Hatches Missing from AutoCAD PDF: Causes and Fixes
If hatches disappear from an AutoCAD PDF, check whether they are already missing in Plot Preview, whether the hatch layer is plottable, whether screening or transparency makes them too faint, and whether dense patterns are being rendered as expected.
Start here — what you are going to do
Your goal: Determine the first stage where the hatch disappears or becomes too faint, then correct the setting responsible.
Where to start: Use one affected Layout and, if possible, one known-good PDF from the same project.
Beginner rule: Always compare AutoCAD Preview with the saved PDF. If Preview is correct, avoid changing the drawing for a viewer or printer problem.
Step by step — follow this in AutoCAD
Step 1 — Check Plot Preview
Where: AutoCAD > Ctrl+P > Preview.
Do this: Look specifically for missing hatch areas.
Check: You know whether the problem already exists before PDF creation.
Step 2 — Check the Page Setup
Where: PAGESETUP > Modify.
Do this: Confirm PDF PC3, paper, Plot Area, 1:1 Layout scale and CTB/STB.
Check: The common output controls are known.
Step 3 — Check hatch in Preview
Where: Ctrl+P > Preview.
Do this: Zoom to hatch region.
Check: You know whether loss occurs before PDF creation.
Step 4 — Check hatch layer
Where: Layer Properties.
Do this: Confirm visible, thawed and Plot enabled.
Check: Layer is allowed to output.
Step 5 — Check color and plot style
Where: Properties + CTB/STB.
Do this: Look for screening, white color or faint mapping.
Check: Hatch should be visible.
Step 6 — Check transparency
Where: Hatch/layer Properties + Page Setup.
Do this: If transparent, confirm Plot Transparency.
Check: Transparency is deliberate.
Beginner example
If the hatch is visible in Plot Preview but missing or much lighter in the PDF, check PDF rendering and quality. If Preview is already wrong, check the hatch layer, screening, transparency and plot-style mapping.
Understand what AutoCAD is doing
The first bad stage matters
Model/Layout → Preview → PDF → paper. The first stage that becomes wrong tells you where to focus.
A known-good reference saves time
Compare Page Setup, PDF preset and final file rather than guessing.
One symptom can have several causes
The steps isolate the responsible stage before you change anything.

Common problems and what to check first
| What you see | What may be causing it | Check this first |
|---|---|---|
| Hatch absent in Preview | Drawing/layer/plot-style issue | Fix AutoCAD source. |
| Hatch extremely faint | Screening/transparency too high | Adjust approved output property. |
| Dense hatch looks odd | Pattern/rendering detail | Test PDF quality and scale. |
| Physical paper differs | Printer rendering | Compare verified PDF. |
When you need a more repeatable workflow
Keep representative reference PDFs for scale, fonts, lineweights, images and hatches. When a PDF preset, AutoCAD version or device environment changes, compare against those references before project-wide changes.

Frequently asked questions
Should I increase DPI first?
Only after confirming hatch is present in Preview and output properties are correct.
Can CTB screening hide hatches?
Yes.
Can transparency affect hatch output?
Yes.
