This command defines the full name, value range and value type of attributes. This allows StrataCalc commands to identify invalid attributes that fall outside the minimum and maximum value range. Incorrect data entry is detected in Place Drillhole and Drillhole Data Sheet. Use the Attribute Validation Report command under Drillhole, to detect invalid attributes in the existing drillholes. This routine also defines non-numerical attributes that the program treats as a string and not a number. An example of a non-numerical attribute would be strata color. Non-numeric attributes need to be defined as such before importing the drillholes, otherwise the attribute values, such as green or red, will not import correctly. The Number of Decimal Places is used in the Draw Drillhole Text command. The attribute definitions are stored in a file with an .ATR extension.
