I assume that you're utilizing the method we've provided to generate the footprint from the single building point cloud. Just a friendly reminder to ensure that the ground height is set correctly and not relying on the default value of -5.97 we've provided, as it may result in the footprint being positioned above the roof points which is definitely incorrect.

CLI_Example_2 main.cpp line57 double ground_height = -5.97;// the ground height value should be set correctly
