Each PLA is defined by 6 numbers: H_x, H_y, H_z (x, y and z components of a vector of arbitrary length perpendicular to the plane), V_x, V_y, V_z (coordinates of any point lying on the plane). The half-space "inside the body" is that from which the vector is pointing (i.e., the vector points "outside"). A PLA definition extends over a single line in default fixed format, and over two lines in high-accuracy body fixed format. Example in default fixed format:*...+....1....+....2....+....3....+....4....+....5....+....6....+....7..PLA 74 0.0 1.0 1.0 200.0 -300.0 240.0* (all points "below" a plane at 45 degrees in the y-z projection which* passes through the point x=200, y=-300, z=240 - note that for such a* plane the x value of the point is completely irrelevant - )The same example in high-accuracy body fixed format:*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+.PLA 74 0.0 1.0 1.0 200.0 -300.0 240.0 The same example in free format: PLA tiltPla 0.0 1.0 1.0 200.0 -300.0 240.0
