Thank you very much for the help provided.

In fact, I need to attach a flat plane to a surface.  
And this surface is in a point cloud, but first I think I should turn it into a Mesh.

Note: I recorded the pathologies of a tunnel in a reflected plane, 2D.  
 And this tunnel is in the form of a point cloud arch.  
 The Pathologies were recorded in a 2D plane of the Reflected Tunnel  
Now I need to draw or attach these pathologies to the Tunnel plan which is an Arc, following the contour lines.  
Ex:
