AutoCAD is a computer aided drawing software, created in December 1982 by Autodesk. Although it was originally developed for mechanical engineers, it is now used by many and is currently the most widespread CAD software in the world.

Hence its DWG file format has become the standard for industrial designs in 2D, so we provide you with the technical drawings of our products in this format.

To edit DWG files, you can use the freeware DraftSight
