You create a point group by defining its properties.
Point groups organize and identify points that share common characteristics. Use point groups to assign point styles and point label styles for all the points in a point group instead of assigning styles individually.
After you create a point group, do not try to interchange the two methods to make changes to a point group. You can create a point group using the basic method and then change the point group properties using the Query Builder tab. However, you will lose the changes you made on the Query Builder tab if you then change the point group using the Point Groups tab, the Raw Desc Matching tab, the Include tab, or the Exclude tab.
Because the list of points that belong to a point group (the point list) is updated dynamically, you can create point groups either before or after you create points in the drawing. If you create the points first, and then create the point group, the point list of the newly created point group is immediately updated with the existing points that match the criteria for inclusion in the point group. If you create a point group before you create points that qualify for inclusion in the point group, the point group is marked as out-of-date on the Prospector tab as points are created. You can easily update the point list to include the new points. For more information, see .
