import several point cloud .txt

[claireera]

Hello,
I'm a begginer with cloudCompare, I m trying to import two point clouds of a same area in order to compare them. Both are in .txt.
When i import one point I can't see anything although I get more than 2000 points downloaded. I can't zoom on it because there is no boundaring box.
How can I build one?
Is anybody as an idea of how can i figure with, It will be a good help, thanks.

Be sure that the decimal character is the point and not the comma. The loaded cloud bounding box should be valid (see the cloud properties).

Otherwise you can send me the file and I'll check what's going on (to cloudcompare [at] danielgm.net - replace the [at] by @).
