How to determine the lenght of an arc
-
I'd like to draw an arc of a predetermined lenght. Is there a simple way or a plugin to get it quickly without doing math every time?
Thanks,
Luca

I doubt it since there are an infinite number of arcs you can draw at a predetermined length. Remember you need both the angle and radius.

Well, the native SU arc tool allows specifying the chord length, the segment count and the bulge or radius but not the arc length.
Knowing the chord however, you could define (mathematically) an arc length, too so I guess it could be done with ruby (but please, do not ask mehow)

Try this ArcByTools script http://forums.sketchucation.com/viewtopic.php?p=365402#p365402
It draws arcs of a specified radius/length/segments - calculating the swept-angle
or of a specified swept-angle/length/segments - calculating the radius. -

Yes, that's what I meant
@TIG: Thank you TIG, that's a useful plugin for me.

Hi,
I have to test this new Tig's tool which seems perfect for the purpose.
I just wanted to remind and connect readers with the same request I had in times and which can complete the purpose: Can i draw an arc with a specifying circumference value
And especially to focus on a calculator linked by Pilou

Hi Simon,
Thank you for this hint, it will be very useful, too!
