Using Point Cloud and Terrain Themes in Autodesk InfraWorks


In the video above, we take a look at theming point clouds and terrain surfaces to get visual information on terrain data.

In this example, we are using an RCP file created from an LAS file in Autodesk’s ReCap program with an IMX file created in AutoCAD Civil 3D as the ground base.

Users can theme point clouds by selecting the “Build/Manage” icon and selecting the “Analyze Your Model” option.

Selecting the “Point Cloud Themes” option will open a dialog box, where users can create a name for the theme and select an analysis type. For the example in the video, we’ve selected the “Classification” analysis based on the return classifications.

In our example, elements such as vegetation and the ground were colored vibrantly to stand out.

Palette themes can be chosen by selecting the color next to the listed classification in the Point Cloud Themes window. These palettes can be changed as a group by selecting the “Palette Type” drop-down menu in the Theme Properties dialog box.

Unclassified points can be colored as well by selecting the color associated with the “Unclassified” and “Created, never classified” classifications.

Users will need to create a terrain theme to create a classification for the ground surface.

Users can do this by selecting the Build/Manage icon and activating the “Terrain Themes” option. Within the Theme Properties dialog box for terrain themes, users can create a name for the theme and select the analysis type.

For the tutorial’s example, we’ve selected “Elevation” and have changed the palette type to something more visually appealing and informative to help illustrate elevations.

Users can more effectively analyze data from a terrain model with combinations of point cloud and terrain themes within InfraWorks.
