RIGID SURFACE
Third line:
1. The “word” START.
2. Local x-coordinate of the starting point of the lin e segments.
3. Local y-coordinate of the starting point of the line segments.
Fourth and subsequent data lines define the various line, circular, and parabolic segments (see below
for their format) that form the profile of the rigid surface.
Data lines to define surfaces created with TYPE=REVOLUTION:
First line:
1. Global X-coordinate of point a, the origin of the local system (see Figure 17.19–2).
2. Global Y-coor dinate of point a, the origin of the local
system.
3. Global Z-coordinate of point a, the origin of the local
system.
4. Global X-coordinate of point b on the symmetry axis (the local z-axis).
5. Global Y-coordinate of po int b on the symmetry axis (the local z-axis).
6. Global Z-coordinate of point b on the symmetry axis (the local z-axis).
Second line:
1. The “word” START.
2. Local r-coordinate of the starting point of the line segments.
3. Local z-coordinate of the starting point of the line segment s.
Third and subsequent data lines define the various line, circular, and parabolic segments (see below
for their format) that form the profile of the rigid surface.
Data lines that define the line segments that form the rigid 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 endpoint of the line.
3. y-coordinate of the endpoint 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 endpoint of the c ircular arc.
3. y-coordinate of the endpoint of the circular arc.
4. x-coordinate of the ce nter (origin) of the circular arc.
5. y-coordinate of the center (origin) of the circular arc.
