Looking to draw a flat spiral in creo parametric. Don't really know where to start. I have no experience with toriadial bends or spine tools if that's what you would use. Please help

paste the below equation,

x=(15+10*t)*cos(360*5*t)

y=(15+10*t)*sin(360*5*t)

z=0

explanation:

x = ( radius + increment * t * nrofturns ) * cos ( t * nrofturns * 360 )

y = ( radius + increment * t * nrofturns ) * sin ( t * nrofturns * 360 )
