You can now transform single segment polylines into straight or curved beams using the Beam, Polyline command.
The command was modified so that you can now transform one-line segments into beams and polylines made of one-arc segments into curved beams. You can also use the Beam, Polyline command to transform lines into straight beams and arcs into curved beams. The command line prompt was also modified to better reflect the new behavior to: "Please specify start point or select objects (line, arc, polyline) [Object]:".
