Edit Mesh (Extrude)

Tab (Object Mode / Edit Mode)

Let’s move on to Mesh editing.

From now until the end of the first session, let’s master Mesh editing in one go.

You already know how to switch to Edit Mode by pressing Tab, right? When you press Tab, it switches between Object Mode and Edit Mode.

Pressing the Tab is equivalent to choosing it from the dropdown menu here. Using the Tab is more convenient, isn’t it?

Edit Mesh (Extrude)

Once you’re in Edit Mode with the Tab, switch to Face Select mode by pressing the 3 (not the numeric keypad).

After selecting a face with Left Click, press the E.

This immediately enters the Extrude mode, allowing you to extrude the face along the mouse movement.

The above image shows a selected face.

The above image is right after pressing E.

Then, when you move the mouse, the face is extruded, and the side becomes visible. Finally, Left Click at an appropriate location to confirm.

In the case of Extrude, unless specified otherwise, it is extruded in the normal direction.

The normal is the “orientation of the face.” In the face’s coordinates, the normal is the Z-axis.

Therefore, the face is extruded in the direction of the normal, and you see the blue guide lines indicating the normal direction.

Like G, R, S, when using E, you can specify the axis.

For example,

extrudes in the normal direction by a distance of 1.

Moreover, E can be used not only for faces but also for vertices and edges.

For example, you can select a vertex and start shaping freely from there.

Here is a video summarizing the above operations.
