Abstract
A tool is provided via a user interface for a digital media application that supports digital illustrations. The tool combines operations to create different types of segments for a drawing shape and covert between types of segments. The tool is configured to analyze the drawing to recognize segments that are straight, arc, or curved portions of the drawing path. For segments recognized as curved, the segments are represented as Bezier curve segments. For segments recognized as straight, the segments are represented as line segments. Additionally, line segments are associated with handle elements operable to convert the line segments to regular arc segments. Responsive to manipulation of a handle element for a particular line segment, the tool computes a corresponding regular arc and converts the line segment into a regular arc segment.
