## Inputs

* **depth \[Required]**

  A number for the depth to extrude the louvers. 
* **shade\_count**

  A positive integer for the number of louvers to generate. Note that this input should be None if there is an input for *dist\_between*. Default: 1. 
* **dist\_between**

  A number for the approximate distance between each louver. Note that this input should be None if there is an input for *shade\_count*. 
* **facade\_offset**

  A number for the distance to louvers from the Wall. Default is 0 for no offset. 
* **angle**

  A number for the for an angle to rotate the louvers in degrees. Default is 0 for no rotation. 
* **vertical**

  Optional boolean to note whether the lovers are vertical. If False, the louvers will be horizontal. Default False. 
* **flip\_start**

  Boolean to note whether the side the louvers start from should be flipped. Default is False to have contours on top or right. Setting to True will start contours on the bottom or left.
