Issue: How do I export a block model from Surpac to Whittle?



Additional Details: To export a Surpac .mdl file and import into Whittle you need to either: 





Save the block model as a string file.



You will need the following attributes for the block model:   



An attribute containing the grade value for every block in the model. These values must exist as a fraction of the "units"/tonnes, with a zero grade usually denoting an air or waste block. An attribute with a rock code. This attribute can be either a character or an integer attribute. A specific gravity attribute is also required.



In addition, the following attributes must exist for some (but not all) Whittle products:  



Whittle Four-D and Four-X require a Mining Cost Adjustment Factor (MCAF). Whittle Four-D and Four-X require a Processing Cost Adjustment Factor (PCAF).
