Surface Integration () to evaluate an integral over a set of domains in 2D, 2D axisymmetric, or boundaries in 3D.

|
Line Integration () to evaluate an integral over a set of domains in 1D, boundaries in 2D, or edges in 3D. Integrate over any dataset of the right dimension. For example, make a volume integration of a 2D revolved dataset or a surface integration of a cut plane.
