Clicking the Plane button in the Extract Panel of the Action Tab will put the current mode into Plane Extraction mode.
Planes can be extracted in any rotation of the scene. The scene may be of a Cloud or Scan.
The size of the plane is controlled by two parameters.
The Evaluation radius defines how far from one point to look at other points for points that meet the Standard Deviation Threshold.
Standard deviation threshold is how far a point can be away from the plane for the plane to be considered flat. A value of about 20% of the Evaluation Radius is typical.
The Create shrink-wrap droplist has three options.
Full creates a 3D polyline that encloses the points used to create the plane.
Bottom creates a 3D polyline
None: No polyline is created. This is the default option.
The Plane points droplist has three options.
Select: Adds the points used to create the plane to the active selection set. The points are highlighted in red. This is the default option.
Hide: removes the points used to create the plane from visibility in the scene.
Leave: The plane is created without highlighting or hiding the points used.
The Undo option undoes the last function performed. For example. If you create a plane and have selected the Plane points "hide" option, Undo would restore the points to being visible. Your plane would still be in the scene. Undo only performs one operation. You cannot undo multiple steps.
After these options have been set to the preferred values, the user can extract the plane by left clicking in the viewer while holding down the ctrl key. The plane is displayed in the active scene and can be drawn in CAD as a closed 3D polyline from the Project Tab.
