To create an \b Ellipse in the Main Menu select New Entity - > Basic - > Ellipse
-\n You can define an \b Ellipse by its Center Point, a \b
-Vector giving its normal, and its Major & Minor Radiuses.
+\n You can define an \b Ellipse by its Center point, a \b
+Vector giving its normal, another vector specifying the direction of
+ellipse's Major Axis and its Major & Minor Radiuses.
\n The \b Result of the operation will be a GEOM_Object (edge).
-\n TUI Command: geompy.MakeEllipse(Point, Vector, RadiusMajor, RadiusMinor)
+\note The parameters Center, Vector and Major Axis
+are optional. By default it is presumed that the Center point
+is located at the origin of the global coordinate system, the \b Vector
+corresponds to OZ axis of the global coordinate system and Major Axis
+corresponds to OX axis of the global coordinate system.
+
+\note The actual direction of the major axis vector is defined as
+ Vmaj' = (Vn * Vmaj) * Vn, where \em Vn is a normal vector and
+\em Vmaj is an original vector of the major axis.
+
+\n TUI Command (without the major axis): geompy.MakeEllipse(Point, Vector, RadiusMajor, RadiusMinor)
\n Arguments: Name + 1 vertex (for the center) + 1 edge (for
the direction) + 1 X Radius + 1 Y Radius.
-\note By default it is presumed that the Center Point is located at the Origin of the global
-coordinate system, and the \b Vector corresponds to OZ axis of the global
-coordinate system.
+\n TUI Command (with the major axis): geompy.MakeEllipseVec(Point, Vector, RadiusMajor, RadiusMinor, VectorMajor)
+\n Arguments: Name + 1 vertex (for the center) + 1 edge (for
+the normal direction) + 1 X Radius + 1 Y Radius + 1 edge (for the
+major axis direction).
