What three views are used in working sketches?

The correct response is based on the understanding that working sketches aim to provide a clear and comprehensive representation of an object in three-dimensional space. Using a combination of the top, side, and isometric views allows for an effective visualization that encompasses different angles and perspectives of the object being sketched.

The top view gives a direct overhead perspective, which is essential for understanding the layout and dimensions of the object as it appears from above. The side view contributes valuable information about the object's height and depth from the lateral perspective, which can also reveal interactions with other components or the surrounding environment. The isometric view enhances the representation by allowing the viewer to see multiple sides of the object simultaneously, facilitating a deeper comprehension of spatial relationships between different elements within the design.

In contrast, other combinations, such as featuring front, back, and side views, wouldn't adequately represent the depth or three-dimensionality unless paired with a perspective like an isometric view. Therefore, choosing the top, side, and isometric views provides a more complete and usable reference for anyone working with the sketch, enabling clearer communication and understanding of the design.
