Hello,
I agree with PeterGuy about associativity.The radius would suffer most changes for sure and a new involute is updated immediately.
Thanks Kapitan for explanation and the links.
Definitely you are the master of explanations.

Yes PeterGuy you mentioned before but I couldn't find this example first.I didn't expect to name this in doc "Creating a Parameterized Curve".
Anyway I gave you a star.

Hi again
I'm stupid, I just realized the same method is in doc at:
Creating a Parameterized Curve
but has a strange name for a curve from equation.

Hi
Finally I succeeded to make the involute in Catia.
I did one law (law1)for the x formula:
x=r(cos(t)+t*sin(t))
and than another law (law2)for the y formula
y=r(sin(t)-t*cos(t))
Using parallel curve to apply the law to a line (with advanced option) and indicate the law#1 I created a curve in...
Yes it's true Itsmyjob ,the points are calculated in EXCEL and a spline through these points are made in CATIA.It'd be nice to have a function like 'spline/curve from equation' as UG or ProE has.
I'm still thinking about the law procedure why I can't use 3 parameters...
Columb
Thanks PeterGuy for replay but the fog-law works with two parameters only, I have 3 parameters: x,y and angle t.
I'll try what Kapitan said.
Thanks Kapitan for your answer.It looks great.

Hello
How should I create a curve by equation?
The equation is the involute equation:
x=r(cos(t)+t*sin(t))
y=r(sin(t)-t*cos(t))
r and t are known and I can get the points(x,y)but I need to draw the curve.
Thanks
Columb
