LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Unix/Linux, macOS, and Windows operating systems.. 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.
The LibreDWG project has resumed active development, including the addition of more recent .dwg and .dxf formats with version 0.5 in June of 2018. [12] The most recent release as of November 2020, version 0.12.5 includes read support for all DWG formats r13+, write support for r2000 DWG and read/write support for all r13+ DXF versions. [13]
FreeCAD's support for the proprietary DWG file format has been problematic due to software license compatibility problems with the GNU LibreDWG library. 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.
The table below provides an overview of notable computer-aided design (CAD) software. It does not judge power, ease of use, or other user-experience aspects. The table does not include software that is still in development (beta software). For all-purpose 3D programs, see Comparison of 3D computer graphics software.
Apart from DWG support, files can be exported to DXF. Gstarsoft has also released versions for mobile devices called GstarCAD MC which runs on iOS [ 5 ] and Android. [ 6 ] GstarCAD's GRX API means that software written for AutoCADs ARX API can run on both without changes to the code.
Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.
DWG is merely descriptive of applicant's goods under Section 2(e)(1) of the Trademark Act for two reasons: (1) DWG is a recognized abbreviation for "drawing," and (2) .dwg is a file format used for computer-aided design (CAD) drawings made both with applicant's CAD software and others' CAD software. Autodesk appealed the decision.
