LibreCAD is available in over 30 languages. The problem was eventually resolved by writing a new GPLv2-licensed library called libdxfrw, with more complete DWG support. A request also went to the FSF to relicense GNU LibreDWG as GPLv2, which was rejected. The GNU LibreDWG library is released under GPLv3, so it cannot be used by GPLv2-licensed LibreCAD (and FreeCAD) because their licenses are incompatible. LibreCAD relies on a GUI based on Qt5 libraries, so it can run on several platforms in the same way. Originally, the GUI was based on Qt3 libraries. Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience in this type of commercial CAD application.Īround 2010, the QCAD Community Edition v2.0.5.0 was forked to start the development of what is now known as LibreCAD. It is free and open-source, and available for Linux, macOS, and Windows operating systems. You can freely enter Python commands yourself if you need a little more flexibility, or even create macros by recording any particularly useful Python for replay later.LibreCAD is a computer-aided design (CAD) application for 2D design. Everything you do within the interface will issue some Python command, which you can examine. There are also plenty of mesh tools a drawing module which exports projected views of your geometry to a 2D SVG document and a raytracing module which exports your work for rendering in POV-Ray.Īnd Python code underlies all of this. FreeCAD supports 2D objects like lines, rectangles, arcs or circles, as well as various 3D primitives (box, sphere, cylinder, cone, torus), each of which can then be manipulated in various ways (translation, rotation, mirroring, scaling, offset and more). If you've samples to hand then FreeCAD can already import DXF, OCA/ GCAD, SVG, STP/ STEP, IGS/ IGES and other formats, a quick way to get started and see what the program can do.īut if you prefer then you can also create a new document from scratch. The program's 0.12 version number tells you it's not yet ready for prime time, but if you're interested in this area - particularly if you're familiar with Python scripting - then there's already plenty to explore here. FreeCAD is a powerful 3D CAD modeler and drawing tool which is targeted squarely at the mechanical engineering and product design fields.
