emv 92ae0f2fe3 0025232: Functionality to create solids from set of shapes
Purpose:
The algorithm is to build solids from set of shapes.
It uses the BOPAlgo_Builder algorithm to intersect the given shapes and build the images
of faces (if needed) and BOPAlgo_BuilderSolid algorithm to build the solids.
Steps of the algorithm:
1. Collect all faces: intersect the shapes if necessary and collect  the images of faces,
   otherwise just collect the faces to the <myFaces> list.
   All faces on this step added twice, with orientation FORWARD and REVERSED;
2. Create bounding box covering all the faces from <myFaces> and create solid box from corner points
   of that bounding box (myBBox, mySBox). Add faces from that box to <myFaces>;
3. Build solids using faces from <myFaces> using BOPAlgo_BuilderSolid algorithm;
4. Treat the result: Eliminate solid containig faces from <mySBox>;
5. Fill internal shapes: add internal vertices and edges into created solids;
6. Prepare the history.

Fix for regression.
class BOPAlgo_BuilderSolid:
The tolerance value used in BRepClass3d_SolidClassifier has been increased.

Test cases for issue CR25232

Small correction to eliminate the warning.

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

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*
