Detailed Description

Describes a MultiPointConstraint used in a Multiline. MultiPointConstraints are composed of several two or three-dimensional points. The purpose is to define the corresponding points that share a common constraint in order to compute the approximation of several lines in parallel. Notes:

The order of points of a MultiPointConstraints is very important. Users must give 3D points first, and then 2D points.
The constraints for the points included in a MultiPointConstraint are always identical for all points, including the parameter.
If a MultiPointConstraint is a "tangency" point, the point is also a "passing" point.
