• QCad with terminal tools (http://www.qcad.org/en/qcad-downloads-trial)

Adding to your existing Alfresco Project

1. Build the project and install it on your local Maven repository using mvn clean install

2. Add the following as a dependency in your repository AMP module.

   <dependency>
       <groupId>se.loftux.modules.vector-transformations</groupId>

       <type>amp</type>
   </dependency>  

• Add additional overlay configurations necessary based on the Maven archetype being in the project.

Configuration

1. Copy dwg2bmp_alfresco_fallback and dwg2svg_alfresco_fallback in containing folder for dwg2bmp and dwg2svg from QCad.
2. Specify paths in alfresco-global.properties

Example configuration:

#DWG -> PNG, SVG
dwg-convert.dir=/Applications/QCAD.app/Contents/Resources
dwg-convert.exe=${dwg-convert.dir}/dwg2bmp_alfresco_fallback
dwg-svg-convert.exe=${dwg-convert.dir}/dwg2svg_alfresco_fallback
content.transformer.Dwg2png.extensions.dwg.png.supported=true
content.transformer.Dwg2svg.extensions.dwg.svg.supported=true

#SVG -> PNG
svg-png-convert.dir=/usr/local/bin
svg-png-convert.exe=${svg-png-convert.dir}/rsvg-convert
content.transformer.Svg2png.extensions.svg.png.supported=true

###Frequently Asked Questions How can I improve the quality of the transformations from DWG to PNG?
You can try removing the direct transformation from DWG to PNG and creating DWG -> SVG -> PNG chain.
