Abdullah Tahiri 47c0859c1b Sketcher: Bug fixes: inability to create links to external geometry 
=================================================================

First bug: Inability to create links to external geometry as described here:
http://forum.freecadweb.org/download/file.php?id=16668

Second bug: FC crashes on changing the support after having imported external geometry as described here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12380

and solving this ticket:
http://www.freecadweb.org/tracker/view.php?id=2225

Solution to first bug:

If for some reason a sketch ends up having a list of external geometries (property) that can not be recreated (rebuilt),
they remain latent, do not show the external elements in the elements widget or in the screen and prevent adding the
elements again.

In cases where the saved file contains invalid external geometry links (which will give raise to a handled exception that would prevent external geometry creation),
this condition gets detected during restore and the invalid links are deleted before external geometry creation, so as to allow the rest of external links to be recreated.

Solution to second bug:

It is also related to invalid external links (the link was existing, but upon change on the support, it is possible that an external edge is no longer valid, reduction of edges in support).
This situation is detected upon entering into edit mode, and the invalid ones are deleted.

Note that there is still the possibility for the user to remap an invalid sketch BEFORE editing, if the remapping is successful, it may not be necessary to delete links (all depends on the
specific 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

For Cygwin: http://www.freecadweb.org/wiki/?title=CompileOnCygwin
