The video demonstrates the process of creating the first routing curve by selecting the feature routing curve and adding points using the manipulator. It explains the reference coordinate system, editing point positions, and controlling the manipulator in rotations and translations. The video also covers the curve reference section, overriding the reference coordinate system for specific points, and the parametric associative updates for the routing curve. Additionally, it introduces alternative methods for creating routing curves, such as using edges or a CSV file import, and discusses the ability to switch between interpolated spline and polyline for the routing curve. The use of bend radius for polyline segments and the option to keep points, creating additional point objects, are also explained.
