If you are a new user some general information about GEOM usage are given here:
\subpage first_steps_guide

\b Geometry module of SALOME is destined for: 
- \subpage import_export_geom_obj_page "import and export of geometrical models"
  in IGES, BREP and STEP formats;
- \subpage create_geom_obj_page "construction of geometrical objects"
  using a wide range of functions; 
- \subpage view_geom_obj_page "viewing geometrical objects" in the OCC
  viewer; 
- \subpage transform_geom_obj_page "transformation of geometrical objects"
  using various algorithms;
- \subpage repairing_operations_page "optimization of geometrical objects";
- viewing \subpage geometrical_obj_prop_page "geometrical object properties"
  and other information about geometrical objects using 
  \subpage using_measurement_tools_page "measurement tools";
- \subpage pictures_page "designing shapes from pictures";
- easily setting parameters via the variables predefined in
  \subpage using_notebook_geom_page "SALOME notebook".

Geometry module preferences are described in the
\subpage geometry_preferences_page section of SALOME Geometry Help.

Almost all geometry module functionalities are accessible via
\subpage geompy_page "Geometry module Python Interface"

Other functions are available in <a class="el" target="_new" href="../../tui/GEOM/docutils/index.html">salome.geom python package</a>.
