+(3) Use hotkey (S) to switch on polygon selection, select incorrect polygons.
+
+(4) Open Paraview Selection Display Inspector, select the Point Labels and ID. The selected Polygons will now show their coordinates.
+
+(5) Open the .vtp file in a text editor and search for the three numbers seen in Paraview. Switch the 1st and 3rd numbers.
