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.

APTOTRUE is designed to be used in conjunction with processes ANISOANG and  ESTIMA when the apparent dip angle and the true dip direction angle have been interpolated into a model and the true dip angle is required in order to use the Dynamic Anisotropy option to estimate grades.  In fact the input file can be any type of file, so long as it contains the apparent dip and true dip direction fields.

The process takes as input the file IN containing fields APDIP (apparent dip) and TRDIPDIR (true dip direction) and parameter APDIPDIR (apparent dip direction) and calculates the TRDIP (true dip) field which is written to file OUT.  Parameter APDIPDIR is the azimuth of the sections corresponding to the apparent dip field.
