If you’ve ever printed a drawing only to find that patterned line types don’t look the way they did on your screen, you’re not alone. In previous versions, patterned lines—like dashed or slash-style lines—were dependent on Windows and PDF printer drivers. And that often meant inconsistent results.
In TPC 26, that problem is gone.
TPC Now Draws Pattern Lines Itself
Beginning with TPC 26, TPC draws pattern line types directly, instead of relying on your Windows or PDF printer driver.
This change ensures that patterned line types—such as /Dash and other predefined patterns—print exactly as they appear on your monitor. What you see on screen is now what you get in the PDF.
No driver quirks. No printer-specific surprises. No last-minute fixes.
Why This Is a Big Deal
This is more than a cosmetic improvement—it’s a reliability upgrade.
- Consistent PDFs across systems
Whether you’re exporting a PDF for internal review, client delivery, or record submittals, patterned lines now appear the same on every machine. - Fewer print test runs
No more printing multiple versions just to check line patterns. - More confidence in final deliverables
The drawing you approve on screen is the drawing you send out.
For teams that rely heavily on PDFs as final deliverables, this change alone can save time and frustration on every project.
New Predefined Line Type Examples
To make it easy to see and use the available pattern lines, TPC 2026 includes a new Predefined Linetypes.trv survey in the Sample Surveys.
Inside, you’ll find:
- Drawings that showcase all predefined line types
- Clear examples of how each pattern appears on screen and in output
- A quick reference when choosing line styles for your own projects
It’s a simple addition that makes adopting consistent line styles easier than ever.
A Compelling Reason to Update
PDF Pattern Lines are a fundamental improvement to how TPC produces final output. By taking control of how patterned line types are drawn, TPC 26 removes a long-standing source of inconsistency and puts reliability back where it belongs—in the software itself.
If clean, predictable PDFs matter to your workflow, this feature alone makes TPC 26 a must-have upgrade.
