Final answer:
The isometric planes in AutoCAD are named isometric XY, isometric XZ, and isometric YZ, corresponding to the axes they are parallel to, facilitating three-dimensional representation on a two-dimensional surface.
Step-by-step explanation:
The names of the isometric planes in AutoCAD correlate with the axes of the three-dimensional space where objects are modeled. The planes are named after the axes they are parallel to, namely, the isometric XY, isometric XZ, and isometric YZ planes.
The isometric XY plane is parallel to the X and Y axes, primarily used for the top view in isometric drawings. The isometric XZ plane is parallel to the X and Z axes and typically shows the side view. Lastly, the isometric YZ plane is parallel to the Y and Z axes, often representing the other side view not shown by the XZ plane.
In isometric projection, these planes allow for a three-dimensional representation on a two-dimensional surface, giving the observer a comprehensive understanding of the object’s dimensions and relationships.
