A request also went to the FSF to relicense GNU LibreDWG as GPLv2 or LGPLv3, which was rejected. Open CASCADE technology was contacted by Debian team in 2009, and 2012 got a reply that Open CASCADE technology was considering dual-licensing OCCT (the library), however they postponed that move. As FreeCAD (and also LibreCAD) has dependencies on Open Cascade, which prior to version 6.7.0 was only compatible with GPLv2, it couldn't use the GNU LibreDWG library as GPLv2 and GPLv3 are essentially incompatible.

The GNU LibreDWG library started as a real free alternative to the source-available OpenDWG library (later Teigha Converter and now ODA File Converter) and is licensed under the GPLv3.

DWG support įreeCAD's support for the proprietary DWG file format has been problematic due to software license compatibility problems with the GNU LibreDWG library. īesides FreeCAD's own file format, files can be exported and imported in DXF, SVG (Scalable Vector Graphics), STEP, IGES, STL (STereoLithography), OBJ (Wavefront), DAE (Collada), SCAD (OpenSCAD), IV (Inventor) and IFC. Other files include brep-files for objects and thumbnail of drawing. GuiDocument.xml then has visual representation details of objects. xml file has all geometric and parametric objects definitions.

It is a standard zip file that holds files in a certain structure. Supported file formats įreeCAD's own main file format is FreeCAD Standard file format (.FCStd). Īs of late 2020, 3D Models searcher of CADENAS called is integrated into FreeCAD. There are moves to expand FreeCAD in the architecture, electrical, and construction (AEC) engineering sectors and to add building information modeling (BIM) functionality with the Arch Module. FreeCAD itself can also be used as a library by other programs. However, the modular nature of FreeCAD allows the user to adapt its workflow for such environments via the use of plugins.įreeCAD uses open-source libraries from the field of computing science among them are Open CASCADE Technology (a CAD kernel), Coin3D (an incarnation of Open Inventor), the Qt GUI framework, and Python, a popular scripting language. Under its current state, direct 2D drawing (like AutoCAD LT) is not the focus for this software, and neither are animation or 3D model manipulation (like Blender, Maya, or Cinema 4D).

It is intended to be a feature-based parametric modeler with a modular software architecture, which makes it easy to provide additional functionality without modifying the core system.Īs with many modern 3D CAD modelers, FreeCAD has a 2D component to facilitate 3D-to-2D drawing conversion. Users can extend the functionality of the software using the Python programming language.įreeCAD features tools similar to CATIA, Creo, SolidWorks, Solid Edge, NX, Inventor, Revit, and therefore also falls into the category of building information modeling (BIM), mechanical computer-aided design (MCAD), PLM, CAx and CAE.

FreeCAD is free and open-source, under the LGPL-2.0-or-later license, and available for Linux, macOS, and Windows operating systems. It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical engineering. Interior of 3D house Arduino board imported from Eagle PCB softwareįreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support.
