This step helps to extract the points laying on the floor.

1. Click a seed point on the floor. The limit objects previously activated stay activated until this click, then a temporary limit box is used.
2. If using a CloudWorx cloud as input, define a **Maximum number of points** to convert from the box.
3. Optionally, adjust this limit box to focus on the area of interest. Use this possibility to speed up the extraction.
4. Set the **Extraction tolerance** to define the maximum deviation allowed between the points and a theoretical plane.
5. Click **Compute**: the points on the floor should be filtered out.
