I’m trying to develop a tool for slope risk analysis with 3D models like showed in the image below. In this 3D model, the slope faces oriented in the same direction and with the same inclination have the same colour. I know how to generate the 3D model from a point cloud captured with a drone, but I'm struggling to find a way to classify the slope faces. I'm trying to use ArcGIS Pro and Autodesk Civil 3D for this purpose, as I'm avoiding coding at this point. Any idea how to achieve that?
