Image to Path

Image to Path traces the outlines of an image to create 2D paths. These paths can then be extruded, revolved, or used with any other path operation. This is ideal for converting logos, silhouettes, and simple graphics into 3D objects.

How to Use

  1. Select an image object in your workspace
  2. Click Image to Path in the Image group of the toolbar
  3. Choose the analysis type and adjust the selection range

Parameters

  • Analysis Type - How the image is analyzed for tracing:
    • Transparency - Trace based on transparent vs opaque areas (best for PNGs with transparent backgrounds)
    • Colors - Trace based on color regions
    • Intensity - Trace based on brightness levels (best for most images)
  • Select Range - A histogram control to select which brightness/color values to include in the trace
  • Min Surface Area - Drops small traced loops, measured in the picture’s pixels (default 1; the slider runs 0 to 150). A loop is kept only if its area is at least this number squared, in square pixels: 1 keeps loops of 1 square pixel or more, 10 needs 100 square pixels. Increase it to filter out small specks. When the trace finds only one loop, it is always kept

Tips

  • Clean, high-contrast images with simple shapes work best
  • Use Transparency mode for PNG images with transparent backgrounds
  • Use Intensity mode for photographs and images without transparency
  • After tracing, apply Linear Extrude to give the path height
  • Increase Min Surface Area to remove small unwanted details from the trace
