+Now you must specify what mode of creating plane you want to choose: 
+absolute or relative.
+
+<b>Absolute mode</b>
+
+\image html Clipping_Absolute.png
+
+- <b>Base point</b> - allows to define the coordinates of the base
+  point for the clipping plane.
+
+  - <b>Reset</b> - returns the base point to coordinate origin.
+
+- <b>Direction</b> - allows to define the orientation of the
+  clipping plane.
+
+  - <b>Invert</b> - allows to select which part of the object will be
+    removed and which will remain after clipping.
+    
+<b>Relative mode</b>  
+

+- \b Orientation ( ||X-Y, ||X-Z or ||Y-Z).
+- \b Distance between the opposite extremities of the boundary box of

+Also, it is possible to specify the type of clipping: using dataset, 
+i.e. it only changes the visibility of separate mesh cells or alternative 
+clipping - an OpenGL native one, which clips overall presentation.
+For choosing use <b>OpenGL clipping</b> checkbox.
