Points

The fundamental unit used in building problem domains is the geometric POINT.  POINTS in a FlexPDE script are expressed as a parenthesized list of coordinate values, as in then two dimensional point (2.4, 3.72). 

Since two- and three- dimensional figures both begin with a two-dimensional layout, the use for three-dimensional points is generally limited to ELEVATION PLOTS.

In one-dimensional systems, a point can degenerate to a single parenthesized coordinate, such as (2.4).
