To enable, click on the 2D Area Roughness button in the Analysis section. This opens the Area Roughness side panel, which contains the controls for this function.

 

First, set the Area of interest for 3D parameter calculation. There are two options: Entire image or Restricted area. When Restricted area is selected, a yellow box on the Top View indicates the area currently being analyzed. This box can be moved by clicking inside the box and dragging it, or resized by clicking and dragging on one of the edges or corners.

 

Once an area has been defined, the software displays the values for several different parameters which are listed below. For more details on each parameter, including equations used to determine the values, see the Areal Parameters section.

 

For best results when measuring roughness, level the surface using the Level tool, apply a Filter, then apply the surface analysis.

 

Select which parameters are shown by clicking the Settings cog in the side panel. In the Areal Parameter Settings dialog box click the checkbox to enable or disable the desired parameters. To disable or enable an entire section of parameters, click the checkbox next to All Parameters for that section.
