How to Edit AutoCAD SHX Text in PDF?

Understanding SHX Text in PDF Files

SHX text refers to a type of font used in AutoCAD that can create various shapes and styles. When editing AutoCAD drawings that include SHX text, it becomes essential to consider how this text translates into other formats, such as PDFs. Often, SHX text might not render correctly in PDFs due to font compatibility issues, which raises the question of how to effectively edit it when exporting to PDF.

Steps to Edit SHX Text in PDF

Step 1: Identify the SHX Text in Your AutoCAD Drawing

Begin by opening your AutoCAD 2025 project. Locate the elements that include SHX text within your drawing. Make a note of which sections require editing or adjustments.

Step 2: Replace SHX Fonts with TrueType Fonts

To ensure that the text appears correctly in PDFs, convert any SHX fonts to TrueType fonts. This can be done easily within AutoCAD:
1. Select the text entities that use SHX fonts.
2. Right-click and choose “Properties.”
3. In the Properties palette, under the “Text” category, select a TrueType font from the dropdown list.
4. Apply changes to all relevant text elements.

Step 3: Export the Drawing as PDF

After you have replaced the fonts, the next step is to export your drawing as a PDF:
1. Go to the Application menu in AutoCAD and select “Print.”
2. Choose “DWG to PDF.pc3” from the printer list.
3. Click on “PDF Options” and make adjustments such as unchecking “Include layer information” if necessary.
4. Click “OK,” then set your desired output file location and name for the PDF.
5. Hit “OK” to initiate the PDF creation process.

Step 4: Verify the PDF Output

Once the PDF is generated, open the file using a PDF viewer (such as Adobe Acrobat). Check to ensure that all text appears correctly and matches your expectations.

Removing SHX Text from a PDF

If you have a PDF that contains SHX text and you want to remove it, follow these steps:

Step 1: Use Comment and Form Settings

1. Open the PDF in Adobe Acrobat.
2. Navigate to the print settings by selecting “Print.”
3. In the “Comments and Forms” section, choose “Document Only.” This will ensure that SHX text does not appear as a comment overlay in the final output.

Step 2: Flatten the PDF

For a more permanent solution:
1. Make a backup of your PDF file.
2. Go to “Advanced” and select “Print Production” followed by “Flattener Preview.”
3. Configure settings such as “Convert All Text to Outlines” to avoid rendering issues.
4. Click “Apply” to finalize the changes.

Converting PDF Back to an Editable Format

If you need to edit a PDF that originally contained SHX text, you can follow these steps to convert it back into an editable AutoCAD format:

Step 1: Import PDF into AutoCAD

1. Open AutoCAD 2025 and create a new drawing or open an existing one.
2. Navigate to the Application menu, then select “Import” and choose “PDF.”
3. Locate the PDF file you wish to edit and click “Open.”

Step 2: Edit the Imported Content

Once the PDF is imported, you can use AutoCAD tools to revise the content. Ensure to replace any remaining SHX text with TrueType fonts to maintain compatibility for future exports.

Frequently Asked Questions

What formats are suitable for inputting fonts into AutoCAD?

TrueType fonts and SHX files are the most common formats allowed in AutoCAD. TrueType fonts typically have better compatibility when exporting to PDF.

Can external tools help convert PDF to DWG for editing?

Yes, there are various tools available, such as AutoDWG PDF to DWG Converter and Any PDF to DWG Converter, that can assist in converting PDFs into an editable DWG format.

What should I do if an SHX file is missing in a drawing?

If an SHX file cannot be found, locate the elements in the drawing that reference that file. You may need to replace those elements or remove them entirely to eliminate the references to the missing SHX file.
