Trace the field sketch cross-section into a precise vector on an 11x17 artboard using the pen tool, label ground, cut, fill, and key elevations, simplify anchor points for smooth curves, and save as PDF for the engineer to review tomorrow.

Before sending to the engineer, make the cross-section calculation-ready — snap key elevation points to a consistent baseline, annotate dimensions and slope ratios, simplify heavy anchor paths while preserving curvature at grade breaks, and include a separate layer with the original sketch so the engineer can verify assumptions quickly.

The tool
Image Trace

Image Trace converts raster images like JPEGs, PNGs, and PSDs into editable vector artwork.

  1. 1

    Create a new Illustrator document by choosing File > New.

  2. 2

    Select File > Place, choose your raster image, and place it on the canvas.

    NoteImage Trace will be grayed out if the placed image is already a vector.

  3. 3

    With the image selected, open the Image Trace panel via Window > Image Trace.

    NoteAlternatively, select a preset from the Control panel.

  4. 4

    Check the Preview box in the Image Trace panel to see real-time changes.

  5. 5

    Select a mode from the Mode dropdown menu that best suits your design.

  6. 6

    Adjust the Colors, Grays, or Threshold slider as needed.

  7. 7

    Select Manage Presets to create, save, or manage custom presets.

  8. 8

    Press and hold next to View to compare the traced image with the source image.

  9. 9

    Click the Expand button in the Control panel or Object > Image Trace > Expand.

    Best practiceAfter expanding, use the Direct Selection Tool (white arrow) to fix awkward curves or jagged lines.

  10. 10

    Ungroup the traced image by selecting Object > Ungroup to edit individual vector paths.

For best results, always start with a high-quality raster image before using Image Trace.

Image Trace functionality is not directly exposed through Illustrator's scripting API for automated vectorization.

Questions people ask

honest answers

Because you rarely think 'I want the redaction tool'. You think 'I have to share this without leaking the client's details'. Start from the need, and the feature finds you.

Real. Every job here was drawn from what people in real roles were actually seen doing in Illustrator — not a feature checklist.

No. Each page gives you a ready prompt you can paste into an AI assistant, plus the plain steps to do it yourself. Start with either — the goal is the finished job, not the tool.
