Bolt Pattern
From my blog: http://edspi31415.blogspot.com/2015/03/h...ttern.html
The program BOLTPAT will calculate a bolt pattern given: X = center, X coordinate Y = center, Y coordinate N = number of bolts D = diameter of the circle No angle of rotation is assumed. Coordinates of each bolt can be calculated by: X_k = (d/2*COS(360*k/n)+xc) Y_k = (d/2*SIN(360*k/n)+yc) Where k = 0 to n1 The OCDistance between each bolt is calculated by calculating the linear distance between neighboring bolts. Output: Each point where the bolt should be placed. In addition, the oncenter distance between bolts is displayed. Finally, each of the coordinates will be presented in a list. Code: EXPORT BOLTPAT() Example: Build a bolt pattern with 5 bolts of a circle of diameter of 3 units. The center of the circle has the center (1, 4). (X = 1, Y = 4, N = 5, D = 3) Bolts should be placed at the following points: (5.5, 1) (4.4635, 2.4266) (2.7865, 1.8817) (2.7865, 0.1183) (4.4635, 0.4266) OCDistance: 1.7634

RE: Bolt Pattern
This is my output with the given input:
x + y*i (2.5,4) (1.46352549156,5.42658477444) (−0.21352549156,4.88167787844) (−0.21352549156,3.11832212156) (1.46352549156,2.57341522556) OCOC: 1.76335575688
