Downgrade Components (Rhino 5)

The Grasshopper shipped with Rhinoceros 6 introduces a bunch of new components, some replacing the most basic ones. This feature provides an one-click solution for downgrading them, so that it can be loaded by a Rhino 5 user. This feature will work without Rhino 6.

How to use this feature?

• Navigate to "Pancake" menu, click "Downgrade external script"

• Open an external Grasshopper file

Which component will be downgraded?

• Subtraction (with 2 inputs)

• Multiplication (with 2 inputs)

• Evaluate Surface

• Interpolate Curve (Tangent)

• Relay component

What are the possible results?

• Pancake encounters error when downgrading your file

  • Grasshopper script may be corrupt

  • Please contact us with the script file.

• Pancake cannot find any downgradable components

  • No components need to be downgraded

• Operation successfully completed

  • All components are downgraded

  • And, there is no Rhino 6 only component

• Some component(s) were downgraded successfully but some component(s) cannot be downgraded

  • Some component in the definition may be Rhino 6 only and has no substitution in Rhino 5

  • Some Sub/Mul component may have more than 2 inputs

What else should I also notice?

• To-be-downgraded script shouldn't be opened in the document editor.

• The downgraded file is saved as <OriginalFileName>_downgraded.gh in the original location. So the original location must be writable.
