This plug-in can only unroll the sheet metal model in Rhino®. The sheet metal model must meet the following conditions:

•The thickness should be same anywhere in the model.

•The join between any flange and leg must be cylindrical.

•The inner and outer cylinder surfaces must be coaxial.

You create the models inside Rhino or import the models created from other tools like Inventor or Solidworks. This tool will give you the bending lines, bending direction, actually drawing size based on the K-factor.
