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 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 to enter the Rectangular Fence mode so that a rectangular fence can be defined by making two picks.

   2. Select Polygon to enter the Polygon Fence mode so that a polygonal fence can be defined by making multiple picks.

   3. Select Clear 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:

   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.
