Radius of an Arc?

[Juliensv]

Hello all,

 

This feels really simple, and I'm a bit embarrassed to ask the question, but how does one find the radius of an arc object?

 

vs.GetArc gives me startAngle and sweepAngle, and vs.HCenter will give me the centerpoint of the arc, but then how do I get a point on the actual arc to measure, without using PtOnArc or something ugly along those lines?

 

Thank you for your help!

Hello,

 

to solve problems like this i like to look into Marionette nodes. There is a Marionette Node "Get Arc" and the first output is the radius and this is how it was written in the node:

 

arcvalues = vs.GetArc(h)
perim = vs.HPerim(h)
sweepR = vs.Deg2Rad(arcvalues[1])
radius = perim / sweepR

 

Regards,

This is perfect! I didn't realize that HPerim on an arc would give the arc length. But it does make sense now that I think about it.

It's funny because I was actually trying to find the arc length of the arc in the first place...

 

Anyways thank you for the help, as well as the tip on looking in the Marionette Nodes!
