Basic Tutorial | Complete analysis of a concrete floor

In this command Surface Levelness, 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

Open the file SectionsBuildingPlan.3dr (download). 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. 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. 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. 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.

Now, you can create a pdf report with this analysis. Launch the Report Editor by clicking on the report menu in the ribbon. 4 chapters have been added to the report:
