowing you to create complex models in simple stages, it also lets you later update and build upon your existing models. Understanding how Studio 3 combines models is therefore important.

For adding models the best option is to use the first model as a prototype for restructuring the second model.

Attribute fields

Any attribute fields such as lithology or grades are handled according to the following rules:

• If the fields are unique to each input model then all these fields are written to the output model. Those fields that do not get a value from either of the input models are set to undefined (-).
• If the same fields exist in both input models the 2nd model overwrites the common fields in the 1st model.

Combining cells

When models are added, the cells are first compared to find how they overlap.

• If cells do not overlap, or overlap exactly, then no cell splitting is done and only the cell attributes are updated.
• If the cells partially overlap then they are split along each cell boundary before updating the attribute fields. As the resulting cells must be rectangular the splitting will continue throughout the full length of a cell.
