In the Block Model step you will be prompted to load your block models from CSV, Surpac (.mdl), Vulcan (.bmf), MineSight (.dat) or Micromine (.DAT) and convert it to Alastri Block Model format (which is .resmodel).
...
Press blue plus icon and import CSV file “.myblockmodel.csv”.
Set the green Header Line to match the header text.
Set the yellow Data Offset to match the first row of data.
Press OK to finish.
...
Once the block model has loaded, its header fields are listed in the Variables panel on the right.
...
Numeric fields use the N(“field”) syntax, and text fields use the T(“field”) syntax.
Drag and drop the variables to the appropriate field (or double click to map to the selected field).
...
Be careful to use the text T(“material”) syntax so that the parcel is read as text, not as a number.
...
Note for Micromine Block Models
When importing Block Models in .DAT format, in the list of Available Variables on the right you will see a new variable MetaN(“Rotation”), which you do not see when working with a CSV file.

Field type | Description | Example |
|---|---|---|
Additive | Additive fields are summed together, such as volumes, tonnes, and gold ounces. |   |
Weight Averaged | Weighted fields are weight-averaged by their parent field, such as iron percent or gold ppm. | |
Text | Text (class) fields create subtotals of their parent fields, such as tonnes of Indicated / Inferred / Measured. |

For example, the block model you are using is in coordinates (2,000 | 297 | 600) x (2,808 | 1, 697 | 900), but you know that only the upper benches will be mined in your schedule, so the data for the lower benches will not be applicable to you. Therefore, you can constrain the data included in the Reserves Model by the Z coordinate, using the formula like "if the benches of interest are above or at 750 meters along the Z axis, report the volume according to the dimensions, otherwise return zero" - "N("Z") >= 750 ? N("DX")*N("DY")*N("DZ") : 0".
...
Generate a new Reserve Model and review the Block Count data, and compare the size of the Reserve Models before and after zeroing in on the unused benches - the values will be significantly lower. Also note that in the Phase Details step, part of the pit will be outside the green box of the Block Model, and the Gap Filling template will be used to calculate its reserves.
