Block Model

ThisA Block Model entity stores astructured raw3D Blockblock Model.data—typically Thisused in resource estimation, geological modeling, and spatial analysis. The model is uploaded as a comma-separated ASCII text file,file, where each row represents an individual block.

Uploading a blockBlock inModel

1. Navigate to your project’s Catalog section and click “Add Object.”
2. From the model.

   Once youdropdown, select “Block Model”Model.”

from the “Add Object” button menu, you will see the following options:

3. Fill out the following fields:

Units for X and Y coordinates (e.g., meters, feet).

 

Vertical Units

Units for Z coordinates (e.g., meters, feet).

 

CSV Header

The CSV Header field defines how each column in your file should be interpreted. For instance,example, ifa theheader suppliedline CSV Header is “like:
XC,YC,ZC,XL,YL,ZL,AU,CU”, the following fields CU

Column Types

Each entrycolumn in the “Column Definition” canmust be usedassigned toa tellType, which tells the system how the values in that column should be processed. There are two fields to provideprocess init:

Block CentroidOrigin YX/Y/Z	YCoordinates coordinate offor the block’s centroidorigin corner.
Block CentroidDimension X/Y/Z	Z coordinateSize of the block’sblock centroidalong each axis.

Note: You must choose either block centroids or block origins for positioning—not both. Using both will result in an input error.

 

Level of Detail (LOD) Aggregation

Each numeric column (e.g., grades or quantities) can also be configured with a Level of Detail (LOD) operation, which determines how values are aggregated in lower-resolution views:

LOD Option	Description
Average	Average of all higher-resolution values.
Block Origin XMin	XMinimum coordinatevalue offrom the block’sfiner origindata.
Block Origin YMax	YMaximum coordinatevalue offrom the block’sfiner origindata.
Block Origin ZAdd	Z coordinateSum of theall block’svalues origin(ideal for counters).
Block Dimension XMultiply	Block’sProduct dimensionof alongall the X axis
Block Dimension Y	Block’s dimension along the Y axis
