Final answer:
A sectional axonometric drawing is a type of architectural drawing where the cutting plane is bent to show all significant interior details across multiple planes. It provides a comprehensive view and is distinct from other types of section drawings that follow a single plane, like longitudinal sections in buildings or transverse sections in medical scans.
Step-by-step explanation:
A sectional axonometric drawing is a section view drawing in which the cutting plane is perpendicularly bent to pass through all important interior details. This type of drawing is useful in architecture and engineering because it allows for a comprehensive view of a structure's complex interior elements by representing multiple planes in a single image. In this context, the cutting plane is manipulated in a way that can show various sections of a building or object, even when those sections are not aligned along a single axis.
An example of this can be seen in a longitudinal plan, typically seen in architecture, where the design is arranged along a single axis that culminates at a focal point, such as an altar. Unlike a longitudinal section which would cut along this axis, a sectional axonometric drawing could show multiple planes and detail. Understanding this concept is also important in fields like medicine where different planes, such as the transverse (horizontal) plane, are used to interpret scans and body sections accurately.
