# Walls and Floors

![CmdWallsAndFloors.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/CmdWallsAndFloors.svg)

This command splits points of a cloud into 3 or 4 categories:

- Walls,
- Floors and ceilings,
- Others.

> [!TIP]
> ### Requirements
> 
> Select the point clouds to split and launch the command.

1. Set the **angular tolerance** for **walls** (maximum angle with nadir-zenith line).
2. Set the **angular tolerance** for **floors and ceilings** (maximum slope).
3. You can change the slider for the **Local Normal Smoothing**. This slider allows you to increase or decrease the **radius of the influence zone on a cloud**, in order to take into account a bigger part of the cloud.
4. Choose the point clouds to create:
  1. **Walls** to classify the points which meet the threshold.
  2. **Floors and Ceilings** to classify the points which meet the threshold. Floors and Ceiling are also segmented when all inputs have scanning directions.
  3. **Other** to keep other points.

> [!WARNING]
> ### Notes
> 
> This command computes local point cloud normals to segment it. Consequently, any cleaning or segmentation done before may result in a slightly different segmentation.
