+\n There are 3 algorithms for creation of an \b Extrusion (Prism).
\n The \b Result of the operation will be a GEOM_Object (edge, face, shell
solid or compsolid).
\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.
+Height of extrusion. Optionally you can define the <b>Scale Factor</b> to
+build extrusion with scaled opposite base. Scaling is possible only
+with 1D and 2D bases.
+<br>It is possible to select in GUI several Base Shapes to make
+several extrusions (using Shift button).
