*RIGID SURFACE
Data line to define a parabolic arc segment:
1. The “word” PARAB.
2. x-coordinate of the middle point along the parabolic arc.
3. y-coordinate of the middle point along the parabolic arc.
4. x-coordinate of the endpoint of the parabolic arc.
5. y-coordinate of the endpoint of the parabolic arc.
For rigid surfaces created with TYPE=SEGMENTS, the x - and y -coordinates are the global X - and Y -
coordinates or r - and z -coordinates. For rigid surfaces created with TYPE=CYLINDER, the x - and y -
coordinates are the local x - and y -coordinates. For rigid surfaces created with TYPE=REVOLUTION, the
x - and y -coordinates are the local r - and z -coordinates.
