Arc Help

In rhino it's possible to draw an arc using a start point, end point, and radius. Does grasshopper have a button that does this?

thanks

Hi Joshua,

no, because Start-End-Radius is actually under-defined. It only works in Rhino because Rhino can fall back on C-Planes and view directions to figure out what you meant (and even then it still has to ask which of the two possible arcs you want to keep).

I can make a component which takes a plane, a start point, an end point and a radius and it will return both the possible arcs. But would that really be useful? How would you figure out which arc is the one you wanted?

David,

Maybe I should back up a bit. I was looking for something like the arc command to quickly connect points on two parallel rings. I would like to use arcs rather than lines, also the arcs must remain in the space between the two rings rather than transversing through the center of the rings.

I apologize if this does not make sense. I'm rather new to this and still trying to muddle my way about. I appreciate your response.
