receiving, by a processing device, a first path and a second path displayed in a user interface;

determining, by the processing device, an end section of the first path and a corresponding end section of the second path;

identifying, by the processing device, a first primitive based on a curvature of the end section of the first path and a second primitive based on a curvature of the corresponding end section of the second path; and

generating, by the processing device, a connection path for display relative to the first path and the second path in the user interface by converting the first primitive and the second primitive into a Bezier curve that is a continuous path, the Bezier curve replacing the end section of the first path and the end section of the second path and connecting the first path to the second path.
