Hi @anon39580149,

Sorry I missed this.

Is the question about Brep.CreateDevelopableLoft or Unroller.PerformUnroll? Or both?

Hi @dale

About Brep.CreateDevelopableLoft

The final shape don’t follow the arcs and create squiggly lines.

This is an example with Plasticity, there is an option to select a guide

Doe Rhino’s DevLoft command work any better then the RhinoCommon function?

No , the same result as Grasshopper
