DraftSight is a proprietaryfreeware 2D computer-aided design (CAD) software application developed by Dassault Systèmes. It lets users create, edit and view .dwg and AutoCAD DXF files. The user interface is quite similar to AutoCAD. The standalone, single-user version of DraftSight is free until a user saves or prints a document for the first time. They will then be asked to activate the product within 30 days using a valid email address and reactivate after six months and thereafter at 12-month intervals. Dassault are better known for their 3D CAD software that is widely used in the Aerospace industry and elsewhere.
DraftSight for Windows was released in February 2011 and was downloaded more than 1.8 million times as of December 2011. It is available in 14 languages.
DraftSight allows users to access DWG/DXF files, regardless of which CAD software was originally used to create them, including AutoCAD 2013 from V1R4. According to industry estimates, there are more than three billion DWG legacy files in existence. As stated on its home page, DraftSight uses Teigha Classic for .dwg files and Teigha for .dwg files specifications from the Open Design Alliance to interpret the dwg-file format.
Dassault Systèmes hosts an open, on-line community SwYm (See What You Mean) for DraftSight users. According to Machine Design magazine, engineers are increasingly turning to industry-specific social networking sites to collaborate on projects. The community also holds training resources.
The DraftSight community has an access to a CAD Library with 2D drawings from over 350 component supplier catalogs, including 3M, Advantech, Asco Numatics, Bosch Rexroth, Cepex, CGI, Clippard, DE-STA-CO, Facom, IFM, Igus, INA/FAG, Mädler, Norelem, Nozag, Parker Legris, Pneumadyne, RS Components, Schmersal, Schmalz, Schneider Electric, Sherex and Zimm.
