Impossible to read correctly a big size Cloud

Hello,
I frequently use Metashape to create point clouds, which I then export as XYZ, PLY, LAS or OBJ files and work on with CloudCompare.
Today, I created a cloud with 196,978,930 points and generated XYZ,OBJ files, each around 15 GB in sizeand a PLY file (6 Gb). However, when I open any of these files in CC, only a single line is displayed on the screen, which is not at all what I get in Metashape.
Could this be due to the size of the file?
Thank you in advance for any help.
Jean

No, it looks more like a coordinate system issue. You may have generated the entities or files with a Geographical coordinate system. Which uses angles for X and Y, and meters for Z. So the scales are very different (and CloudCompare only handles cartesian coordinate systems).
