Creating Rough Curves From an Image

You can extract rough curves from an imported image.

Before you begin: Import an image. See Importing Images as a Support.

  1. From the Images section of the action bar, tap Sketch Extraction .
    A set of rough curves representing the image is created.

    Important: In case of an SVG image, a panel appears with the number of imported objects and created layers. SVG objects are converted and imported into NTS objects, as shown in the mapping table below:
    SVG Objects NTS Objects
    Line Primitive line
    Rectangle Four primitive lines
    Rectangle (rounded) Two arcs and two primitives lines
    Ellipse Primitive ellipse
    Circle Primitive circle
    Polygon Primitive lines
    Arc Arc
    Text Image support
    Brush paint Image support (created in a specific layer)
    Image Image support
    Layer Geometrical set
    Pencil Curve
  2. To modify the resolution of the image, press the pen button bound to the right-click of the pointer and tap the image edge.
    The Image Resolution panel appears and displays the possible available resolutions.
  3. From the standard area of the action bar, tap Transform.
    Tip: You can also double-tap the image to launch the Transform command.
  4. Transform the selected curves by performing either of the following operations:
    • Resize the curves by dragging the corners or the edges of the handle's plane.
    • Translate the curves along the directions of the handle.
    • Translate the curves along the normal of the handle.
    • Rotate the curves using the center point of the handle.
    Transformation operations are also available by double-tapping the image, and through Modify.
  5. Optional: Copy, cut, paste, or delete the image as appropriate.

You can now use this image as a drawing support for sketching or tracing.
