Answer :

The orthographic views can be completed by using the given cutting plane line to show the sectional view of the object.

Orthographic views are two-dimensional representations of a three-dimensional object, showing multiple views from different directions. The sectional view is used to display the internal structure of the object, providing additional information and clarity.

In this case, the section AA is used as a cutting plane line to reveal the internal features of the object. By slicing the object along this plane, a sectional view is created, showing the hidden details that cannot be seen in regular orthographic views.

The sectional view is essential in engineering, architecture, and design as it allows for a better understanding of complex structures, assemblies, and components. It helps in visualizing the object's internal arrangement, identifying potential issues, and ensuring proper assembly and fit.

By incorporating the section AA into the orthographic views, the drawing becomes more comprehensive, providing a complete representation of the object. This ensures that all necessary information about the object's design, dimensions, and internal features is communicated effectively to the viewer.

In conclusion, the given cutting plane line (section AA) is used to complete the orthographic views and provide a sectional view of the object, offering a more detailed representation for better understanding and analysis.
