+\n Finally, you can define the \b Extrusion by the <b>Base Shape(s)</b>
+and the <b>DX, DY, DZ</b> Vector. 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.\n
+<b>Both Directions</b> checkbox allows extruding the
+source objects both forward and backward. With this option scaling is not possible.
+\n <b>TUI Command:</b> <em>geompy.MakePrismDXDYDZ(Base, dx, dy, dz, theScaleFactor = -1.0)</em>
+\n <b>Arguments:</b> Name + one or several shapes (vertex, edge, planar wire, face or
+shell) serving as base objects + 3 axis directions + 1 optional value (scale factor for
+the opposite base).
