Fixes #11873 this was the primary goal of these changes Fixes (partially) #11874 the parts of a polyline are combined as a compound object (shape) but it would be preferable for them to be made into a wire (if possible) Fixes #11872 Objects in a block definition are now kept separately until the block is inserted, in which case the inserted objects are subject to all the other options regarding combining. Fixes (partially, review required) #11871 Text and dimensions are now kept as part of the block definition and are placed in the drawing when the block is inserted but this code has not been extensively tested. Affects #11875, custom types are not made, but the labels now reflect the object types rather than all being "Shapennn" This leaves the importer options handling in a bit of a mess that needs cleanup eventually, but this can be a new issue. This includes some importer flags that have no corresponding options (e.g. import frozen layers), some flags not yet implemented, some flags not yet even declared in the code because their implementation is further off (import hatch outlines), and some suggested future options (import SOLIDs as faces) Centralize the calculation of the OCS for entities as they're read from the DXF. Most of the entities don't use this yet, but some of them roll their own crude Normal Vector handling. Because the new code takes priority over the old for reading the normal vector, such code will always see (0, 0, 1) as the extrusion direction.

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 to change its parameters.
-
Create 3D from 2D and back FreeCAD lets 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, programmer, experienced CAD user, student or teacher.
-
Cross platform FreeCAD runs on Windows, macOS and Linux operating systems.
-
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 packages for stable releases are available for Windows, macOS and Linux on the Releases page.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For development releases check the weekly-builds page.
Other options are described at the wiki Download page.
Compiling
Compiling FreeCAD requires installation of several libraries and their development files such as OCCT (Open Cascade), Coin and Qt, listed in the pages below. Once this is done, FreeCAD can be 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 macOS and other platforms, you will usually have to compile them yourself.
