NAME
       imodsortsurf - Sort contours into surfaces or surfaces into objects

SYNOPSIS
       imodsortsurf  [options]  input_model  output_model

DESCRIPTION
       This program can do three different operations related to surfaces.
         1) It can use the mesh produced by imodmesh to analyze the connec-
       tions between contours, and assign each set of connected contours a
       separate surface number.  If you then want the mesh for these objects
       to have the new surface numbers, it is necessary to remesh the objects
       with "imodmesh -S" or the "Surface" option in the "Meshing" panel of
       the 3dmod Model View Object Edit dialog.
         2) It can analyze a mesh in an object without contours (such as is
       produced by saving an object from the isosurface display in 3dmod
       Model View) and sort it into separate, unconnected surfaces, each with
       a different surface number.
         3) It can place each surface into a separate object.  This operation
       can be done either on existing surfaces or on the surfaces produced by
       analyzing the mesh.  It works by moving the contours themselves for a
       conventional object, or by moving the mesh components for an object
       without contours.  When contours are moved, the objects must all be
       meshed to see the surfaces.

   OPTIONS
       -o list
              Restrict the sorting to objects in the given list of object num-
              bers, which can consist of a comma-separated set of ranges.  The
              default is to do all objects.

       -s     Split surfaces into new objects.

       -e     Use existing surfaces when splitting them into new objects.  The
              default is to analyze the surfaces from the mesh instead.  With
              this option, no mesh is required.

       -c     Make new objects the same color as the object from which they
              are derived.  Most other display properties are transferred from
              the existing object to the new object.

       -k     Keep the surface numbers when moving contours into new objects.
              The default is to set surface numbers to zero.

BUGS
       When surfaces are split into new objects, contour and surface labels
       will be lost.  Also, stored view information will not be copied to the
       new objects.
