=================================================== This commit sets the sketch size multiplier OFF by default (so the number of iterations DogLeg/BGFS/LM is not sketch size dependent). In complicated sketches having a high number of parameters, with sketch multiplier on, the number of iterations is extremely high (100 parameters*100 iterations => 10000 iterations). The idea of disabling this comes from tests performed by DeepSOIC and from my own experience using the Sketcher. In general sketch multiplier makes FreeCAD unresposive (very high amount of iterations, not a real freeze) in big sketches so that users end up killing the application. This is preventing the users from taking appropriate action, Developers from getting the information of the failure and users angry. The idea is that even for complicated sketchs N iterations (100 by default) should be enough to converge, if it is ever going to converge. Experience will tell us if we have to increase this number in the range [100-300]. 100 iterations in complicated dossiers is in my experience generally under 30 seconds. N.B.: This commit does not change the defaults stored in your computer, so if you have the sketcher multiplier on, the advanced solver dialog will still enforce this local setting. You may disable it or click the "defaults" button to disable the sketcher multiplier. |

FreeCAD
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:
