Curved lines are often required to visualize flow directions, such as the movement of population and traffics. This tool is used to convert straight lines into curved arcs to get a better visualization effects during mapping such scenarios.
Convert straight lines (only has start and end vertex) into second order Bezier curves.
Input straight line feature class, i.e. C:\line.shp
Output Bezier feature class, i.e. C:\Flowline.gdb\line2bezier
Parameters：
