Sine Curve?

Hi everyone

I wanted to know how to create a sine curve between 2 or 3 points? I have tried 3point arc but thats not the effect what I want. So I would be grateful if anyone could answer!

Thank you

Have you tried the Sine Curve example in the Primer? Would this do what you need?

Thanks for the reply Andy! Actually the example in primer uses a range to create a set of numbers. But what I want is to draw a sinusoidal curve between 2 or 3 given points. When I tried to use range again, the points were created near the origin and not using the given points.

Try to build a guide line first between these points, divide that curve and move the points along perpendicular vectors.
Just an idea, I don't know if it works.
Bye!

Thanks Andrea. That would be an interesting way to approach the problem. But I feel there must definitely be a way to do it 'right' and I don't know it because I'm a beginner.

Yes, Andrea is correct. Something like this should work.

I tried to post this solution... but I'm not sure if it worked properly. But, Andrea is correct. Something like this should work.

Hey Andy

I tried using the exact definition like you said. I have 2doubts.

1 - When I try to apply this component onto a surface in a different plane [ex: the component is in x-axis and the surface is in z-axis], it doenst work.

2 - It doesnt apply smoothly when applied to an uneven surface [ie not a perfect rectangle/ square]

How do I solve this?

Many Thanks
