Getting Started

This article will cover how to use the Floor Flatness tool within the Inspector Toolbar. The Floor Flatness tool allows you to create ASTM 1155 Floor Flatness/Floor Levelness runs and reports. To adjust settings for this function, refer to this article.

Creating Runs

After selecting the tool, left click two points to define the FF / FL run. You can also specify the length of a FF line by pressing a number on your keyboard after identifying your first point in the direction of your cursor.

After you place the first line, use the shift key and left click to place a parallel run line identical to the first. Additionally, you can hold Ctrl and left click to place a run identical in length, but perpendicular to the first.

After you finish laying down your lines, click enter and run the FF / FL report.

Reports

After the analysis has been run, a report will appear. On the left side of the report you will see numbers with the associated FF / FL values. On the right side, it shows the elevation values for each step.

FF numbers depict the Floor Flatness, or how wavy or bumpy a floor is.

FL numbers provide information about the Floor Levelness. Levelness is how closely the finished floor matches the intended slope.

To perform FF runs, Rithm will create Measure Locations periodically along the line. If you check the Show Measure Locations box, Rithm will display these points along the run.

The Show Visual Graph checkbox displays the visual graph of the profile of elevation values along the run. The 0 value is always the first point. Red is above and blue is below the zero elevation.

Following the options, the Create Report button in the Floor Flatness tab will create the PDF report. If you would like to edit the screenshot that is produced in the report, simply change your view in the 3d view of Rithm (panning or zooming in or out) and then press the screenshot button in the Floor Flatness Report dialog.

Export

If you would like to export out your floor flatness lines you can do so by selecting the export button in the inspector toolbar. You can export these lines out as a .dxf file, or Floor Flatness lines. Floor flatness lines are a copy of the lines you produced in your original analysis which can be imported into another Rithm Project using the “Import FF/FL measurements” button at the bottom of the reports page.


Import FF/FL Measurements

To import FF/FL Measurements onto a pointcloud model, first open up the Inspector Toolbar. Once open, select the reports button and make sure the floor flatness tab is selected. Then click the Import FF/FL Measurements button. Browse and select the lines you exported previously, and then click yes.
