Question
Hello,
I would like to know how the point between vertices 1 &2, (0,0.212132,0), was obtained.
I understand that it is with the ordinate of this point we calculate the coordinates of other vertices in the same circumference.
Say I change the pipe dia, would this particular point remain the same, if not what is the expression to find the new value.

Thanks in advance.

Answers:

Since you already know the radius of the circle, you can determine its co-ordinates as: [r x cos(theta), r x sin(theta), 0)
By varying the value of theta, you can locate its different co-ordinates
