Tag Non-Surface Points

This command allows you to tag Carlson points in the drawing so that they will not be used when creating a surface.  These could be points that are far from the site, such as off-site horizontal control, or points with elevations that are not on the ground, such as a TBM taken on the top of a fire hydrant.  There are several methods available to select the points for tagging as non-surface points.  One key to remember is that they must be present in the drawing to be tagged.

Range:  This option allows you to specify a range of point numbers, or select ALL of the points currently in the drawing, or specify a Point Group, remembering, however, that only points that are currently in the drawing can be tagged.  So if you select a Point Group, but only some of the points listed in the Point Group are currently present in the drawing, the whole Point Group will not be tagged

Area:  This option allows you to utilize inclusion and/or exclusion polyline(s) to specify an area in the drawing within which any points currently in the drawing are tagged as non-surface points.

Selection Set:  This option allows the manual selection of points within the drawing.

Description Match:  This option allows the filtering of selected points by descriptions.  For example, you could use a Range of ALL, but set the Description Match to TBM, and only the points with that description would be tagged.
