Abdullah Tahiri 224b3ec7d7 Sketcher: Improvement: Horizontal/Vertical Autoconstraint creation with External Geometry 
=====================================================================================

This fixes a bug related to:
http://www.freecadweb.org/tracker/view.php?id=2093

that during creation of a geometric element if a vertical/horiz autoconstraint is to be enforced, it is not enforced if the endpoints of the geometric element under creation are
coincident with external geometry.

According to the discussion here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12254&sid=eacf5bdee068cb71cc54dc5a62a6849d&start=20#p99359

this fixes the bug.

It does not fulfil the request on the ticket as it was decided to still allow an explicit addition of a vertical/horizontal constraint, as
it may be needed in some cases and the user expects to be able to add them, even if it will lead to an overconstrained sketch.

How to reproduce?
1. Create a rectange
2. Pad it
3. Create a new sketch on a face
4. link two corners as "external geometry" (but not the ones of a diagonal)
5. Create a line coincident with the first and second corners, so that the line is horizontal or vertical

In master it will force horiz or vert leading to a overconstrained sketch.
With this patch, the horiz/vert will not be enforced in this case.

FreeCAD

screenshot

FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source (LGPL2+ license) and extremely modular, allowing for very advanced extension and customization.

FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX, BSD and Linux platforms.

Installing

Precompiled (installable) packages are usually available to you from several sources and are described on the FreeCAD download page:

http://www.freecadweb.org/wiki/index.php?title=Download

Compiling

Compiling FreeCAD requires to install several libraries and their development files such as OpenCasCADe, Coin and Qt, listed in the pages below. Once this is done, FreeCAD can be simply compiled with cMake. On windows, these libraries are bundled and offered by the FreeCAD team in a convenience package, on Linux they are usually found in your distribution's repositories and on Mac OSX and other platforms you will usually need to compile them yourself.

The pages below contain up-to-date build instructions:

For Windows: http://www.freecadweb.org/wiki/?title=CompileOnWindows

For Mac OSX: http://www.freecadweb.org/wiki/?title=CompileOnMac
