BASIC QUESTION: is there a reason for which the "t" variable won't work in "curve from equation"?

Hi,

Is there a reason for which, in my case, the interval of variable "t" in curve from equation has NO EFFECT on my curve?

 

X=RING_GAUGE*pi*T
Y=RING_GAUGE/2*TAN(INCLINED_ANG:1)*(1-SIN(T*360+90))

 

One would expect that if I change the "t" value interval from "0 to 1" to "0 to 10" for example, I will have ten times the sine curve. instead is just one sine curve on the unwraped cylinder no matter what values I choose for "t"

Hi,

It was the INCLINED_ANGLE:1 parameter that was creating problems for some reason. Changing with a parameter from the INPUT bloc in the assy, it worked.

seems to be working fine in creo 4 M010, with t ranging from 0-1 or 0-10 or 5-10

We can also make ten times the sine curve by changing y value in equation to 

y=ring_gauge/2*tan(inclined_ang:1)*(1-sin(t*360*10+90)) 

while keeping the t within 0-1 range

for some reason, using parameters in the equation, it doesn't allow to the "t" to take values different form 0 to 1.
