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"
nic.
Solved! Go to Solution.
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

Hi,

for some reason, using parameters in the equation, it doesn't allow to the "t" to take values different form 0 to 1.
If you can, file a bug report with PTC. It looked to me from the recent help files that they intend that any of the usual axes could also be used as the independent variable - such as X, Y, Z, R , theta, et al. and not just T. So somehow they determine how to switch; I don't see a selection in the TO and FROM header to tell how the selection is made, so maybe there's a bug.
I'm not so sure if it is a bug or not. I preatty much suppose it doesn't react as I expect, that's for sure.
That's why I'm attaching to images if someone knows if there si something wrong in the equation and maybe Creo treats the equation as it should.
I don't know how to file a bug.
