If you use Google to look for PDF to AutoCAD conversion there are to many and I test some of them but yet I am not satisfied with it.

This is a simple tutorial for the beginners and are new to AutoCAD, on how to convert PDF files to AutoCAD files, as long as the drawings are vector graphics and not raster graphics.

First of all we must know what is a vector , raster graphics and PDF.

From http://en.wikipedia.org and I quote:

Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics.
Vector graphics formats are complementary to raster graphics, which is the representation of images as an array of pixels, as it is typically used for the representation of photographic images.


An autocad file, corel draw file, an adobe illustrator file are a vector graphics while a picture is a raster file, such as jpeg, gif, bitmap, tiff and etc.

Now those vector graphics with corresponding file extension can be edited directed with the associated programs or applications from where it were made.

Last what is a PDF?

From http://en.wikipedia.org and I quote:

Portable Document Format (PDF) is an open standard for document exchange. The file format created by Adobe Systems in 1993 is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system.[2] Each PDF file encapsulates a complete description of a fixed-layout 2D document that includes the text, fonts, images, and 2D vector graphics which compose the documents. Lately, 3D drawings can be embedded in PDF documents with Acrobat 3D using U3D or PRC and various other data formats.


The purpose of a PDF file is for display and archive. It is intended for viewing and not for editing. And so when you open a PDF using an adobe reader, the document you open cannot be edited, since the sole purpose is for viewing only.

Now some PDF files were made from autocad or from other vector applications such as corel draw and illustrator. These files are fixed in PDF, and no way for editing.

However, there are times that we need to edit the PDF vector files or revise the drawing from that file.

Here is how:

Since PDF was created by Adobe Systems, so I think this can be open in any adobe products such adobe photoshop, adobe illustrator.

The first thing you to do is import the file to Adobe Illustrator. If the PDF has many pages it will open one at a time.

After opening the files to Illustrator, export it to AutoCAD DXF file. Since DXF file is a native autocad file this can be opened to Autocad .

That's all.
