5 \n Revolution is a type of surface meshing by generation from
6 discretized lines. It is used to build mesh elements of plus one
7 dimension than the swept ones. Each swept 1D element produces one or
8 more quadrangles (or triangles if one node of a rotated element lays
9 on the revolution axis).
11 <em>To apply revolution:</em>
13 <li>From the \b Modification menu choose the \b Revolution item or click
14 <em>"Revolution"</em> button in the toolbar.

27 In this dialog box you should specify:
29 <li>the type of elements which will be extruded (1D or 2D),</li>
30 <li>specify the IDs of the elements which will be revolved by
31 selecting them in the 3D viewer or select the whole mesh or
33 <li>specify the axis (point and vector) around which the elements will
35 <li>angle of rotation and number of steps,</li>
36 <ul> <li> Angle by Step - the elements are extruded by the specified angle at each step (i.e. for Angle=30 and Number of Steps=2, the elements will be extruded
37 by 30 degrees twice for a total of 30*2=60)</li>
39 \image html revolutionsn2.png
41 <li> Total Angle - the elements are extruded by the specified angle only once and the number of steps defines the number of iterations
42 (i.e.for Angle=30 and Number of Steps=2, the elements will be extruded by 30/2=15 degrees twice for a total of 30). </li>

50 <li> <b>Preview</b> checkbox allows showing the results of parameter-setting in the viewer </li>
51 <li> <b>Generate Groups</b> checkbox allows copying the groups of
52 elements of the source mesh to the newly created one. </li>
