This primer provides an overview of the Dragonfly components for Grasshopper.
The Dragonfly plugin supports the creation of models following the dragonfly-schema, which is an abstracted means of describing building geometry built on top of the honeybee-grasshopper plugin. By using a fundamentally 2D representation of Building geometry, where all rooms are assumed to be extrusions of floor plates, Dragonfly makes it easier to build models of large buildings all of the way up to the scale of urban districts. All Dragonfly models are translatable to Honeybee models and so all Dragonfly models can be simulated in the same engines as Honeybee, including EnergyPlus/OpenStudio and Radiance.
However, Dragonfly makes it easier to create these simulation models from common 2D formats like GeoJSON. It also enables the connection to a wider array of simulation engines including:
