The CAD drawings on this website were produced using LibreCAD open source software and are in DXF file format. If you already have CAD software on your computer
then it will be able to open this type of file. If you do not have CAD software, and want to view the drawings, LibreCAD is the recommended programme for
doing so. It is free and works exactly as you would expect from a professional 2D CAD programme.
LibreCAD is available for Linux, Windows and macOS operating systems and can be downloaded from the project's website
