* Removed unnecessary use of FreeCAD.Vector. Renamed some functions and variables for clarity (in this description the new names are used). Reformatted the code. Moved imports to the top of the file. Updated the tooltips. Tweaked the title text "Parameters ...". * Fixed the length of list properties bug. * Flip direction did not work properly. The adopted solution is to reverse the edges the roof is based on. * Added support for consecutive parallel edges. * Added support for zero angle roof segments. * The code now handles zero length runs without throwing an error. * To handle triangular roofs with a zero length eave, "eave" (egde) has been turned into "eavePtLst" (list of points). * The ridges of opposite parallel roof segments (if they do not use a relative profile) are recalculated if the sum of their runs is larger than the distance between their edges. The old version of the command would do this only if segments connected to gables and only properly if the corners between the edges of the segments and the gable were 90 degrees. * Revised backGable and nextGable. They now call helperGable. * Revised the 6 other back/next functions. They now call helperSloped. This also fixes several cases where cookie-cutter outlines (profilCurr["points"]) were wrong. In nextHigher, backHigher, nextLower and backLower a point was wrongly projected on the X-axis. In nextHigher the point on the higher ridge was wrongly included. * Improved the cookie-cutter outlines for roof segments with lower overhangs and higher ridges in corners. * Data from a relative profile is no longer used if it in turn references a relative profile. * Changed the default idrel to -1 and changed calcMissingData to not process this value. This avoids confusion for users who are unaware of the relative profile feature. * Introduced find_inters as a workaround for DraftGeomUtils.findIntersection. The latter finds intersections for parallel lines that share a point. Find_inters uses a modified version of getLineIntersections from DraftGeomUtils.findIntersection. * Calling DraftVecUtils.removeDoubles later in the program flow as it does not compares the first and the last vector. * Avoided the QTreeWidget scrolling to the top on every change, by not clearing it but updating existing items instead. * Added self.tree.setRootIsDecorated(False). This gets rid of the 1st column's extra left margin. Removed item.setTextAlignment(0,QtCore.Qt.AlignLeft) as this did not work.

Overview
-
Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.
-
Create 3D from 2D & back FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production ready drawings.
-
Designed for your needs FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture. Whether you are a hobbyist, a programmer, an experienced CAD user, a student or a teacher, you will feel right at home with FreeCAD.
-
Cross platform FreeCAD runs on Windows, Mac and Linux
-
Underlying technology
- OpenCASCADE A powerful geometry kernel, the most important component of FreeCAD
- Coin3D library Open Inventor-compliant 3D scene representation model
- Python FreeCAD offers a broad Python API
- Qt Graphical User Interface built with Qt
Installing
Precompiled (installable) packages are available for Windows and Mac on the Releases page.
On most Linux distributions, FreeCAD is directly installable from the software center application.
Other options are described at the wiki Download page.

Compiling
Compiling FreeCAD requires installation of 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 convenient 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:
Usage & Getting help
The FreeCAD wiki contains documentation on general FreeCAD usage, Python scripting, and development. These pages might help you get started:
The FreeCAD forum is also a great place to find help and solve specific problems you might encounter when learning to use FreeCAD.
