What type of shading method would you use in a technical drawing to show depth?

Tonal shading is an effective method to indicate depth in technical drawings due to its ability to convey the perception of light and shadow. This technique uses varying shades of gray or color to represent the intensity of light falling on an object, helping users discern its three-dimensional form and surfaces. By applying darker tones in areas that would naturally be in shadow and lighter tones where light hits, tonal shading enhances the overall visual understanding of the object’s shape and contours, making it appear more realistic and providing a clear sense of depth.

The other methods, while useful in their own contexts, do not provide the same level of clarity for illustrating depth. Line shading relies on varying line weights and patterns, which can suggest texture but may not effectively depict the gradient of light and shadow necessary for showing depth. Gradient shading, although it can create smooth transitions between colors or values, may not offer the same structural clarity as tonal shading. Color shading introduces hues which can distract from the intended depth perception unless used very carefully. Thus, tonal shading stands out as the most effective choice for representing depth in technical drawings.
