\n Firstly, you can define the <b>Base Shape</b> (a basis of the
extrusion), the \b Vector (a direction of the extrusion) and the \b
Height of extrusion.
-\b <b>TUI Command:</b> <em>geompy.MakePrismVecH(Base, Vector, Height)</em>
+\n The \b Result of the operation will be a GEOM_Object (edge, face,
+shell, solid or compsolid).
+\n <b> Both Directions </b> checkbox allows extruiding the source
+object both forward and backward.
+\n <b>TUI Command:</b> <em>geompy.MakePrismVecH(Base, Vector, Height)</em>
\n <b>Arguments:</b> Name + 1 shape (vertex, edge, planar wire, face or
shell) serving as base object + 1 vector (for direction of the
extrusion) + 1 value (dimension).
\n Secondly, you can define the \b Extrusion by the <b>Base Shape</b>
and the \b Start and <b>End Point</b> of the \b Vector (in this way
you don't need to create it in advance).
+\n <b> Both Directions </b> checkbox allows extruiding the source
+object both forward and backward.
\n <b>TUI Command:</b> <em>geompy.MakePrism(Base, Point1, Point2)</em>
\n <b>Arguments:</b> Name + 1 shape (vertex, edge, planar wire, face or
shell) serving as base object + 2 vertices.
To create a \b Line in the <b>Main Menu</b> select <b>New Entity - >Basic - > Line</b>
-\n To create a \b Line you should define \b Point1 and \b Point2,
-which are the points through which the \b Line passes.
-\n The \b Result of the operation will be a GEOM_Object (edge).
+There are 2 algorithms to create a \b Line in the 3D space.
+The Result of each operation will be a GEOM_Object (edge).
+
+\n Firstly you can define a \b Line through \b Point1 and \b Point2,
+which are the points through which the \b Line passes.
\n <b>TUI Command:</b> <em>geompy.MakeLineTwoPnt(Point1, Point2)</em>
\n <b>Arguments:</b> Name + 2 vertices.

+
+\n Secondly you can define a \b Line as intersection of \b Plane1 and
+\b Plane2.
+\n <b>TUI Command:</b> <em>geompy.MakeLineTwoFaces(myFace1, myFace2)</em>
+\n <b>Arguments:</b> Name + 2 faces.
+

+
<b>Example:</b>
To create a \b Point in the <b>Main Menu</b> select <b>New Entity - >
Basic - > Point</b>
-\n There are three algorithms to create a \b Point in the 3D space.
+\n There are four algorithms to create a \b Point in the 3D space.
\n Each time the \b Result of the operation will be a GEOM_Object
(vertex).
\n <b>Arguments:</b> Name + 1 reference point + 3 coordinates defining
the position of this point regarding the reference one.

-\n Finally, we can define a point by an \b Edge and a \b Parameter
+\n Thirdly, we can define a point by an \b Edge and a \b Parameter
indicating its position on the Edge, ranging from 0.0 to 1.0. For example, 0.5 means that the
point is located in the middle of the edge.
\n <b>TUI Command:</b> <em>geompy.MakeVertexOnCurve(Edge,Parameter).</em>

+\n Finally, we can define a point by intersection of two \b Lines.
+\n <b>TUI Command:</b> <em>geompy.MakePointOnLinesIntersection(myLine1,myLine2).</em>
+\n <b>Arguments:</b> Name + 2 lines
+

\n To create an extruded shape by \b Revolution you need to define the
source \b Object to rotate, the \b Axis of revolution and the \b Angle by which
the \b Shape has to be rotated around the \b Axis (in degrees).
+\n <b> Both Directions </b> checkbox allows extruding the source
+object both forward and backward.
\n The \b Result of the operation will be a GEOM_Object (edge, face, shell,
solid or compsolid).
