Points along wave don't align at end/start

Hello everyone,

Can anyone tell me why my points don’t align (start to end)? I have lines projected in the Z axis along a closed curve. Point on curve and adjusted the points to give a wave pattern. The wave works, just the end doesn’t align with the start so I get a large gap from point 0 to 190 say.?

Image of what I mean is below along with the gh file.

Thanks if someone knows why and can help! :slight_smile:

And it looks like you forgot to internalize a curve param? (or is that due to the missing Relay component in R5?)

I was able to replace the missing R6 Evaluate Surface with R5 version, even though your screen shot doesn’t appear to match your GH model?

Thanks for you’re reply. The frustration in myself that I didn’t internalize the data!. Really sorry about that. here’s the .gh file with the curve internalized.

The trick is to make the graph curve start and end at the same place on y - axis.
Also, the part of your script in the pink group seemed unnecessarily complicated to me. So I simplified that part and put it in the red group just below.

Thank you! I knew it had something to do with the start and end of the curve, just couldn’t figure it out!

Really appreciate it… :slight_smile: You too @Joseph_Oster, thanks for your help.
