Define Framework Extents

Note: Your MSO framework (the cuboid in which optimal stope shapes are generated and evaluated) must be bound by extents. Use the Orientation screen for this.

You can define your MSO framework extents by either matching the extents of the input block model, or by defining your own cuboid. The extents define the framework coordinate system, which is used to orient slices, prisms, or boundaries during shape generation.

To define framework extents using the input block model:

  1. Create or select an MSO scenario.

  2. If not already defined, specify a block model.

  3. Set up the run economics.

  4. Display the Orientation screen.

  5. Define your Slice, Prism or Boundary orientation settings.

  6. Expand the Framework Extents control group. The contents of this group are identical for all Optimization Methods.

  7. Using Extents Source, select Block Model.

  8. Optionally, view the block model prototype values by checking Show Block Model Prototype.

    Note: You can't edit these fields as they are derived from the input block model.

  9. To see how your framework appears in 3D, check VIsualize in 3D.

    1. To focus the camera on your framework cuboid, click Look At.

  10. Save your settings.

To define framework extents manually:

  1. Create or select an MSO scenario.

  2. If not already defined, specify a block model.

  3. Set up the run economics.

  4. Display the Orientation screen.

  5. Define your Slice, Prism or Boundary orientation settings.

  6. Expand the Framework Extents control group.

  7. Using Extents Source, select Manual.

  8. To start with the existing block model extents, click Copy from Block Model.

    The Manual Extents fields update to show the current model dimensions and rotation values.

    Tip: If you have copied the block model values, it can help to check Show Block Model Prototype for a read-only summary of the existing model settings. This can be a useful reference during editing (say, if you wanted to expand the framework beyond the model without changing the general 3D world position.

  9. It can help to visualize manual extents changes as you make them, so check Visualize in 3D.

  10. Enter or edit the spatial dimensions of the cuboid representing your framework extents. This includes:

    • The X Axis (U Framework Axis) Origin values.

      The 3D display preview updates to reposition the extents at the coordinate specified.

    • For the two remaining axes, define the Distance (the length) of each axis.

    • Repeat editing for the Y and W fields.

    • Repeat for Z and V fields.

    Note: Essentially, the Origin settings represent the lower corner of the optimization volume in world space, and the Distance fields define the size of the extents along each framework axis.

    Tip: Use the mouse wheel whilst editing a field to incrementally increase or decrease values. Using this in combination with the Visualize in 3D option gives you interactive framework sizing, positioning and rotating ability.

  11. Enter framework Rotation values. Up 3 rotations can be specified around any major axis. Note that the rotations are performed in order.

    Note: This is the same rotation convention used for defining a Datamine rotated block model.

  12. Save your settings.
