 \n Firstly, you can define a \b Cylinder by the <b>Base Point</b> (the central
 point of the cylinder base), the \b Vector (the axis of the cylinder),
 and its dimensions: the Radius and the Height.
-\n <b>TUI Command:</b> <em>geompy.MakeCylinder(Point, Axis, Radius, Height)</em>
-\n <b>Arguments:</b>  Name + 1 vertex + 1 vector + 2 values
-(Dimensions: radius and height).
+\n <b>Angle</b> checkbox and field allow defining an angle to build a portion of cylinder.
+\n <b>TUI Command:</b> <em>geompy.MakeCylinder(Point, Axis, Radius, Height, Angle=2*pi)</em>
+\n <b>Arguments:</b>  Name + 1 vertex + 1 vector + 3 values
+(Dimensions: radius, height and angle).

 \n Secondly, you can define a \b Cylinder by the given radius and the
 height at  the origin of coordinate system. The axis of the cylinder
 will be collinear to the OZ axis of the coordinate system.
-\n <b>TUI Command:</b> <em>geompy.MakeCylinderRH(Radius, Height)</em>
-\n <b>Arguments:</b> Name + 2 values (Dimensions at origin: radius and
-height).
+<b>Angle</b> checkbox and field allow defining an angle to build a portion of cylinder.
+\n <b>TUI Command:</b> <em>geompy.MakeCylinderRH(Radius, Height, Angle=2*pi)</em>
+\n <b>Arguments:</b> Name + 2 values (Dimensions at origin: radius, height, angle).
