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 th e parabolic arc.

5. y-coordinate of the endpoint of the parabolic a rc.

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 w ith TYPE=REVOLUTION, the

x- and y-coordinates are the local r- and z-coordinates.
