This Erlang Program converts a DXF (binary or ASCII) to an HTML file. View it in an HTML5-ready browser (Safari, Chromium etc). The DXF file can be created in QCAD (free) http://www.ribbonsoft.com/en/ , AUTOCAD and other CAD systems. Note that a closed pline will be filled in the HTML file. Entities with higher thickness will be on top in the HTML file. 1. Mirror your drawing in the CAD-app down over the X-axis (X=0) 2. Move the drawing up to it's previous position (up above the X-axis) 3. Save as DXF 4. Undo Move and Miror Make sure you have compiled the 3 erl-files, the Erlang command is erlc *.erl In a terminal, type ./dxf2js.sh myfile 0 to create a file myfile.html with a canvas representation of the drawing at layer 0. In a terminal, type ./dxf2js.sh myfile svg to create a file myfile.html with a svg representation of the drawing at layer svg. If you are on a Windows system you have to create a bat-file or run dxf2js module from the erlang console. If you are using QCAD, set the paper size in Drawing Preferences. The parameters to dxf2js.sh is a dxffilename without extension, and a layername If the layer name is svg the output format will be svg, all other layers will be in canvas format. This makes it easy to create a combined svg/canvas graphics. You need to download and install Erlang http://www.erlang.org to run this program. After installation, run erlc *.erl in HTML-vector-graphics directory.
