Also, you can tag individual members within a feature set so that they are not used. To tag a member of a set to not be used in the best fit alignment, clear the check box to the left of the feature in the Alignment features list box in the Best Fit Alignment dialog box (Insert | Alignment | New | Best Fit button). If a check box for a basic scan is cleared, it and all of its associated points will not be used in the calculations.
