Plane
Planes are surfaces with infinite area. These are often used to specify the machining surfaces and tool end surface location.
By Three Points
Syntax is
<symbol> = PLANE/ point1, point2, point3
PL1 = PLANE/ P1, P2, P3
By a Point and a Parallel Plane
Syntax is
<symbol> = PLANE/ point1, PARLEL, plane1
PL2 = PLANE/ PT1, PARLEL, PL1
By the Coefficient of a Plane Equation a X + b Y + c Z = d
Syntax is
<symbol> = PLANE/ a, b, c, d
PL1 = PLANE/ 0, 0, 0, 25
PL2 = PLANE/ 0, 0, 0, 10
