To use this tool first open the builder tool bar, then select surfaces. Next, define the analyze area by left clicking points around the pointcloud. You do not need to connect your dots. Once you press enter, Rithm will close the connection.
Subsampling – Reduces the density of the point cloud to a specific grid spacing. This will cause a pseudo-point cloud decimation but will still ensure accuracy as good as if the pointcloud had not gone through subsampling. We recommend a 1 inch decimation for most projects.
Grid spacing – Specifies the spacing of the area Determines the effect of the debris filter by specifying the area in which outlier points are searched.
Vertical Tolerance – After identifying outlier points, removes points greater than the defined distance in the vertical axis.
Horizontal distance – After identifying outlier points, removes points greater than the defined distance in the horizontal axis.
Coloring Mode – Determines if the coloring is based on High/Low elevation intervals or Cut/Fill amounts.
Cut/Fill Tolerance – The elevation above and below the base elevation that determines if the point should be cut or filled if the Coloring Mode is Cut/Fill.
Coloring Interval – The elevation interval between the colored bands if the Coloring Mode is High/Low.
Elevation Mode – Determines how to show the elevations values; either as Absolute Elevations, or Relative Elevations from the Base Elevation.
Max # of coloring intervals – Determines the number of color intervals used to color the point color if the Coloring Mode is High/Low.
Base Elevation – If you check this option, the value specifies the base elevation from which the High/Low or Cut/Fill areas are measured. If you uncheck this option, the base elevation is halfway between the highest and lowest elevation in the selected area.
Once you have your desire settings, click apply. The debris filter dialog and heat map settings dialog will open, and you analysis will display over your pointcloud. You can close out the debris filter dialog and heatmap settings dialog. You can access these dialogues again through the layer selection drop down menu found in the inspector toolbar edit button.
Use the export feature in the builder tab to export the map as a .xyz file. Once exported, you can open the .xyz file in Recap, save it as an RCP file, and then append it into your Navisworks project.
