A freeware 2D CAD program that supports the industry standard DWG/DXF (upto R.2000) format. It’s recently been launched by a company of the same name. It features a graphical interface that bears a remarkable similarity to popular commercial CAD software. AutoCAD command-liners will find it way too basic, but for irregular users, it could be useful. I’d recommend it for viewing, red-lining or printing of drawing files by consultants/clients who otherwise don’t have access to CAD.
