pkv 949df2b64b 0025509: Wrong shape considered as valid by checkshape
New features:

1. class BRepCheck_Solid
The class is to check a solid per se.
The scan area is:
 i.  Shells that overlaps each other
     Status:  BRepCheck_InvalidImbricationOfShells

 ii.  Detached parts of the solid (vertices, edges)
       that have non-internal orientation
       Status:  BRepCheck_BadOrientationOfSubshape

 iii.  For closed, non-internal shells:
 iii.1 Shells containing entities  of the solid that
      are outside towards the shells
      Status:  BRepCheck_SubshapeNotInShape

 iii.2 Shells that encloses other Shells
     (for non-holes)
      Status:  BRepCheck_EnclosedRegion

Changes:

1. enumeration BRepCheck_Status
members:
 InvalidImbricationOfShells,
 EnclosedRegion,
has been added

2. class BRepCheck
method:
void BRepCheck::Print(const BRepCheck_Status stat,
                      Standard_OStream& OS)
has been modified to take into account II.1

3. class BRepCheck_Analyzer
method:
void BRepCheck_Analyzer::Put(const TopoDS_Shape& S,
                             const Standard_Boolean B)
has been modified to take into account I.1

4. class BRepTest
function:
void StructuralDump(Draw_Interpretor& theCommands,
 const BRepCheck_Analyzer &theAna,
 const Standard_CString   ShName,
 const Standard_CString   Pref,
 const TopoDS_Shape       &theShape)
has been modified to take into account I.1, II.1

Open CASCADE Technology
=======================

This directory contains sources of Open CASCADE Technology (OCCT), a software
development platform providing services for 3D surface and solid modeling, CAD 
data exchange, and visualization. Most of OCCT functionality is available in 
the form of C++ libraries. OCCT can be best applied in development of software 
dealing with 3D modeling (CAD), manufacturing / measuring (CAM) or numerical 
simulation (CAE).

modify it under the terms of the GNU Lesser General Public version 2.1 as 
published by the Free Software Foundation, with special exception defined in 
the file OCCT_LGPL_EXCEPTION.txt. Consult the file LICENSE_LGPL_21.txt included
in OCCT distribution for complete text of the license.

Packaging
---------

You can receive certified version of OCCT code in different packages.

- Snapshot of Git repository: contains only bare sources of OCCT; many C++ 
  files, HTML documentation, and project files / makefiles for building OCCT
  need to be generated.

- Complete source archive: contains all sources of OCCT, including C++ files
  generated by WOK, HTML and PDF documentation, and projects / makefiles for 
  building on all officially supported platforms.

- Binary package (platform-specific): in addition to complete source archive, 
  it includes binaries of OCCT and third-party libraries built on one platform. 
  This package allows using OCCT immediately after installation.

Certified versions of OCCT can be downloaded from http://www.opencascade.org

You can also find OCCT pre-installed on your system, or install it from 
packages provided by a third party. Note that packaging and functionality
of such versions can be different from certified releases. Please consult 
documentation accompanyog your version for details.

Documentation
-------------

Open file doc/html/index.html to browse HTML documentation.

If HTML documentation is not available in your package, you can:

- Generate it from sources. 

  You need to have Tcl and Doxygen 1.8.4 (or above) installed on your system.
  and accessible in your environment (check environment variable PATH).
  Run batch file *gendoc.bat* on Windows or Bash scriot *gendoc.sh* on Linux
  or Mac OS X to (re)generate documentation.

- Read documentation in source plain text (MarkDown) format found in 
  subfolder *dox*

See *dox/dev_guides/documentation/documentation.md* for details.

Building
--------

In most cases you need to rebuild OCCT on your platform (OS, compiler) before
using it in your project, to ensure binary compatibility.

Consult the file *dox/dev_guides/building/building.md* for instructions on
building OCCT from sources on supported platforms.

Version
-------

The current version of OCCT can be consulted in the file
*src/Standard/Standard_Version.hxx*
