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 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).
SolveSpace workflow starts either with opening an existing file or creating a new one and usually involves sketching. The basic shapes of a new physical part is sketched out and constrained to specific dimensions and locations. When the model is complete, it is either exported to one of the supported CAD formats or into a document for further ...
It provides connectors between shapes, which are available in a range of line styles and facilitate building drawings such as flowcharts. It also includes features similar to desktop publishing software such as Scribus and Microsoft Publisher, [25] but the features are not on par with desktop publishing software. [26]
In 2009 a license update of LibDWG/LibreDWG to the version 3 of the GNU GPL, [6] made it impossible for the free software projects LibreCAD and FreeCAD to use LibreDWG legally. [5] Many projects voiced their unhappiness about the GPLv3 license selection for LibreDWG, such as FreeCAD, LibreCAD, Assimp, and Blender. [7]
CAD data exchange is a method of drawing data exchange used to translate between different computer-aided design authoring systems or between CAD and other downstream CAx systems. [1]: 157 Many companies use different CAD systems and exchange CAD data file format with suppliers, customers, and subcontractors. [2]
DWG (from drawing) is a proprietary [3] binary file format used for storing two- and three- dimensional design data and metadata. It is the native format for several CAD packages including DraftSight, AutoCAD, ZWCAD, IntelliCAD (and its variants), Caddie and Open Design Alliance compliant applications. In addition, DWG is supported non-natively ...
Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
