Part: Extension of Geometry::Curve to wrap more functions of OCC
Apart from:
bool tangent(double u, gp_Dir&) const;
that was already implemented, now it also implements:
Base::Vector3d pointAtParameter(double u) const;
Base::Vector3d firstDerivativeAtParameter(double u) const;
Base::Vector3d secondDerivativeAtParameter(double u) const;
bool normal(double u, gp_Dir& dir) const;
bool closestParameter(Base::Vector3d point, double &u);
i.e. apart from giving the tangent vector for a given curve at parameter value u,
it also gives:
- The point cartesian coordinates of the curve point at parameter value u
- The vector of the first derivative at parameter value u
- The vector of the second derivative at parameter value u
- The normal vector to the curve at parameter value u
- The parameter value of a curve closest ot a given point
Code cleanup: Changing Trim functionality of Ellipse to use OCC calculations
Part Curve functions extension: closestParameterToBasicCurve
It provides the parameter of the curve closest to a given point. If the curve is a Trimmed curve, the parameter of the basic underlaying curve closest to the point is provided.

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. Home page: http://www.freecadweb.org Documentation wiki: http://www.freecadweb.org/wiki/ Forum: http://forum.freecadweb.org/ Bug tracker: http://www.freecadweb.org/tracker/ Git repository: http://sourceforge.net/p/free-cad/code/ci/master/tree/ 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 heavyweight 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 offeredby 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. Note that autotools build system can still be used but will be obsoleted soon. The pages below contain up-to-date build instructions: For Linux: http://www.freecadweb.org/wiki/index.php?title=CompileOnUnix For windows: http://www.freecadweb.org/wiki/index.php?title=CompileOnWindows For Mac OSX: http://www.freecadweb.org/wiki/index.php?title=CompileOnMac In this folder you will also find additional README files, specific for each platform. Usage ===== The FreeCAD documentation wiki contains sections for each category of users, and a manual, which is a compilation of the most useful articles of the wiki: For users: General FreeCAD usage: http://www.freecadweb.org/wiki/index.php?title=User_hub For power-users: Python scripting: http://www.freecadweb.org/wiki/index.php?title=Power_users_hub For developers: C++ FreeCAD development: http://www.freecadweb.org/wiki/index.php?title=Developer_hub The FreeCAD manual: http://www.freecadweb.org/wiki/index.php?title=Online_Help_Toc
