			== Alternative / more general method ==
			Since version 2.9, it is possible to use the 'plane edition' dialog to change the orientation of any plane thanks to the dip / dip direction convention (see [https://en.wikipedia.org/wiki/Strike_and_dip]), and then retrieve the corresponding transformation matrix in order to apply it to any entity with the [[Apply_Transformation \| Apply transformation]] tool.

			The following picture is a summary of how this can be done:

Procedure

New page

== Menu / Icon ==

This tool is accessible via the 'Tools > Level' menu or the [[Image:CcLevel_small.png]] icon in the left toolbar.

== Description ==

This tool lets the user pick three points on a (horizontal) surface so as to rotate the cloud and make the corresponding plane parallel to the (XY) plane:

[[Image:Cc_level_in_action.jpg|frame|center|'Tools > Level' in action]]

== Procedure ==

Select one or several entities (clouds or meshes) or a group of such entities then start the tool.

A message will appear at the bottom left of the 3D view ("''Pick three points on the floor plane (etc.)''"). Simply click on the (floor) plane in three different places. Once the third point is picked, CloudCompare will automatically transform the selected cloud(s) so as to make the plane defined by the 3 points ''horizontal''.

Notes:
* try to pick the points as far as possible from each other to optimize the plane orientation 'accuracy'
* you can cancel the process any time by clicking on the tool icon again
* the first clicked point will be used as origin for the new coordinate system. The vector between the first and second clicked points will be the new 'X' dimension.
* this tool modifies the selected entities directly. You may want to clone or save them prior to call this tool.
