- * If you activate **Generate Groups** check-box, the **result elements** created from **selected elements** contained in groups will be included into new groups named by pattern "<old group name>_extruded" and "<old group name>_top". For example if a selected quadrangle is included in *g_Faces* group (see figures below) then result hexahedra will be included in *g_Faces_extruded* group and a quadrangle created at the "top" of extruded mesh will be included in *g_Faces_top group*.
+ * The elements can also be rotated around the **Base point** to get the resulting mesh in a helical fashion. You can set the values of **Rotation angles** to the list by pressing the *"Add"* button |add| and remove them from the list by pressing the *"Remove"* button |rm|.
+
+ **Linear variation of angles** option allows defining the angle of gradual rotation for the whole path. At each step the elements will be rotated by *( angle / nb. of steps )*.
