Selecting packed objects for display
When lines are packed, one of the packed lines is always designated the master packed line. If the TCVIS_Selection_From_Viewer preference is set to true, you can select packed objects in the viewer using the buttons available in the 3D Selection toolbar. However, if you select the master packed line, all packed lines are selected. If you do not want this behavior, you must unpack the packed lines before selecting the individual objects in the viewer.
