Many times the lab analysis is received long after the structure data for new drillholes has been entered. This command imports attribute data from a text file into drillholes that are already existing in the drawing. Besides the attribute values, the text file must include the drillhole name or the drillhole northing and easting and a strata or bed name, from and to, or elevations. These values are used to locate where to assign the attribute values.
The order of the columns is set in the dialog shown below. To add one of the standard column types, highlight the name from the Available list and click Add. To add an attribute, click the Add Attribute button. Another dialog will appear for entering the attribute name.
To assign qualities to the drillhole by strata elevation, the program needs both the top and bottom elevation of the sample. This can be done by 2 elevations, by 2 depths or by elevation and thickness. If the sample doesn't match up with what is in the drillhole, it will split the strata and beds to match up with the sample interval from the quality file. To alleviate this, just use bed name instead of an interval to match up.
