FF/FL Extract floor

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.
