Round Corner Tool

What it Does​

Converts sharp corner points into smooth, curved transitions by replacing the angular junction with a precisely controlled arc. The tool maintains mathematical tangency with the original lines, ensuring seamless integration while providing exact control over the curvature through independent X and Y radius settings.

tip

The Lock checkbox keeps X and Y radius values synchronized for perfect circular arcs. Unlock it to create elliptical corners with different horizontal and vertical curvatures.

How to Use​

  1. Activate the tool by clicking the Round Corner icon
  2. Click to select the corner point where you want to create a rounded transition
  3. Adjust the radius using sliders or enter specific values in the X Radius and Y Radius boxes
  4. By default, the Lock checkbox is selected to maintain equal X and Y radius values
  5. Deselect the Lock checkbox to enter different X and Y radius values for elliptical corners
  6. Click Preview to see how the rounded corner will appear
  7. If the corner arc is drawn on the wrong side, use Other Side to correct the orientation
  8. Click Save to apply the rounded corner or Cancel to abort
warning

The radius values must be smaller than the distance from the corner point to adjacent points on the connecting lines to avoid geometric conflicts.
