Flatness and Verticality

Would you like to know how to check the flatness and verticality of a wall? How do I generate a cutting plane and precisely position this wall and get the points that do not belong to the plane. Thanks

Hi,

I would use the 'Scissors' tool first to isolate the part of the cloud that belongs to the wall (see https://www.cloudcompare.org/doc/wiki/i ... ation_Tool).

Another option is to use the 'Cross section' tool (see https://www.cloudcompare.org/doc/wiki/i ... ss_Section).

Then you can fit a plane on this subset of points with https://www.cloudcompare.org/doc/wiki/i ... =Fit_Plane, and eventually compute the distances between the points and the plane (https://www.cloudcompare.org/doc/wiki/i ... h_Distance).

Hello! Is there a difference between computing verticality through geometric features and computing verticality through fitting a vertical plane and calculating the distance?

[daniel]

If you refer to the 'verticality' in the 'Tools > Other > Compute geometric features', then yes, it's quite different. It only computes these parameters on a small local portion of the cloud (so it's as if small planes were locally fitted, instead of one big plane).
