By converting from PDF to DWG, you can easily increase the size of a drawing or picture, and then edit and copy individual elements.

There are two types of PDF files: raster and vector. A raster PDF is an image made of thousands or millions of pinpoints of color information, called pixels or dots.  A vector PDF, on the other hand, use math to draw shapes using points, lines and curves.  A vector PDF can be uploaded into a CAD program, but a raster PDF needs to be redrawn by tracing the lines.

There are two types of raster PDF to DWG conversion for engineering and architectural drawings: manual vectorization and auto-vectorization. Manual vectorization requires that you make the PDF a background image in your AutoCAD file and then you can manually trace over it. Alternatively, you can use one of many auto-vectorization tools in the market.

Manual vectorization has some advantages. Such conversions are fully editable, multi-layer and are 100% dimensionally accurate (i.e. the length of the lines always match what is written on the drawings).

Auto-vectorization’s main advantage is cost and speed, but there is a sacrifice in terms of quality and features. Layering, for example, is not an option. Most auto-vectorization tools are able to convert both the raster and vector elements in a PDF file to DWG format, ensuring that you are able to edit the entire file. is a leading provider of PDF to DWG conversion services. We use can follow either a manual process or auto-vectorization software to convert your PDF drawings into AutoCAD format.

Most of our clients prefer that we use our manual vectorization process becuase old paper drawings tend to lose their clarity and become distorted over time. Auto-vectorization software accepts all the distortions, but our CAD experts can recreate the drawings manually according to the dimensions mentioned on the drawing, giving you error-free DWG files.

Our manual process can provide you with the following:

  • AIA layering standards or your own layering standards.
  • As many layers as you require.
  • Separate layers for dimensions, text, body, hidden lines, and center-lines, etc.
  • Text that is recognizable as text.

Regardless of the process (manual vs. auto-vectorization) our final output  will be in DWG format because we create the drawing as a new, fully editable file.
