Area measurement
Function Description: The area measurement tool uses a mouse click to draw polygons interactively, and will query the projected area in the polygon area. For the area measurement of 3D data, the current window will automatically switch to orthogonal projection mode.
Steps
1.Click on the Area
button in the Measurement toolset.
2.Use the left mouse button to click consecutively on the data points(minimum three points) to select, polygons will be drawn in real time, and the measurement results will be displayed in real time in the form of labels (as shown in the figure).
3.Double-click the left mouse button on the last point to be selected to complete the measurement.
4.Click the right mouse button to fall back one point before completing the measurement.
Note: This function is only for the area measurement of point cloud data. This function can only be used in orthogonal projection, and this function can only be used in the 3D view window.
