*SURFACE
3. Local z-coordinate of the starting point of the line segments.
Third and subsequent data lines define the various line, circular, and parabolic segments (see below
for their format) that form the profile of the analytical surface.
Data lines that define the line segments that form the analytical surface for TYPE=SEGMENTS,
TYPE=CYLINDER, and TYPE=REVOLUTION:
Data line to define a straight line segment:
1. The “word” LINE.
2. x-coordinate of the end point of the line.
3. y-coordinate of the end point of the line.
Data line to define a circular arc segment (the arc must be less than 180°):
1. The “word” CIRCL.
2. x-coordinate of the end point of the circular arc.
3. y-coordinate of the end point of the circular arc.
4. x-coordinate of the center (origin) of the circular arc.
5. y-coordinate of the center (origin) of the circular arc.
Data line to define a parabolic arc segment:
1. The “word” PARAB.
2. Local x-coordinate of the middle point along the parabolic arc.
3. Local y-coordinate of the middle point along the parabolic arc.
4. Local x-coordinate of the end point of the parabolic arc.
5. Local y-coordinate of the end point of the parabolic arc.
For surfaces created with TYPE=SEGMENTS, the
x
- and
y
-coordinates are the global
X
- and
Y
-coordinates or
r
- and
z
-coordinates.
For surfaces created with TYPE=CYLINDER, the
x
- and
y
-coordinates are the local
x
- and
y
-coordinates. For surfaces created with TYPE=REVOLUTION, the
x
-
and
y
-coordinates are the local
r
- and
z
-coordinates.
