Recall that these tools can be activated as follows:

You can also activate these tools using the keyboard short cuts, compass or the context sensitive toolbar.

1. Create a SDS cube and switch to the 'Edit/Face' mode.

2. Select the left and right side faces. Now you can see their face normal handles.

3. Subdivide the selected faces: hold down the Ctrl key and drag the left normal end handle towards the face center.

4. Select the topmost left and right faces and drag the 'move on normal' handle while holding down the Ctrl key to extrude. Do this twice.

5. Now, switch to the top view and multi-select the right end faces. Stretch them wider (use the Transformation/Extend tool) to form a tail. Then use the Extend tool again to make the opposite end, the head, narrower.

6. Subdivide the end face of the head so that we can extrude a beak out of it.

7. Extrude two end faces a couple of times and scale them to look like a beak.

8. Subdivide the bottom face of the bird. Subdivide the created middle bottom face again. Scale a suitable pair of the bottom faces smaller so that they can be used for extruding legs out of the body.

9. Now extrude the selected faces a couple of times to get the legs extruded.

10. Subdivide the end faces of the legs. Then select the four outermost end faces in both legs for toe extrusion.

Subdivide the end faces of the legs. Four outermost faces selected.

11. This time start the 'Extrude' tool from the control bar. Set the Region option to Separately and extrude the toes.

12. Modify the extruded toe faces making three toes to point forward and one toe to point backwards.

The next task is to extrude wings out of the side faces of the body to get our bird completed. However, this would just be repeating the steps described above. Therefore, we complete this example here.
