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. A p-point or a p-line point can be used instead of a POS via standard attributes DESI, NPPT, PKEY and PKDI.

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 is stored as a 3D vector and the reference is lost.

The example illustrates the use of a flat Plane, positioned at the pump coupling and with a NORM direction of N45W.
