This tool is accessible via the 'Tools > Fit > Plane' menu.<br />
<br />
= Description =<br />
<br />
This tool fits a plane on a point cloud and outputs various pieces of information such as the fitting RMS, the plane normal and even the geological ''dip'' and ''dip direction'' values.<br />
<br />
= Procedure =<br />
<br />
Select one or several point clouds then launch this tool.<br />
<br />
For each cloud CloudCompare will fit a plane primitive (the extents of the plane will be deduced automatically).<br />
<br />

<br />
<br />
In the console the following pieces of information will be output:<br />
* plane fitting [http://en.wikipedia.org/wiki/Root_mean_square RMS]<br />
* plane normal vector (with a positive Z coordinate by default)<br />
* [http://en.wikipedia.org/wiki/Strike_and_dip dip and dip direction]<br />
* a 4x4x transformation matrix that would make this plane horizontal (see the 'Edit > [[Apply Transformation]]' method to use it for instance)<br />
<br />
<br />
Notes:<br />
* the fitted plane is added to the DB tree as a child of the cloud<br />
* the plane primitive is a kind of 'triangular mesh'. Therefore you can select both the cloud and the fitted plane and compute the distance between them (with 'Tools > Distances > [[Cloud-to-Mesh Distance | Cloud/Mesh Dist.]]')</div>Daniel
