Empty surface when trying to build from dense cloud, no matter what I do

[sergio]

Hi,

I am trying build a mesh from an imported pointcloud. I have correctly defined the bounding box so that the points are inside it (I have around 1million points). With any interpolation option, I get the "empty surface" error message. I've tried both using the GUI and by repeating this process on the python API, with no success...

Any help would be greatly appreciated.

Hello sergio,

Can you please provide the log from the Console pane related to the failed build mesh operation and a screenshot of the dense cloud in the Model view with the visible bounding box?

Hello Alexei, this is my output when trying from the API:
