 UWALS                                                         Non-menu command
 ==============================================================================
 This command updates the database of axial walls that were created by the
 system prior to V4.11-R6.

 Description:
 In Version 4.11 Release 6, changes were made to the association between axial
 walls and their three dimensional model.
 This was done in order to maintain certain wall characteristics, despite
 operations such as sectioning or set operations on them. This was also done to
 enable the deletion of 3D solid walls and re-extension of them to 3D, as well
 as to enable selection or query by indicating the wall's solid instead of its
 axis.
 NOTE: Run this command only once for each file!
