Hi, Pierangelo, thanks for the quick answer.
I have tried both ways. In fact, I don’t know what should I expect. For example, LAB 4 says “Go back to the rayCloud view and add planar surfaces on the side of the sheds and regenerate the mesh. Do you see any improvements”. I do that, but I don’t see any change after regenerating the mesh, I see the green rectangle that I have created (that was there before regenerating the mesh), and nothing more. I would expect to see a new surface or something similar.
If I unmark the “deleted” group, all the cars appear again (that also happened before regenerating the mesh) so, what is the practical change that regenerating the mesh produces?
And some “ghost” points remain even when the group “deleted” is unmarked. But they seemed totally gone before regenerating the mesh:
How could I share the log file with you?
After processing step 3, the removed points are gone in the DSM, that does work at least.
I will be doing my Pix4D certification exam tomorrow, without possible delay.
