5 \n To generate an \b Extrusion on an object in the <b>Main Menu</b>

16 \n There are 3 algorithms for creation of an \b Extrusion (Prism).
17 \n The \b Result of the operation will be a GEOM_Object (edge, face, shell
20 \n Firstly, you can define the <b>Base Shape</b> (a basis of the
21 extrusion), the \b Vector (a direction of the extrusion) and the \b
22 Height of extrusion. Optionally you can define the <b>Scale Factor</b> to
23 build extrusion with scaled opposite base. Scaling is possible only
25 <br>It is possible to select in GUI several Base Shapes to make
26 several extrusions (using Shift button).
27 \n The \b Result of the operation will be a GEOM_Object (edge, face,
28 shell, solid or compsolid).
29 \n <b> Both Directions </b> checkbox allows extruding the source
30 object both forward and backward. With this option scaling is not possible.
31 \n <b>TUI Command:</b> <em>geompy.MakePrismVecH(Base, Vector, Height, theScaleFactor = -1.0)</em>
32 \n <b>Arguments:</b> Name + one or several shapes (vertex, edge, planar wire, face or
33 shell) serving as base objects + 1 vector (for direction of the
34 extrusion) + 1 value (dimension) + 1 optional value (scale factor for

40 \n Secondly, you can define the \b Extrusion by the <b>Base Shape(s)</b>
41 and the \b Start and <b>End Point</b> of the \b Vector (in this way
42 you don't need to create it in advance). Optionally you can define the
43 <b>Scale Factor</b> to build extrusion with scaled opposite
44 base. Scaling is possible only with 1D and 2D bases.
45 \n <b> Both Directions </b> checkbox allows extruding the source
46 object both forward and backward. With this option scaling is not possible.
47 \n <b>TUI Command:</b> <em>geompy.MakePrism(Base, Point1, Point2, theScaleFactor = -1.0)</em>
48 \n <b>Arguments:</b> Name + one or several shapes (vertex, edge, planar wire, face or
49 shell) serving as base objects + 2 vertices + 1 optional value (scale factor for

54 \n Finally, you can define the \b Extrusion by the <b>Base Shape(s)</b>
55 and the <b>DX, DY, DZ</b> Vector. Optionally you can define the
56 <b>Scale Factor</b> to build extrusion with scaled opposite
57 base. Scaling is possible only with 1D and 2D bases.\n
58 <b>Both Directions</b> checkbox allows extruding the
59 source objects both forward and backward. With this option scaling is not possible.
60 \n <b>TUI Command:</b> <em>geompy.MakePrismDXDYDZ(Base, dx, dy, dz, theScaleFactor = -1.0)</em>
61 \n <b>Arguments:</b> Name + one or several shapes (vertex, edge, planar wire, face or
62 shell) serving as base objects + 3 axis directions + 1 optional value (scale factor for

67 <b> Add thickness </b>
69 \n For all three ways of creation of a prism it is possible to add a thickness
70 to the created prism (only when extruding an edge or wire).

74 You can choose the \b Thickness and the direction of the thickening. By default the material is added on
75 the outside of the generated pipe.

79 \n <b>TUI Command:</b> <em>geompy.Thicken(Shape, Thickness)</em>
80 \n <b>Arguments:</b> A shape (shell or face only) and a thickness
