Hi guys
help please
In Rhino we can create regular stars from Polygon command. With the polygon component I don’t see how, or is there a component for stars.
Otherwise, how to force points to be aligned with other points. I don’t know if you see what I mean, look at the second picture, how to force the points A and B to be aligned with points 2 and 4.
thank you so much
hi, here is a way
star.gh (11.4 KB)
This code is adapted from one of the threads I referred to above, but it does not align the points for you, as you described. It was written for a different purpose and depends on the ‘shape’ slider to align those points manually. Will give it another look…

Thank you very much, I will see the definitions in detail, I think it will be perfect.

The star at 6 is just an example. But the difficulty is to find the right scale ratio to have the points alignment.

, but it works only for stars whose number is even, I used 3.5 for segments to have a star to 7 but it gives a star to 7 which is not regular. I’m afraid it takes more effort.
thank you very much
Good but How to control shape to have regular star (aligned points)
Thank you
Very good! Two minor quibbles:
Haven’t got a solution yet for #2 but it’s a common problem. Good job on the main issue here though.
@anikolo already answered that question.
thanks!
this guy has got me searching for concave polygon definitions in wolfram.
(nothing so far!)

Nickel Thank you very much
Thanks a thousand times to all for the efforts you are kind
Joseph_Oster
Perfect thank you very much
@anikolo gets primary credit for this one. Cheers.
yes to yours 
heyyyy!!!
it’s not about credit! it’s about having fun! (and not having a girlfriend hahahaha)
but thanks!
This is totally irrelevant to the original problem, but just in case anyone wonders why the ‘Radius’ sliders are not in the same sequence as the ‘Count’ sliders… It’s because of the order in which I connected the wires. That ambiguity can be avoided by using Merge to explicitly define the sequence of inputs. Highly recommended on complex code where sometimes, that sequence can make a big difference.
thank you Joseph_Oster for that precision
…and the mathematical way…
