Configure Quad Strings

Quad Stringsis one type of Advanced Slice Frameworks.

The Quad Strings advanced framework type lets you define stope faces using two parallel strings: One for the top edge and one for the bottom edge of the stope face. MSO will automatically generate the full stope face by interpolating between these two strings.

This is a very effective method when the top and bottom boundaries of the stope are well defined or extracted from pre-existing engineering or geologic designs. It offers full control over vertical variation while letting MSO handle the interpolation in between.

Here's how it works:

MSO identifies pairs of strings in the selected file.
Each pair defines one stope face: the area between the top and bottom string is filled in automatically.
The resulting tube shapes will be bounded precisely between those string extents in space.
The format and organization of the input string file are essential—strings must be paired correctly.
If needed, users can pre-process string files using Studio tools (e.g., renumbering, filtering).

You might consider this framework in the following scenarios:

Folded or steeply dipping ore bodies where the boundaries are already digitized or well known.
Operations with geologic interpretation lines for stope tops and bottoms.
Where you need to achieve very precise geometry control with minimal complexity.

Activity steps:

Display the Framework screen.
Expand Framework Type to select Advanced Framework, if not already selected.
Expand Advanced Type and select Quad Strings.
Select a String File (...). This file should include the top and bottom strings for each stope face. Usually, a specific structure is expected, such as alternating string numbers or designated attributes to separate top from bottom.
Save your settings.
