The document summarizes the Interactive Contour Tool in CorelDraw. It can add contour lines to an object using its outline. Users can set the offset, color, and direction of the contours as interior, exterior, or centered. Similar to the Blend Tool, it creates a series of evenly spaced copies of the outline inside or outside to produce a smooth effect when many contours are closely spaced. The steps to add contour effects are to draw an object, select the Contour Tool, and adjust properties like position, number of steps, offset distance, corner style, color direction, and colors in the tool bar.
