title: Java library to programmatically convert AutoCAD .dwg files to PDF or image?
body: <p>Is there a Java library (free and open source) that converts .dwg files directly to PDFs or images file? The .dwg uses recent normes of CAD (R14, R13, R12, and 2013).</p>
  
  <p>I know that there are a few in .NET and C++... The ones in Java are mostly proprietary and expensive (example: Teigha for Java).</p>
  
  <p>The free ones in Java such as Kabeja passes through an intermediary format, .dxf, which is a very huge file...</p>
