QUICKEST Process

Display the Find Command screen, locate MODTRA and click Run.
See this process in the Command Table.
Process Overview
Note: This is a superprocess and running it may have an effect on other Datamine files in the project.
The QUICKEST process interpolates grades into a block model using basic calculations. It supports processes requiring precursory interpolation methods, such as IsoShell generation. It can also be called independently from the command line.
