How to Convert AutoCAD (DWG) to PDF (Complete guide)

Converting a DWG to PDF in AutoCAD is standard when you need to share drawings, print plans, or submit documents for review. The method you choose directly affects scale accuracy, lineweights, file size, and readability.

This guide covers the methods used in AutoCAD 2027, with practical settings and fixes used in real production environments.

Quick Comparison of Methods

Method 1 – Plot Command (Full Control)

The PLOT command is the reference method for exporting a DWG file to PDF with full control over scale and output quality.

Steps:

• Open your drawing
• Press Ctrl + P (or Cmd + P on Mac) or type PLOT
• In Printer/Plotter, select:
  • AutoCAD PDF (General Documentation) – standard use
  • AutoCAD PDF (High Quality Print) – printing / submissions
  • AutoCAD PDF (Smallest File) – lightweight output
• Set Paper Size
• Define Plot Area:
  • Display
  • Extents
  • Window (manual selection)
• Set Plot Scale (typically 1:1 in Layout)
• Enable Center the plot if needed
• Click OK and save

Important:

• Prefer AutoCAD PDF drivers over DWG to PDF.pc3 (legacy). The newer drivers handle TrueType fonts, lineweights, and hyperlinks more reliably.

Best practice:

• Always plot from Layout tabs, not Model Space
• Use CTB files correctly (e.g., monochrome.ctb)
• Ensure lineweights are enabled

Method 2 – Export Command (Fast Output)

Use this when speed matters more than fine control.

Options:

• Type EXPORTPDF directly (recommended)
• Or use menu:
  • Windows: Application button → Export → PDF
  • Mac: File → Export → PDF

Behavior:

• Uses the current page setup
• Minimal configuration

Use case:

• Quick validation
• Sharing drafts
• No need to adjust CTB or lineweights

Method 3 – Batch Conversion with Publish

For multi-sheet projects, PUBLISH is the standard workflow.

Steps:

• Type PUBLISH
• In Publish to, select PDF
• Review sheet list
• Click Publish Options:
  • Multi-sheet file → one PDF
  • Single-sheet files → multiple PDFs
• Click Publish

Use case:

• Permit sets
• BIM deliverables
• Multi-discipline coordination

Batch Plot Without AutoCAD (DWG TrueView)

If AutoCAD is not installed:

Autodesk DWG TrueView

• Free viewer from Autodesk
• Includes full plotting engine
• Supports Batch Plot (Publish equivalent)

Workflow:

• Open multiple drawings
• Use Batch Plot
• Output to PDF

Use case:

• Teams without licenses
• External collaborators

Method 4 – Cloud and Mobile Workflows (AutoCAD 2027)

AutoCAD now integrates directly with cloud workflows.

Save and Export to Cloud

• Use SAVETOWEBANDMOBILE
• Sync drawings to Autodesk Docs / cloud storage
• Generate PDFs from web or mobile

Use case:

• Field coordination
• Remote review
• BIM collaboration

Recommended Settings for High-Quality PDF

These settings avoid most production issues.

Plot Style (CTB):

• monochrome.ctb → black and white
• acad.ctb → color output

Lineweights:

• Enable Plot with lineweights
• Verify thickness mapping in CTB

Driver:

• Use AutoCAD PDF (High Quality Print) for submissions

Scale:

• Plot from Layout at 1:1

Transparency:

• Disable unless required

Fonts: SHX vs TrueType (Important)

SHX Fonts

• Can generate boxed or comment-like text in PDF
• Controlled by:
  • System variable PDFSHX
  • OR PDF driver options (newer versions)

TrueType Fonts (TTF)

• Examples: Arial, Calibri
• Remain clean, searchable, and stable
• No need to adjust PDFSHX

Recommendation:

• Use TrueType fonts when possible for deliverables

PDFSHX and Text Behavior (Updated for 2027)

To avoid SHX text issues:

• Set PDFSHX = 0 → converts text to geometry
• OR open PDF Options in Plot dialog:
  • Disable “Convert SHX text to comments”

Note:

• In AutoCAD 2025–2027, PDF driver settings can override PDFSHX
• Always verify in PDF Options dialog

Common Problems and Fixes (Troubleshooting)

PDF is blurry

• Use High Quality Print driver
• Increase DPI
• Avoid raster-heavy drawings

Wrong scale

• Plot from Layout
• Set scale to 1:1
• Disable Fit to paper

Lineweights not visible

• Enable Plot lineweights
• Check CTB file
• Verify object lineweight settings

Colors not correct

• Check CTB/STB configuration
• Confirm plot style assignment

File too large

• Use General Documentation driver
• Disable transparency
• Reduce embedded images

Text appears boxed or strange

• Set PDFSHX = 0
• Or disable SHX comments in PDF Options

Alternative Quick Method (Reference)

• Press Ctrl + P
• Select AutoCAD PDF driver
• Set Plot Area = Window if needed
• Enable Center the plot
• Use Fit to paper only if scale is not critical
• Save PDF

Other options:

• EXPORTPDF for quick output
• DWG TrueView for free conversion
• PUBLISH for batch output

FAQ – DWG to PDF in AutoCAD

How do I convert DWG to PDF in AutoCAD 2027?

Use the PLOT command and select an AutoCAD PDF driver such as General Documentation.

What is the best method for multiple layouts?

Use PUBLISH with Multi-sheet PDF enabled.

Can I convert DWG to PDF without AutoCAD?

Yes, using Autodesk DWG TrueView, including batch plotting.

Why is my PDF not showing correct lineweights?

Check CTB file, enable Plot lineweights, and verify object settings.

Why is my AutoCAD PDF blurry?

You are likely using a low-quality driver. Switch to High Quality Print.

How do I maintain correct scale?

Plot from Layout at 1:1 scale. Avoid “Fit to paper.”

What is PDFSHX and should I use it?

PDFSHX controls how SHX text is exported. Set it to 0 to avoid comment boxes, but check PDF Options since newer drivers can override it.

Are TrueType fonts better than SHX for PDF?

Yes. TrueType fonts remain searchable and clean without extra configuration.

Can I export directly to cloud or mobile?

Yes. Use SAVETOWEBANDMOBILE and generate PDFs from Autodesk cloud tools.
