The Hummingbird Components are placed on the Extra tab in Rhino-Grasshopper The Hummingbird solution includes a set of components for Rhino-Grasshopper and an add-in for Revit called ModelBuilder. The ModelBuilder tool is part of a general purpose tools set called The WhiteFeet Tools for Revit, which may be installed separately, and can be used instead of the add-in component provided with Hummingbird.
