This tutorial assumes that you have already installed pdf2cad on your Windows PC and that you can access it from the Start Menu, Desktop or Quick Launch Ribbon. Choose your preferred method and launch pdf2cad.
The General Settings control options that apply to all files. These include choices for how you want text to be converted in your file.
Characters as Strings looks at your file and, based on placement and proximity, will combine individual characters into words and words into editable lines of text.
Convert Characters to Curves will create a graphic match for the text ensuring a perfect match when fonts may be unknown or unavailable of the target system.
Rotate: You can also choose to rotate the file in either direction.
Scale Text: Enlarges or reduces the size of the text in the converted file.
Emulate PDF cropping: Several vector formats such as WMF, CGM, DXF and HPGL do not support cropping. This is the removal of unnecessary portions of the picture such as extraneous fills and other elements. Since PDF does support it, we have developed a proprietary method to simulate cropping which can be applied during conversion. Using this feature, the resulting file will look just like the original.PDF.
Show Font Warning: If the same fonts defined in a PDF file are not installed on your computer, the converted drawing will not display properly. Font mapping is a way to ensure the closest match possible or to compensate for different font naming conventions on different systems.
Ignore paths, text images: Choose if you want to perform the conversion without certain elements.
CAD Format: Choose your format – DWG for AutoCAD, DXF for most engineering and technical programs and HPGL for plotter specific applications.
The Page Settings control options that apply to all files. All of the other option vary depending on whether you choose a vector or bitmap output format.
Crop Picture: Remove Margin: By default, the margins of the PDF file are used. This setting can adjust or remove white space.
Page Size: pdf2cad will automatically figure out the page size. If you want to force a standard or custom page size, select it or enter dimensions.
Convert Range: pdf2cad, by default, will convert all pages of a file. You can set a page range if you only want selected pages.
Page Mapping: By default, a multipage PDF file will be converted into a single file. Other options are Merge, Horizontal and Vertical.
The DWG/DXF options apply specifically to the attributes of the CAD drawing. Here you can adjust scale as well as treatment of layers and composition.
Scaling Factor: CAD formats do not define physical dimensions using absolute measurements from a ruler. Instead it uses units which the user defines. These units are lost when the PDF is created, but the scale, the xy relationship, remains. You can set a scaling factor to apply during the conversion to achieve the size drawing you want or you can set the correct units when you open it in a CAD program. By default, pdf2cad uses 1mm(0,03937 inch) in the PDF = 1 unit in the DXF.
Precision Factor: Sometimes pdf2cad delivers better precision and more accurate coordinates if you change this setting from 10.0 instead of 1.0. If this does not help, please send us the file to diagnose.
Paths as Polylines/Polygons: The proprietary object recognition engine will identify the relationship between paths and, if contiguous, will render them as polylines or polygons.
Layers: By default, all objects are placed on the same layer. They can be separated by color, line width, PDF layers, spot colors as well as a combination of color and line width.
Minimum line width: Defines the minimum line width for each vector object in mm. The default is 0.
Zero line width: Remove 3D effects
Dashed and Dotted lines as segments: Recognizes dashed and dotted lines as lines with attributes. Without this feature on, a dashed line would be converted as a number of small line segments.
Fill option: Sometimes, white fills in a PDF file show up as black fills in a DXF file. If this is a problem, use this option to ignore white fills.
Recognize Circles/Ellipses: The proprietary object recognition engine identifies closed polygons and circular paths and converts them to circles and ellipses.
Recognize Horizontal/Vertical Dashed Lines: Instead of being broken down into a number of smaller line segments, dashed and dotted lines can be treated as singular objects with attributes such as line type.
Error Tolerance: This is a tolerance level set for recognition of CAD objects. If one point on the closed polyline is outside of the specified range, it will remain a polyline.
Kerning Factor: This setting controls the space between letters or characters. Normally, one should not need to worry about kerning but if you do want to change the character spacing you can do it with a kerning factor. Note that a spacing problem may not be a kerning issue – it may be due to a font mismatch and would be best solved with a font mapping.
Compound Objects: The object recognition engine will try to turn as many objects as possible into grouped or compound objects. If you want all graphics to remain as singular objects, turn this off.
Convert Hidden Text Objects: Often, PDF files will contain text that is transparent or hidden under an object. This option will extract all text, including hidden text.
Fir Drawing: This option ensure that the converted drawing will be entirely visible when opened up in a CAD program.
Include AI Prologue file:
Custom Line Styles: Line styles in the PDF can be mapped to custom line styles in the DXF file.
Use True Color:
Simple Mode: By default, pdf2cad will convert one file at a time. To use batch mode to convert multiple files, turn Simple Mode off.
The converted files will be in your file system, usually in the same folder as the original folder. You can now open them in your CAD application. At this point, you can choose New Conversion to perform more operations or Exit the application. If there are any warnings, check the Details button to review them. In almost all cases, these will be warnings about fonts which were in the original PDF file but are not on your PC, meaning that a substitute font will be used. Errors are very rare and if you encounter one, please report it to us along with the file.
This tutorial assumes that you have already installed pdf2cad on your Mac and that you can access it from the Applications Folder, the Dock or the Desktop. Choose your preferred method and launch pdf2cad.
The selected files will be displayed in the preview pane on the left. On the right, are the most often used settings. These defaults should be correct for most conversions. Click OK to continue. If you find that you need to change rotation or fine-tune the process, there is a Preferences button where more settings can be applied. If you do not need to make any adjustments, click OK to run the conversion. The Preferences are covered at the end of the tutorial.
The conversions to be performed will be summarized on screen. Choose where the results will be stored. The default is in the same directory as the original file. Click Convert to proceed.

When you click on Preferences after selecting your files for conversion, you will see a number of options to define the conversion parameters. A description of each of the 4 tabs follows – General, Fonts, DWG/DXF and Advanced.
Emulate PDF cropping: Several vector formats such as WMF, CGM, DXF and HPGL do not support cropping.

Since PDF does support it, we have developed a proprietary method to simulate cropping which can be applied during conversion. Using this feature, the resulting file will look just like the original PDF.
Font Settings: If the characters are converting but not displaying properly, you likely have a font mapping issue. To comply with the licensing regulations of font suppliers, our software can not embed fonts in the vector output formats. Instead, we reference the fonts by their names. If the fonts on the target Mac use the same name, the file will open and display perfectly. If the same fonts are not on the Mac that opens the file, which is much more likely, the text will not display properly. To complicate things, often, one font may go by several different names. Arial Bold, for example, may be referenced as “EHJPKB+Arial-Bold” in the original file. This font may be normal Arial Bold but the target application does not know it unless you tell it. This is known as font mapping. If the font is not mapped correctly, the closest font will be substituted. In this example, “EHJPKB_Arial-Bold” must be mapped as “Arial” with font style “Bold”.
The DXF/DWG options apply specifically to the attributes of the CAD drawing. Here you can adjust scale as well as treatment of layers and composition.
Kerning Factor: This setting controls the space between letters or characters. Normally, one should not need to worry about kerning but if you do want to change the character spacing you can do it with a kerning factor. Note that a character display problem may not be a kerning issue – it may be due to a font mismatch and a font mapping will best solve it.
