Flat Plane (FPLA)

A FPLA has an attribute POS, which defines a 3D, point through which the plane passes, and an attribute NORM which defines the vector normal to the plane. The retained side is that towards which the normal points. The basic command syntax for defining an FPLA is:

NEW FPLA

POS @

NORM direction

The NORM direction can be any standard direction, for example, N45W, ISO2, or can be by reference to a Design element p-point, in which case the result will be stored as a 3D vector and the reference will be lost. Figure 5:5 below illustrates the use of a flat Plane, positioned at the pump coupling and with a NORM direction of N45W.
