Brief: This tool is applicable to point cloud data, raster data and model data, which calculates the angle created by the three picked points in 3D view and calculates the projection angle of three points on the horizontal plane in 2D view.
1. Select the first point of angle measurement by left-clicking. 2. Select the second point of angle measurement by left-clicking. 3. Select the third point of angle measurement by double-clicking. The projection angle of the three points on the horizontal plane will be rendered in the scene and the measurement result is displayed in a label as follows.
Note: This tool only works with point cloud data, raster data and model data. The "Back One Point" is only available before the measurement is stopped. The tool is available in the profile window too.
