# Basic Tutorial | Complete analysis of a concrete floor

In this command [Surface Levelness](/v1/docs/cyclone-3dr-surfacelevelnessc), you will find complete tools to inspect a surface. You can check the levelness of a floor, the verticality of a wall, the flatness of a road, the local slopes on a terrain.

## Check the levelness of a floor

> [!TIP]
> Open the file **SectionsBuildingPlan.3dr** ([download](https://www.cyclone3dr.com/download_helper.php?File=Cyclone3DRSampleData/SectionsBuildingPlan.3dr)). It contains one cloud of the walls and one cloud of the floor.

Show only the cloud **Floor**. Select it and go to [Surface Levelness](/v1/docs/cyclone-3dr-surfacelevelnessc). Choose the **Z** direction to check the levelness, uncheck **Offset value** and then click on **Preview**. The points of the cloud are colored according to their Z coordinate. You can now see the lowest points in dark blue and the highest points in red.

## Check the flatness of a surface

This command allows checking if there are bumps or holes in a planar surface. This check can be done on a horizontal surface like a floor, but also on any other surface.

Show only the cloud **Floor** and select it again then go to [Surface Flatness](/v1/docs/cyclone-3dr-surfaceflatnessc). Give the parameters to check the flatness: set **1 m** for the Ruler dimension and **0.02 m** for the tolerance. This means that if you put a 1 meter long ruler on the floor, you expect no point from the floor to be further than 2 centimeters from the ruler.

Click **Preview**. We can see here that 99.5% of the floor matches the tolerance. This means this floor is flat regarding this tolerance. There are only a few red and blue points where the posts and walls are.

## Check the local slope on a surface

The last command allows measuring the local slope on each point of a cloud or a mesh.

Show only the cloud **Floor** and select it again then go to [Slope Analysis](/v1/docs/cyclone-3dr-surfaceslopeanalysisc). Set **4%** as the **maximum slope tolerance**. In this way, you will check that the entire floor does not contain a zone with a slope higher than 4%. Set the **local normal smoothing** cursor in the middle to compute the slope on zones that are approximately 40 cm wide. Click **Preview** to preview the results.

We can see that red zones are only where there are walls and posts.
