If you have a text file with data consisting of a point index, x, y, z, and a note, then this utility will organize the data by sorting the points by the value of the note. It creates point or polygon geometry based on user selected points.
The check boxes determine which points to use for import. By default, no points are selected.
The geometry creation buttons are used to create geometry from the selected points.
The layers drop-down and update button 
are
used to select a layer from the active drawing and to update the list of layers
in the active drawing.
The file open button 
is
used to select a text file for processing
If a set of points is selected then the import points
button 
will
import these data points as points.
Use the polygon button 
to
create a single closed polygon from the selected points.
Use the poly-line button 
to
create an open polygon from the selected points.
These
are the view mode toggles. They are used to view the data points as structured
(sorted by note) or as unstructured which shows data as is was read from the
test file.
