Figure 3.14 - Comparing extrudes

As you can see from the comparison, we got a face resulting from our

Extrude Region going inward and keeping both sides. That will require

the artist additional work to "fix" the geometry.

On the other hand, we have the Extrude Manifold managing to push the

face inward and editing both sides simultaneously. That is a huge

timesaver for 3D modeling.

3.4 Creating new edges and faces from

vertices

There are some cases in 3D modeling where you might have two

separate structures that you wish to connect. In Blender, we can connect

objects using the F key when having two vertices or edges selected. The

process is simple and only requires you to have at least two elements

selected.

In Edit Mode, select two vertices in a model and press the F key to

connect them with an edge (Figure 3.15).
