Grasshopper

algorithmic modeling for Rhino

Arc in radians

Hello everybody, 

 

I have a problem with my grasshopper model, and I hope there's anyone who can help me with it. I'm creating a model for a project for my Masters degree, and am using grasshopper for the first time.

I have an arc which is defined by a base plane, radius and an angle domain in radians. Now, i want to use a slider to make the arc longer or shorter between this certain domain. I have tried a couple of things, but every time, the arc runs from 0 to the value in the slider, instead of toggling between the domain that I want.

 

Thanks in advance!

try this: an arc from a to b radians is an arc with a length of (a-b), rotated by a

stack using the "rad" to convert angles to radians ...
and setting the number slider to 0min and 360 degrees or whatever you want.

but do not understand your question
