Section 5

spaced from 3 to 6. Hence, joint 4 will have coordinates of
20.25 0.0 8.5 and joint 5 will have coordinates of 35.25 0.0 8.5.
Example 2
JOINT COORDINATES
1 0.0 0.0 0.0 4 45 0.0 0.0
REPEAT 4 0.0 0.0 15.0
REPEAT ALL 10 0.0 10.0 0.0
Here, the 220 joint coordinates of a ten story 3 X 4-bay structure
are generated. The REPEAT command repeats the first input line 4
times, incrementing each Z coordinate by 15. Thus, the first 2 lines
are sufficient to create a "floor" of twenty joints.
1 0. 0. 0. ; 2 15. 0. 0. ; 3 30. 0. 0. ; 4 45. 0. 0.
5 0. 0. 15. ; 6 15. 0. 15. ; 7 30. 0. 15. ; 8 45. 0. 15.

17 0. 0. 60. ; 18 15. 0. 60. ; 19 30. 0. 60. ; 20 45. 0. 60.
The REPEAT ALL command repeats all previous data (i.e. the 20
joint "floor") ten times, incrementing the Y coordinate by 10 each
time. This creates the 200 remaining joints of the structure:
