\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 in such a way that the <b>angle between the normal vector</b> to
-the base shape <b>and the tangent to the path</b> wire at any point of the
-given path <b>is kept constant</b>.
-\n Check Box <b>Select unpublished edges</b> - if checked, allows to select an edge of any other shape as the path object.
+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Select unpublished edges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>Vector</b> (edge or wire).
+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
-in such a way that the <b>angle between the normal vector</b> to the base
-shape <b>and the BiNormal vector</b> given as the third argument <b>is kept
-constant</b>.
-\n Check Box <b>Select unpublished edges</b> - if checked, allows to select an edge of any other shape as the path object.
+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Select unpublished edges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).
