To draw multiple span segments

Choose the Span Segment Polyline tool ().
Click at the first span segment start point.
Click at the first span segment end point.
Click at the second span segment end point.
Continue to click segment end points until all related segments are drawn.
Right click and select enter to close the operation.

Note: Start and end points are normally supports. There are, however, exceptions, such as a design strip used for a pour strip to discriminate between PT and RC areas, or used for a span with user-defined reinforcement in discrete locations.
