#Creation of a Geneva Wheel with Parametric values By: Isaac Ayala (drei) & Mark Stephen (quick61)
#This Macro creates the main parts of a Geneva Wheel Mechanism
#It depends on six values that must be altered in the following code
#The variables are a, b, n, p, t and h.
#Definition for each variable
# Input
#a = Drive Crank Radius
#b = Geneva Wheel Radius
#p = Drive Pin Radius
#t = Geneva Wheel Tolerance
#h = Geneva Wheel Height
#n = Driven Slot Quantity
# Output
#c = Distance Between Centers
#s = Slot Center Width
#w = Slot Width
#y = Stop Arc Radius
#z = Stop Disc Radius
#v = Clearance Arc
#Please note that you can alter the code so it depends on five values exclusively
#Just replace c, and either a or b with the following
# Keep value for a
#c = a/math.sin(math.pi/n)
#b = math.sqrt((math.pow(c,2))-(math.pow(a,2)))
# Keep value for b
#c = b/math.cos(math.pi/n)
#a = math.sqrt((math.pow(c,2))-(math.pow(b,2)))
