Trying to build a Tree like Sculpture - Please need some help!

Hi Guys, I'm really bad at grasshopper, but I'm not bad at rhino, What I'm trying to do is:

Get a "panel" to array along a given Curve, and follow it like a pine cone, and to give it a scale parameter so that from one length of the curve to the other it can change on the Z axis, and in a larger context all of the "Panels" to scale using some sort of curve chart depending where abouts the "pannels" are on the multi curve.

I'm sure it's not that complicated, but I'm retarded! Please see screenshot's to understand what I'm trying to explain lol

Thanks for reading!

This might get you started. You need 0.8.0050 to open the file.

wow thank you so much!

I removed the Ellipse input and changed it to a selected Curve I already had and that works great with one curve, but what If I wanted to select multiple Curves, it doesn't work right.

Also as the selected curve of mine I have already built isn't 100% on the X & Y, it also twists on the Z, so this has interesting factors on the final shapes, How can I compensate so the shapes follow the Z change? I appreciate I'm well over my head with this, but any words of wisdom would be great.

Yep, I forgot to Graft the curves. Fixed in the attached version. I also took a wholly different approach to make the angled panels, hopefully this time they have the angle you've been looking for.

Nice one, thanks for doing this! - Looking pretty awesome to me, Just a thought, How would you / I Make it so as they scale up and down so there is more of a noticeable "step" - and even possibly controlling Random spaces between the panels, but not every space, just random ones???

The height of the panels is now the same as the width. You can add your algorithm for determining the heights if you want that. For example you could measure the distance to the next curve over, use that to drive the panel heights.

As for randomness, that's a bit trickier. You could randomly shrink line segments, but inserting random spaces will be difficult because of the way the base curves are divided.
