* **Select the whole mesh, sub-mesh or group** activating this check-box.
#. There are two optional parameters, which can be very useful:
-#. If the path of extrusion is curvilinear, at each iteration the extruded elements are rotated to keep its initial angularity to the curve. By default, the **Base Point** around which the elements are rotated is the mass center of the elements (note that it can differ from the gravity center computed by *Geometry* module for the underlying shape), however, you can specify any point as the **Base Point** and the elements will be rotated with respect to this point. Note that only the displacement of the **Base Point** exactly equals to the path, and all other extruded elements simply keep their position relatively to the **Base Point** at each iteration.
-
-#. The elements can also be rotated around the path to get the resulting mesh in a helical fashion. You can set the values of angles at the right, add them to the list of angles at the left by pressing the **"Add"** button and remove them from the list by pressing the **"Remove"** button.

- **Linear variation of the 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 )*.
