A sketch is included to show interior designs using a technique called sectioning.
Step-by-step explanation:
In order to identify interior designs, an engineer includes a sketch to show interior designs using a technique called sectioning.
Sectioning is a technique used in engineering drawings to illustrate a structure as if it has been divided along another imaginary plane or cut into halves such as a vertical or horizontal plane. This technique is usually used by engineers and architects to show the details of the component and interior design of an object.
Hence, sectioning helps to give a view of the hidden part of an object through a cutting plane.
