Hello,
For some reason when loading this point cloud file it shows up as a straight line, I can zoom in and out, but I don't see the full extent of the cloud.

Re: Cloud Point showing up as a straight line
Hello, I'm not exactly sure what type of files you are using, but to give you a hint, I have encountered this type of issue before with files where the X, Y, and Z columns were not properly aligned. Make sure that the XYZ coordinates are correctly pointing to the appropriate columns in the table.
Re: Cloud Point showing up as a straight line
check xyz order during import
Re: Cloud Point showing up as a straight line
Also, a classical issue is if the points are expressed in a 'geographical' coordinate system with X and Y being angles, and Z being in meters (i.e. with a totally different scale). CC expects all 3 dimensions to be the same.

Re: Cloud Point showing up as a straight line
Thank you. How can I check or edit this upon import?

This is a Mavik drone scan processed in MetaShape and extracted as a point cloud file.PierreGEOSCAN3D wrote: ↑Sat Apr 20, 2024 8:08 pm Hello, I'm not exactly sure what type of files you are using, but to give you a hint, I have encountered this type of issue before with files where the X, Y, and Z columns were not properly aligned.

Re: Cloud Point showing up as a straight line
Make sure that you are using global shift during opening, if cc revommends it. It might be caused by large coordinate precision loss.
Re: Cloud Point showing up as a straight line
You'll see that right away by considering the scale/values in the X, Y and Z columns (angular values will be much smaller, and almost all the same)

Re: Cloud Point showing up as a straight line
here's what I see when importing. For some reason I don't have an issue when opening up this point cloud in Quick Terrain Modeler.

Re: Cloud Point showing up as a straight line
And what the bounding-box looks like once you've loaded the cloud?
There's good chances that Quick Terrain Modeler does manage properly geographic coordinate systems...
