# Floor Flatness

## **Tools | Floor Flatness**

### **Command Line**

- **AutoCAD / BricsCAD: CWFLOOR**

This command displays the **Floor Flatness / Floor Levelness** dialog, which enables the user to define a test area and then create a template to test for floor flatness and floor levelness.

The tool calculates the Floor Flatness and Floor Levelness values of a finished floor from point cloud data, according to the ASTM E1155 standard.

### **Using the Tool**

To perform a Floor Flatness Analysis:

1. Click the **Floor Flatness** button in the **Tools** panel or type a [command line prompt](/v1/docs/cloudworx-floor-flatness#command-line) specific to the preferred CAD system and press **ENTER**.
  1. The **Floor Flatness / Floor Levelness** dialog will open.

2. Define the test area:
  1. Select **Rectangle**![image-20240327-134423.png](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/image-20240327-134423.png) to enter the Rectangular Fence mode so that a rectangular fence can be defined by making two picks.
  2. Select **Polygon** ![image-20240327-134455.png](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/image-20240327-134455.png) to enter the Polygon Fence mode so that a polygonal fence can be defined by making multiple picks.
  3. Select **Clear**![image-20240327-134515.png](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/image-20240327-134515.png) to remove a previously defined fence.
3. Specify the **Test Area Offset** and **Interval** values:
  1. **Test Area Offset**: This parameter is used to exclude points that are too close to the fenced area to avoid their inclusion in the test area.
  2. **Interval:** This parameter determines the spacing between sampled points that fall along the Run ID - Line. The default value is 1, which is the US standard.
4. Place the template:
  1. Once the area has been fenced, select the desired **Place Template** option, then make two picks within the fenced area to define the first path of the test template.
  2. The tool will extract a ground elevation every 1 foot down all four lines of the template.
  3. Once the data is extracted, the results are computed, and a report can be generated.
5. Generate a report:

> [!NOTE]
> **Note:** To replace the "Floor Flatness & Floor Levelness ASTME1155 FF & FL" image in the upper-left corner of the report, upload the desired image in the PNG format to the corresponding CloudWorx **ProgramData** folder, and rename it as FloorFlatnessLogo.png.
  1. Specify the **Overall Floor Flatness (FF)** and **Floor Levelness (FL)** values, fill in the **Report Title** and **Author** fields, and click **Generate Report**. The report will be saved as a PDF file to the selected location.
