DWG ("drawing") is a binary file format used for storing two and three dimensional design data and metadata. It is the native format for several CAD packages including AutoCAD, IntelliCAD (and its variants) and Caddie. In addition, DWG is supported non-natively by many other CAD applications. The .bak (drawing backup), .dws (drawing standards), .dwt (drawing template) and .sv$ (temporary automatic save) files are also DWG files. Like DWG, DXF is also used in CAD applications. If you know how to convert the DWG file to PDF one then you can process both.
I recommend a software to you. AutoCAD DWG and DXF To PDF Converter v2.2 It allows you convert DWG to PDF, DXF to PDF directly without need of AutoCAD, it converts DWG and DXF files into vector PDF files, quick and easily.
