Working with PDFs created from AutoCAD drawings in Adobe Acrobat can sometimes present challenges, particularly concerning SHX text. These AutoCAD-specific fonts, while perfectly functional within the CAD environment, often cause issues when converted to PDF format and opened in Adobe Acrobat. This can manifest as unexpected pop-up comments, slow performance, and difficulties in text selection and manipulation, leading to a frustrating user experience. Addressing these issues is crucial for maintaining the usability and accessibility of your PDF documents. BreezePDF offers a streamlined and efficient solution to tackle these problems.

One frequent annoyance is the appearance of pop-up comments seemingly attached to the SHX text, which can clutter the document and interrupt the reading flow. Furthermore, PDFs containing numerous SHX text objects may exhibit sluggish performance, making it difficult to navigate and work with the document efficiently. The individual geometric representation of SHX fonts can also hinder the selection and editing of text within the PDF. Luckily, there are ways to improve this!
Understanding SHX Fonts and AutoCAD PDFs
SHX fonts are a specific type of font used primarily within AutoCAD. Unlike standard TrueType fonts, SHX fonts are unique to the AutoCAD environment and are commonly used in CAD drawings for their specific visual characteristics and compatibility within the software. These fonts are often used to represent technical information, annotations, and other text elements within CAD designs, which are critical for communicating design intent and specifications. It's important to understand these fonts to know how to work with them.
The reason SHX text becomes problematic in PDFs is due to how AutoCAD handles the conversion process. When creating a PDF from an AutoCAD drawing, the software converts SHX fonts into individual geometric objects rather than embedding them as standard text. Adobe Acrobat may then interpret these geometric objects as comments, leading to the pop-up comment issue. Although the text remains searchable, this conversion process significantly increases the file size and slows down performance, impacting the overall usability of the PDF. If you are working with AutoCAD to PDFS, it's important to understand how to manage this.
Methods to Remove or Manage AutoCAD SHX Text in Adobe Acrobat
While Adobe Acrobat offers some limited options for managing SHX text, these methods often fall short of providing a complete solution. Hiding SHX Text Comments via the comments panel (View > Tools > Comment > Open, then filter to hide) is one such approach. However, this only conceals the visual clutter without addressing the underlying performance issues caused by the numerous geometric objects. Hiding comments can improve readability but does not reduce file size or improve document responsiveness. Other methods are needed!
Changing Adobe Acrobat preferences, such as disabling "Enable text indicators and tooltips" in Edit > Preferences > Commenting, offers another limited fix. While these changes can affect the pop-up open behavior, they don't truly remove the SHX text or resolve the performance problems. Another option is flattening the PDF which merges all layers into a single layer and effectively removes the editable text and other interactive elements. This can reduce the file size and prevent further issues with SHX fonts, but it also makes the document non-editable.
Preventing SHX Text Issues at the Source (AutoCAD)
The most effective way to avoid SHX text problems in PDFs is to prevent them from occurring in the first place by making changes in AutoCAD. Using TrueType Fonts (TTF) instead of SHX is a primary preventative measure. TTF fonts embed properly in PDFs, eliminating the conversion to geometric objects and the associated issues. To change fonts in AutoCAD, use the STYLE command to define text styles that use TTF fonts. This ensures that text is properly embedded when creating PDFs. Preventing the problem is easier than fixing it.
Another crucial setting in AutoCAD is the PDFSHX system variable. By setting the PDFSHX/EPDFSHX variable to 0, you can eliminate SHX comments during PDF creation. Note, however, that setting this variable to 0 can impact PDF searchability, as the text may not be recognized as selectable text. Also, unchecking “Include Layer Information” (or similar options) in AutoCAD PDF export settings can also help prevent SHX text issues by simplifying the PDF structure and reducing the likelihood of conversion problems. Searchability is an important factor to keep in mind.
Using Third-Party PDF Editors
While Adobe Acrobat is the industry standard, several third-party PDF editors offer alternative solutions for handling SHX text. Foxit Reader is one such alternative, with some users reporting better handling of SHX fonts and fewer issues with pop-up comments. Bluebeam Revu is another option, particularly well-suited for engineering and drafting PDFs. Each software handles the fonts in a different way.
Consequences of SHX Text and Why Removal is Important
The presence of SHX text in PDFs can lead to several undesirable consequences. Difficulty Selecting & Editing Text is a primary issue, as the geometric representation of SHX fonts makes it challenging to select and modify text within the PDF. Large PDF File Sizes are another common problem, as the conversion to geometric objects significantly increases the file size compared to embedded text. The searchability is also decreased because the document is not interpreted as text.
Performance Issues in Adobe Acrobat are also common, with PDFs containing numerous SHX text objects often exhibiting sluggish performance, making it difficult to navigate and work with the document efficiently. These challenges highlight the importance of addressing SHX text issues to ensure PDF usability and accessibility. Luckily, there is a great solution for this.
