Recreating a shape (set of related curves) in Grasshopper

Hi guys,

I am at beginning of the beginner level
So it might be very simple and obvious task, but I'm feeling I am in trouble with it

I would appreciate any of your help (suggestions, references to tutorials dealing w/ similar cases etc) on achieving the following.

1. Recreate this shape below, let's call it a circle with hooks (it's a set of curves I assume?)

2. By modifying the shape of one 'hook', all of them should change in the same way.

I made several attempts, but I can't get it to work and looks like I am nowhere in the vicinity of what needs to be done... .gh file attached.

Sorry if I am missing any info/attachments needed to answer my question. Will add, just lmk.

Thanks much for your advice.

This isn't quite right, but perhaps someone else here will know how to fix it.

Hi.

Check this as well. And make sure to check your GH's "Gumballs" option(Display-->Gumballs).

Hyungsoo - your solution is far more elegant than mine (of course), but I discovered that it changes the scale of the hooks simply as a result of changing the count.

But there is no scale component in your solution - so I'm hoping you can explain how/where the scaling happens.

Thanks.

@Birk

doesn't THIS component scale the hooks?

Hi. Birk.

Orient Direction component has two direction vector inputs(refrence & target).

If you use the unit vectors of them, then, there's no scaling happens.

But I used different lines as vector inputs, so that can make scaling happen.

Thanks a lot, Hyungsoo! I was wondering if there is a way to get rid of the zillion points I initially had, and Your solution show ..and also much appreciated that you provided the solution where the circle "breaks" This is one of the things I will make a use of.

Hyungsoo - Thanks for pointing out how Orient Direction can both orient and scale at the same time. This was not obvious to me at all.
