In this lecture, we'll be learning about extruding objects to create more geometry.

So here's what we got up to last time, and let's start thinking about the fit.

Now I can't actually select my foot.

Have a quick think why that is.

Well, it's because I'm in edit mode for the lower leg object, so I need to go into object mode with

tab and then select the foot and then go into edit mode with Tab.

And remember Tab is the shortcut to get to edit mode and object mode just here.

So let's go to front view and we can see that the foot's relatively OK from front view.

It might need a bit of adapting, but we need more editing from side view.

So let's go to side view with three or more numpad now we could add a loop cut down here and then move

these two upwards.

But I want to show you a different tool for creating new geometries, so new faces, vertices and edges.

So I'm going to move this into position around this section here.

So a box like these sheets grab and move those into position these ones to this one towards the back

and this one towards the back as well.

Now you might notice I've got this overlapping very slightly and that's actually OK to have geometry

overlapping like this.

Generally speaking, later on, you'll probably want all these things to be one object, but it is common

practice to have models overlap like this, especially with low poly models.

It's not always optimal, but it is OK.

So let's go back to side view, and what I want to do is create a new section that comes out this way.

Well, I've got these four vertices here that I want to extend out, and actually, that's the same

if I go to face mode as just selecting this one face.

So I mean face mode and I want to extend this out.

What we can do is press e to extrude.

So is the shortcut key for that, and it creates a new mesh that we can kind of bring out like this.

So I'll bring it out just a touch and then go to side to you and then actually move it into position.

So then why and move it into a position like this?

Then I can go to Vertex mode.

Incidentally, you can press one on your keyboard and that's one, two and three for Vertex Edge and

faces the Vertex mode with one box.

Select these top ones teeth, grab in the Z and move it downwards.

So easy to extrude is the command to pull out geometry like this, and you've got that as well over

here and you can see the shortcut key is just there.

So take a moment to catch up with me and do that first extrusion.

Let's come right in front of you now.

Now I want to select these vertices here and pull them outwards, but I've got the back two vertices

here as well, and I only want these ones.

So just be aware of that when you're modeling things in front view and side view and block selecting

objects.

Now what I could do is go to front view and turn off x ray mode and then select the front two and it

won't select the back.

So that's why it can be helpful to go back into solid mode when you're in one view just to select the

front vertices.

Now let's go to front view with one G to grab in the X and pull it out to somewhere around there.

And we've got the beginnings of our foot.

Now, the toes of my model are a separate object in the drawing, but I'd like to give you the challenge

of creating the toes of this foot by using the extrusion command.

So pause the video and have a go at that.

OK, so hopefully found that, OK, the first thing to do is either select all four of these vertices

because you can extrude all those four vertices out as well, but I'll undo that.

It's much easier to press three to get face mode and select just that face.

Generally speaking, you'll be just extruding faces rather than anything else.

So with that selected now, I can go to side view with three of my numpad e to extrude and pull that

out that way to somewhere around there.

I could press one to go to Vertex Mode up to x ray so I can select the one in the background as well.

Box Select those g to grab and pull it down with very slightly.

I turn off X Remote so we can see a completed leg there.

Let's get the front view.

Make sure we're lined up correctly.

These top vertices look like they need a bit of work, so let's go into X-ray mode again and just move

those across.

So grab in the X this time, and if we wanted a bit of distance between them, we can select them g

to grab in the Z.

And it won't necessarily line up with the Y, but it will line up with the X and I think I'll move these

ones in as well.

So just grab in the X and move those across back to solid mode.

So turn off x ray and see what we've got.

And we've got this sort of interesting looking leg, so pulls the video and make sure you're caught

up with me.

Now, I think our ecosphere here could do with being a bit bigger to kind of overlap these areas.

So of course, VIDEO And have a go at making your, I guess, fair just a bit bigger.

OK, the reason I wanted you to do that was get used to the command of Pressing tab to go back into

object mode, then selecting your new object.

And if you need to edit it, of course you go into edit mode.

But we don't need to here so we can stay in object mode and just resize it with S2 scale.

Let's go to front view and see how that's looking.

We might want more of an oval shape so as to scale in the x axis, and it looks a little bit more like

a neighbor.

I think as well, if I get the same view, we can afford to bring that forward slightly to somewhere

around there.

OK, so we've managed to create our leg.

So that concludes this lecture.

Make sure you've saved your work ready for next time.
