There are other types of coordinate systems that can be used to mathematically map a physical object.

  • A Polar coordinate system maps points in a two-dimensional space using a radius and a rotation angle (r, theta).

  • A Cylindrical coordinate system maps points using a radius, a rotation angle, and an elevation (r, theta, z). The origin in this system could be considered the center of the bottom of a cylinder. Cylindrical coordinates are convenient to use when there is an axis of symmetry in the model.

  • A Spherical coordinate system maps points using a radius and two rotation angles (r, theta, phi). The origin in this system could be considered the center of a sphere. Spherical coordinates are convenient to use when there is a point which is the center of symmetry in the model.

Typically, none of these coordinate systems are easily used to map piping systems. Most piping software deals exclusively with the Cartesian coordinate system.
