Hi there

how can I draw an Arc with constant length and with different radius of arc in GH? in Arc component in grasshopper when I change the Radius, the length of arc will be changed. I want to have the constant length.

Math!

`s = 2 Ď€ r (Î¸/360Â°)`

*(if Î¸ is in degrees)*

The length of the arc is directly related to radius and angle of the arc.

thanks @Joseph_Oster and @seghierkhaled , i think itâ€™s better i say that i want a curve, because, i want with change of radios , the curve go more curved. i want to have a curve with the constant length and with various radios and constant start and end points

thanks in advance for your help

In other words, you want a spiral. Search the forum for â€śspiralâ€ť:

sorry, unfortunately it didnâ€™t work to me.

If an approximation with the catenary is not enough for you, you should explain better what you want, since what you have said can be interpreted from having no solution to having infinite solutions.

You should spend more time asking questions than people answering you.

A sketch would be helpful

Yessss!!! That was my answer that l was looking for that

l really appreciate @Dani_Abalde , you are best! this is so practical
