midplane

Bisecting flat surface

The midplane is an imaginary plane that divides something into two equal halves, typically passing through the center.

In anatomy, the midplane bisects the body into left and right portions.

In engineering and physics, it refers to the central plane of a structure or field: The stress is highest at the midplane of the beam.

In 3D modeling and design, the midplane serves as a reference for symmetrical construction.
