# FF Shape

![](/files/gLXojYx9GM7lMiA4S3OS)

Create Fairyfly Shape.

### Inputs

* **geo \[Required]**

Rhino Brep or planar Polyline geometry.

* **material \[Required]**

Optional text for the Shape's THERM material to be looked up in the material library (see the "FF Search Materials" component for a full list of materials that ship with THERM). This input can also be a custom SolidMaterial or CavityMaterial object created from the corresponding component. Lastly, it can be text for the name of a HB-Energy material to be looked up in the material library (see the ""HB Search Materials" component for a full list of materials that ship with Honeybee).

* **rgb\_color**

An optional color to set the color of the material when it is imported to THERM. All materials from the Fairyfly Therm Library already possess colors but materials from the HB-Energy material lib will have a randomly-generated color if none is assigned here.

### Outputs

* **report**

Reports, errors, warnings, etc.

* **shapes**

Fairyfly shapes. These can be used in THERM simulation.
