Create Dragonfly Room2Ds from floor plate geometry (horizontal Rhino surfaces).

### Inputs

* **geo \[Required]**

A list of horizontal Rhino surfaces or closed planar polylines representing floor plates to be converted into Room2Ds.

* **flr\_to\_ceiling \[Required]**

A number for the height above the floor where the ceiling begins. Typical values range from 3 to 5 meters.

* **name**

Text to set the base name for the Room2D, which will also be incorporated into unique Room2D identifier. This will be combined with the index of each input \_footprint\_geo to yield a unique name for each output Room2D. If the name is not provided, a random one will be assigned.

* **program**

Text for the program of the Room2Ds (to be looked up in the ProgramType library) such as that output from the "HB List Programs" component. This can also be a custom ProgramType object. If no program is input here, the Room2Ds will have a generic office program.

* **constr\_set**

Text for the construction set of the Room2Ds, which is used to assign all default energy constructions needed to create an energy model. Text should refer to a ConstructionSet within the library such as that output from the "HB List Construction Sets" component. This can also be a custom ConstructionSet object. If nothing is input here, the Room2Ds will have a generic construction set that is not sensitive to the Room2Ds's climate or building energy code.

* **conditioned**

Boolean to note whether the Room2Ds have heating and cooling systems.

### Outputs

* **report**

Reports, errors, warnings, etc.

* **room2d**

Dragonfly Room2Ds.
