How to Fix Distorted or Overlapping Text During CAD PDF Publishing?
Overlapping or distorted text in PDF exports occurs when fonts are converted to geometry, non-standard text width factors are applied, or system variable TEXTFILL is disabled. Resolve by enabling font embedding in PDF driver properties and ensuring standard 1.0 width factors.
Tested on GstarCAD PDF driver and Adobe Acrobat Reader on Windows 11.

Direct Diagnostic Solution & Protocol
Quick Resolution: Overlapping or distorted text in PDF exports occurs when fonts are converted to geometry, non-standard text width factors are applied, or system variable TEXTFILL is disabled. Resolve by enabling font embedding in PDF driver properties and ensuring standard 1.0 width factors.
Step-by-Step Engineering Execution
Step 1: Verify Text Style Width Factors
Type STYLE. Select your active text styles. If 'Width Factor' is set to non-integer values like 0.73, third-party PDF rasterizers miscalculate character kerning, causing glyphs to overlap. Reset to 1.0.
Step 2: Configure Built-in PDF Plotter Properties
Type PLOT → select 'DWG to PDF.pc3' → click 'Properties'. Under 'Device and Document Settings', expand 'Custom Properties'. Ensure 'Capture fonts used in drawing' is checked.
Step 3: Enable Font As Text (Disable Geometry Stroke)
In PDF options, toggle 'Convert text to geometry' OFF. Leaving text as native TrueType fonts keeps text searchable in Adobe Acrobat and prevents letter distortion.
Step 4: Reset TEXTFILL & FILLMODE System Variables
Type TEXTFILL and verify it is set to 1. Ensure FILLMODE is also set to 1. Execute REGENALL before publishing.

Underlying Kernel Mechanics & Automated Prevention Protocol
To permanently prevent recurrence of How to Fix Distorted or Overlapping Text During CAD PDF Publishing? across enterprise project directories, CAD managers must understand how the underlying DWG object database (AcDbDatabase / GcDbDatabase) and graphics display pipeline manage entity handles, symbol tables, and external dependencies:
| Diagnostic Command / Variable | Recommended Production Value | Engineering Function & Impact |
|---|---|---|
| AUDIT / RECOVERALL | Fix Errors = Yes (Y) |
Validates B-tree symbol tables, repairs orphaned dictionary handles, and heals nested Xrefs. |
| -PURGE → Regapps (R) | Verify Each = No (N) |
Strips thousands of unreferenced third-party Registered Application IDs that bloat DWG memory. |
| GRAPHICSCONFIG | Hardware Acceleration = ON | Verifies DirectX 11/12 or OpenGL GPU driver allocation and clears corrupted display cache buffers. |
