Description

Evaluate all visible string overlay objects, against either a block model or drillholes,by projecting them perpendicular to the view plane.

All strings will be evaluated regardless of their selection status, although strings that are not displayed due to filtering will not be included in the analysis.

Strings can be in any position, and can be coplanar. This command, effectively, will run the evaluate-1-string command multiple times in order to prepare results for either individual evaluation blocks, or a combined volume comprising all extruded strings.

Strings will be internally extruded to form a 3D volume for analysis. This projection will take place orthogonally to the current section plane, and is unaffected by the current view direction or rotation.

If multiple strings exist, you will be able to report the evaluation results for each closed/projected string volume or as a combined result.

 

How to use

  1. Run the command.

  2. In the Evaluation Settings dialog, set the Near Projection Distance. This is the distance 'out of the screen' that the selected string(s) will be projected in order to form a volume.

  3. Similarly, set the Far Projection Distance. This is the distance 'into the screen' that the selected string(s) will be projected in order to form a volume.

  4. Set the First BlockID identifier. This will be assigned to the model blocks encompassed by the volume of the first selected string. It will be incremented for other string entities automatically, using the BlockID Increment.

  5. Set a Default Density value: this will be used if a Density field does not exist in the input model, or it exists and absent values are found. By default, this is 1.

    The Default Density setting persists between the static evaluation commands, but can be adjusted in any of them, if appropriate.

  6. Click OK to display the Evaluation Results panel. This shows the tonnes and volume for each distinct string entity. By default, each string is reported as a separate block of results, but these can be combined using the Combine Block Results command.

The evaluation results can be saved to a new object using the Save Results option in the results dialog. It will then be listed in the Loaded Data control bar. Any existing evaluation results of the same name will be overwritten.

The evaluation results, specifically the fields listed in the output results table and which have been selected from the evaluated drillholes or block model, are not effected by the order in which data has been loaded.
