To generate a \b Pipe in the <b>Main Menu</b> select <b>New Entity - > Generation - > Extrusion along a path</b>
-\n To create an extruded \b Pipe shape, you need to define the <b>Base
+\n Firstly, to create an extruded \b Pipe shape, you can define the <b>Base
Object</b> (vertex, edge, planar wire, face or shell), which will be extruded
and the <b>Path Object</b> (edge or wire) along which the <b>Base
-Object</b> will be extruded.
+Object</b> will be extruded.<br>
+It is possible to select in GUI several Base Objects to make several pipes (using Shift button).
+\n In this mode the default pipe generation algorithm is used. The pipe
+is created so that the <b>angle between the normal vector</b> to
+the base shape <b>and the tangent to the path</b> wire remains constant at any point of the
+given path.
+\n <b>Select unpublished edges</b> checkbox - if checked, allows to select an edge of any other shape as the path object.
\n The \b Result of the operation will be a GEOM_Object (edge, face, shell,
solid or compsolid).
\n <b>Arguments:</b> Name + 1 shape (vertex, edge, planar wire, face or
shell) serving as base object + 1 shape (edge or wire) for
definition of the path.

+\n Secondly, you can define the <b>Base
+Object</b> (edge, planar wire or face), which will be extruded,
+the <b>Path Object</b> (edge or wire) along which the <b>Base
+Object</b> will be extruded and the <b>BiNormal Vector</b> (edge or
+wire).
+
+\n In contrast to the default mode, in this mode the pipe is generated
+to preserve the constant <b>angle between the normal vector</b> to the base
+shape <b>and the BiNormal vector</b> given as the third argument.
+\n <b>Select unpublished edges</b> checkbox - if checked, allows to select an edge of any other shape as the path object.
+\n The \b Result of the operation will be a GEOM_Object (edge, face, shell,
+solid or compsolid).
+
+\n <b>TUI Command:</b> <em>geompy.MakePipeBiNormalAlongVector(baseShape, pathShape, binormalShape)</em>
+\n <b>Arguments:</b> Name + 1 shape (edge, planar wire or face)
+serving as base object + 1 shape (edge or wire) for
+definition of the path + 1 shape (edge or wire) to set a fixed
+BiNormal direction to perform the extrusion.

+
+\n Thirdly, it is possible to additionally select profiles of the pipe object to be built. For this, you can define the following parameters:
+- <b>Base Object</b> or a list of objects (edges, planar wires, faces or shells), which will be extruded;
+- <b>Locations</b> - a vertex or a list of vertices that specify the locations of extruded <b>Base Objects</b> on the resulting <b>Path Object</b>. The number of Base Objects should be equal to the number of <b>Locations</b>.
+- <b>Path Object</b> (edge or wire), along which the <b>Base Object</b> will be extruded.
+
+Additional controls:
+- If <b>With contact</b> is checked, the section is translated in contact with the spine.
+- If <b>With correction</b> is checked, the section is rotated to be orthogonal to the spine
+tangent in the corresponding point.
+
+\n The \b Result of the operation will be a shell or a solid.
+
+\n <b>TUI Command:</b> <em>geompy.MakePipeWithDifferentSections(baseShape, locations, pathShape, withContact, withCorrection)</em>
+\n <b>Arguments:</b> Name + list of shapes (edges, planar wires, faces or shells) serving as base object +
+list of locations (vertices) on the path corresponding specified list of the shapes +
+1 shape (edge or wire) for definition of the path +
+2 Boolean parameters (withContact, withCorrection).
