Figure 3.10 - Contextual menu for extrudes

Keep in mind that using the contextual menu is only possible right after

you finish the extrude. It works the same way as with object creation. If

you start another operation in Blender, you will no longer be able to

change settings using that menu.

Tip: The Toolbar options are also available in a floating menu that you

can call using the SHIFT+SPACEBAR keys.

3.3 Loop cut

The Loop cut tool is another useful option to change the shape of an

existing object in Blender. Unlike the extrude tool, you won't create new

geometry with the Loop cut. Instead, you add new edges to an existing

model—the edges loop around your models' shape to give you more

options in modeling.
