Arc blend in grasshopper

[arian.hakimi]

Hello,

I have been trying to replicate Rhino command Arc-Blend in grasshopper, and I tried Bi-Arc and as shown in the image it is unsuccessful. Does anyone have a better solution ?

Best,
A

Hi Arian,

would interest me as well,
I tried this but its not perfect; in my attempt the continuity between the arc curves is based on the bulgefactor
edit: i just checked and bi-arc seems to be working fine for me. maybe weird input geometry?

You could use Rhinocommon Curve.CreateArcBlend Method via C# or Phyton.

Bi-arc gives me no kink, just made random lines and used bi-arc. The tangents at the start/endpoints match.
