Interrogation

Use the Interrogation tab of the Block Model Properties define the mappings between the fields of the Block Model and the attributes of one or more design layers.

This is a prerequisite to using the Interrogate Block Model utility on the Triangulation tab, in the Utility group.

Defining the Interrogation Attribute Mappings

In the screenshot below, notice that there are 10 attribute mappings, 5 fields are repeated and separated in High Grade and Low Grade groups. The Filter Condition is then used to only write to the respective attribute when the GradeBin Block Field is the correct category: HG – High Grade, LG – Low Grade. This is the main use case for Filter Conditions.

Always ensure that every enabled attribute mapping has a valid Attribute, a valid Field, and a valid Filter Condition (if Use Condition is checked). Any attribute mappings that are not set up correctly will either not be executed in the interrogation or prevent the interrogation entirely.

Note the order of attribute mappings is only ever important if two attribute mappings are writing to the same attribute. In this case there could be overwriting happening and the attribute will have the value of the last attribute mapping in the grid (assuming no grid column sorting, or filter conditions are involved).

Enable

Use this check box to enable or disable this mapping during interrogation.

Attribute

Select an attribute to map to a block model field.

Field

Select the block model field to map to the specified attribute.

Use Condition

Select this check box to use the Filter Condition (if one has been specified). See the example described above.

Use the local toolbar to manage the list attribute mappings:

	Add a new item to the list.
	Delete the item(s) currently selected in the list.
	Move the currently selected item(s) Up to reorder the list.
	Move the currently selected item(s) Down to reorder the list.

Note the order of attribute mappings is only ever important if two attribute mappings are writing to the same attribute. In this case there could be over writing happening and the attribute will have the value of the last attribute mapping in the grid (assuming no grid column sorting, or filter conditions are involved).
