All technical 2D drawings created can be printed to scale from A4 up to A0 size, saved in native AutoCAD file format or exchanged with other CAD programmes using the DXF file format. Accurate 2D drawings can be opened in Trimble SketchUp and easily 'push - pulled' into 3D models.
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 DXF is primarily 2D-based and its format is a tagged data representation of all the information contained in an AutoCAD drawing file, which means that each data element in the file is preceded by an integer number that is called a group code indicating the type of following data element.
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).
OpenSCAD views and models can be exported to many different formats. Including: Views: can be exported in PNG format. 2D models can be exported in SVG, AutoCAD DXF, and PDF. 3D parts can be exported in 3MF, AMF, OFF, and STL as simple volumes. [12] There is no color, material, or parts definition in the exported model. [citation needed]
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.
FreeCAD is a free and open-source application that can work with the DWG files by using the proprietary ODA File Converter for .dwg and .dxf files from the Open Design Alliance (ODA). [55] The ODA also provides a freeware stand-alone viewer for .dwg and .dgn files, ODA Drawings Explorer, which runs on Windows, Linux, and Mac OS X.
