How We 3D-Scan and Convert Automotive Surfaces Into Vector Templates

At AutoVectors.com we create true-scale vector patterns for PPF, vinyl wrap and motorsport applications. Below is a look at how our workflow evolved – from early transfer-paper templates on the car to today’s 3D scanning and digital surface flattening pipeline.

Early Stage – Transfer Paper Method

Before moving into 3D scanning workflows, our earliest templates were created using transfer paper film applied directly to the vehicle surface. The film was wrapped, all key lines were traced by hand, and then the pattern was removed and digitized. These are a few examples from that first-generation process.

Advanced 3D Scanning & Digital Surface Flattening

Today most complex panels are captured with a structured-light 3D scanner, then converted into true-scale 2D vector templates using ExactFlat and our own CorelDRAW / Illustrator workflow.

Earlier we used a more complex 3D pipeline for some projects:

  • 3D scan of the part or full vehicle panel;
  • Quicksurface to rebuild clean 3D geometry on top of the scan;
  • SolidWorks surface flattening to create precise 2D patches;
  • Export to AI/CDR and final vector clean-up.

This workflow delivers very high quality, but rebuilding geometry in Quicksurface and then flattening it in SolidWorks takes a lot of time. For day-to-day pre-cut pattern work we needed something faster and more direct, so we moved to a streamlined ExactFlat-based route:

  • 3D scan with a structured-light scanner;
  • ExactFlat digital flattening directly on the scanned mesh to generate accurate 2D pieces;
  • Export to AI/CDR and optimize the vectors in CorelDRAW / Illustrator (smoothing fillets, mounting holes, alignment marks);
  • Final vector polishing and packaging into pre-cut patterns ready for plotter cutting.

In short, the modern process for complex panels usually looks like this: 3D scan → ExactFlat digital flattening → AI/CDR vector optimization → final pre-cut template. Below you can see a few snapshots from this 3D pipeline.

Why This Matters for Installers

Combining both approaches — transfer paper and 3D scanning — lets us choose the best method for each panel. Simple parts can still be traced quickly on paper, while complex bumpers, lips and motorsport parts benefit from a full 3D workflow.

The result is a library of true-scale vector patterns that are engineered for professional plotter cutting, faster installation and predictable fitment on real cars.
