# SinWave, damper wave, creating a loft, point-oriantation?

SinWave.dyn (24.8 KB)

Hello,

I want to create a sin wave first, i would like to create sweep ( or a bend with two profiles ).
To place a profile (triangle) i want to set my plane on a point , but can`t change the orintation of my planes.

in dynamo there is just a classic sin-wave… how do implement a damper sin Wave ? should i place some kind of increment in my forumula ? or is it more comlex ?

the tutorials for python are based on external simulation, but how do i deal with that with points?

Something like this perhaps?

This should get you started:

``````
x = 24..360*cycleCount;
a = amplitude;
xBase = DSCore.List.TakeEveryNthItem(x,2,0);
xVal = DSCore.List.Join([DSCore.List.Reverse(xBase),xBase]);
y = DSCore.List.ShiftIndices(
a*Math.Pow(Math.E,-xVal/360)* (Math.Cos(2*xVal)+Math.Sin(2*xVal)),
shift*(cycleCount*6)
);
crv =
NurbsCurve.ByPoints(
Point.ByCoordinates(x,y)
);

@JacobSmall ,

What are your imputs… ? integers? or even vales … between 0…1?

Number

Datetime.Now > Datetime.Components > `n%60*360`

Then run in periodic

it seems to be all points are at the same place…

i want to create points and generate a other curve thats mor smooth…

Was smooth for me, perhaps geometry scaling?
