- ArcOfEllipse enhancement: Tangency ArcOfEllipse to ArcOfEllipse or ArcOfCircle by selecting end/starting points... - Minor bug corrections (Thanks DeepSOIC) - ExposeInternalGeometry python command - DeleteUnusedInternalGeometry python command - On deletion of an Ellipse/ArcOfEllipse all further unconstrained internal geometry is also deleted. - This cleans up the code by eliminating code repetition in the creation methods. - Major bug fix for autoconstraints for ellipse and arc of ellipse creation (for both creation methods) - Major bug fix Start and Endpoint constraints of an arc of ellipse where not taking into account that Sketcher arcs are always CCW, so they have to be exchanged if we convert a CW arc into a CCW arc. Sketcher: General bug fix: Tangency wrongly suggested What? ===== - On creation of a shape autoconstraints are suggested. - Tangent autoconstraint was suggested even with lines perpendicular to the tangency direction Reproduce ========= - Make a circle on the origin and move the mouse along the X axis, it will suggest a tangency that is impossible - Click on the axis and no circle will be created Solution ======== - The SeekConstraint now can use the parameter dir to give a direction that is substantially perpendicular to the expected tangency, so that if an object having a direction (a line) is hit, a tangency will not be suggested if within around 6 degrees of being parallel. - Additionally, if such a line is an X,Y axis of the sketch, tangency will only be suggested if the direction is within 6 degrees of being perpendicular (i.e. it is almost tangent already while sketching). - This difference is due to the fact that an X or Y axis can not "move" to meet the object under creation, whereas a line can.
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.

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
