LAS file not displaying points and No Returns

Hi Everyone,

I have a point cloud that was made from a drone flight using Pix4D. The point cloud will not display in ArcGIS Pro. I can see there are points in the file, it has elevations, but nothing showing up. The TOC shows Data percentage: 0.

I ran CheckLAS and I get the following:

Anyone have a clue what the problem is here and what I can do to get the points to be visible?

Cheers,

Additional information, the file is able to be rendered using Lidarview.com. Unfortunately, that does not seem to have any tools for processing or fixing whatever makes it not open in ArcGIS Pro.

This seems really dumb. I had to zoom in and then my points appeared. Literally a swipe on the scroll wheel on my mouse made them appear. No processing can happen unless points are visible. So the points were just ignored until zoomed in further. Then I could do everything I needed/wanted to do. If you have this problem, I guess try zooming in first.

Cheers,

Justin
