This registry entry determines the first technique that will be used for your advanced scan. The options are Line, Body Axis, Variable, and Nullfilter.
Line (0) technique - The approach of the probe is perpendicular to the line between the previous two hits.
Body Axis (1) technique - The approach of the probe is perpendicular to the indicated axis (see ScanDialogBodyAxis).
Variable (2) technique - The approach of the probe is perpendicular to the line between the previous two hits, but additional calculations are made using the min/max increments and angles to determine increments between hits.
Nullfilter (3) technique - Data is not filtered.
Entry Name: ScanDialogDirTech1
