Rebuild arc with new diameter

Hi !

I want to rebuild arc with a new diameter, so I did this little tool :

arc.gh (13.6 KB)
arcs-2pt.3dm (798.1 KB)

I collect the original radius and find a new one on a list using “find closest point”, it’s maybe a little bit tricky, but it work.

My real problem is :
How can I rebuilt arcs using start and end point and the radius (like with the basic rhino tool “Arc” start, end , radius)…

any help will be apprecied !! thanks

make sure to internalize your data so you dont need an extra 3dm file.
i simply joined the curves & fetched their mid points.

Check this as well.

thanks for helping guys but both of your solution only allow me to rebuilt the same arc with the same radius

waht I want is to apply the new radius to a new arc using the same end point and start point that the old one was using…

Thank you very much HS_Kim

I did try to merge your tool with mine recalculating the arc angle… but at the end the diameter didi not correspond
It’s a tool to allow me to creat rounded and standard value to bend tube.
So i want the final radius of the new arc to be equal to the desired radius…
