What Is the Smooth Tool in CorelDRAW?

The Smooth Tool in CorelDRAW is a vector editing feature designed to eliminate jagged edges and reduce redundant nodes along vector paths. This article explains what the tool does, how to configure its settings, its key benefits in vector illustration, and the most common workflows where it proves essential for achieving clean, professional artwork.

Understanding the Smooth Tool

Located within the Shape tool flyout menu on the CorelDRAW toolbox, the Smooth Tool operates like an interactive brush. Instead of requiring you to select and delete individual nodes manually, the tool lets you drag across an existing path to automatically average out sharp transitions and simplify complex vector geometries. As you apply the tool, CorelDRAW recalculates the Bézier curves, producing a fluid, organic line while preserving the overall silhouette of the object.

Key Tool Settings and Controls

When the Smooth Tool is active, the Property Bar offers several parameters to customize its behavior:

  • Nib Size: Determines the diameter of the circular brush. A larger nib affects broader sections of the curve simultaneously, while a smaller nib enables precise, localized adjustments.
  • Rate: Controls the speed and intensity of the smoothing action. Higher values smooth the path aggressively with fewer passes, whereas lower values allow for subtle, gradual adjustments.
  • Pen Pressure Support: If you are using a graphics tablet, you can toggle pressure sensitivity to control the nib size or smoothing rate dynamically based on how hard you press the stylus.

How to Use the Smooth Tool

  1. Select the vector object you want to modify using the Pick Tool.
  2. Click and hold the Shape Tool in the toolbox, then select the Smooth Tool from the flyout menu.
  3. Adjust the Nib Size and Rate on the Property Bar to match the scale of your design.
  4. Click and drag the cursor along the path or outline of the object. Repeated strokes over the same area will progressively reduce the node count and soften the curves.

Common Practical Applications

The Smooth Tool is especially useful in scenarios where vector data contains an excess of structural points:

  • Cleaning Up Auto-Traced Artwork: Converting bitmap images to vectors via CorelDRAW's PowerTRACE often generates hundreds of unnecessary nodes and jittery edges. Running the Smooth Tool across these paths quickly normalizes the outlines.
  • Refining Freehand Line Art: Digital sketches drawn with the Freehand or Art Media tools frequently exhibit slight hand tremors. The Smooth Tool corrects these imperfections without flattening the artwork entirely.
  • Optimizing Files for Production: Vector paths intended for CNC routing, vinyl cutting, or laser engraving require minimal node counts to ensure machine tools move smoothly. Smoothing paths reduces cut times and prevents physical cutting errors caused by dense node clusters.
