Increasing the number of segments

You may wish to add segments to the line to draw it more sophistically between the process steps.

You can easily add a new segment by dragging one of the ending segments of a line:

Each time you drag the end segment beyond the edge of a step icon a new segment is added at the end of the line.

You can also create three new segments in the middle of an existing one. Just press <Shift> key while dragging the middle point of the segment.
