Hi everyone. In this video, we're going to take a look at 3D for concept art and for that I'm going to use SketchUp, which is a free 3D software. This is excellent because from the 3D model, we actually have correct proportions and all the depth we need. Also, you can reposition your camera to have more dramatic shots. So there are many advantages of using 3D in your scenes. So let's take a look at how SketchUp works. On the left side of the screen, you have this large toolbox and pretty much everything you need to start modeling in SketchUp you can find here. As pretty much any other software, you can navigate by going to the top menu to find other elements to put on your screen to help you model. So let's take a look at this large tool set which I just showed on the left. If you don't have it on, you go to View, Toolbars, and you click on Large Tool Set. So I'm turning it on and off so you can see that it shows on the left side of your screen. There are other things you can have like the Advanced Camera Tools, the Sandbox. We have the Shadows which are extremely important. We have the Solid Tools and Warehouse. So all this actually I leave checked when I'm working and I can play with a lot of elements when I'm modeling my environments or whatever I need in SketchUp. So let's take a look at the tools. The first set of tools here are the drawing tools. Let's click on the pencil which is the line tool and notice that I have crosshairs; the blue one, the green one and the red one. A way to show this, you go to Window, Preferences. You go to drawing and you click Display Crosshairs and this makes it so much easier for you to line up all your lines with the axis. The red, the blue and the green axis. So let's draw a line on the red axis here and you can see the red line becomes thicker when I'm aligned to that. So here, I don't have any kind of alignment. But if I aligned to one of the axis, the line becomes thicker, and it appears on red axis, on green axis, and so on. So there's actually one thing you need to be aware of, which is, SketchUp only makes faces which are at the same plane. So if I do this it seems like I'm going on the same plane. But when I tried to close the shape you'll see that the shape is all around the planes and not at the same plane. So I need to go back a few steps. So let's Esc to let go off the pencil and Control Z and now I can move my camera to an easier view the map to the correct plane and now I can draw whatever I want. So here I'm just closing a basic rectangle and you see that, whenever we close a shape, we'll have this dark plane. Which is pretty much the inside of whatever solid you're going to make. So if we use the eraser. You'll see that I cannot erase planes but I can erase the edges, only edges. So if I grow my eraser on top of the edges, you'll see that I erase the edges and I no longer have a plane. So let's create a triangle here. Again, if all the edges are coplanar, I can create a face. Again, I cannot erase a face, just edges. So be aware of that whenever you are using your tools. So let's go to the free hand tool. The free-hand actually pretty much as the name says, allows you to create any kind of shape. So whenever I finish, it will not close to a face unless I move to the origin point and then I'll have a face, and you see that this shape can be anything I want. But usually it's a little bit wonky because it's free hand so it's better to rely on more regular shapes. Let's see now the rectangles, circles, and all the other ways to create geometry in SketchUp. So let's begin with the rectangle. So to create a rectangle, you just click, release the button, drag your mouse to wherever you want and then click the button again, and when you do that, you're going to have your rectangle. Simple as that. You don't need to hold your button when you are moving the mouse. Just click, release and click again to close the shape. So you can create as many shapes as you want as long as they don't overlap because if shapes overlap, they're going to stick together. So let's try to create a circle now. So I can click, release the button and drag. So let's do it again here and here and it's the same procedure. Just click, release the mouse button and click again, whenever you have the radius you want. Same thing with polygons. You can do this, just by clicking releasing and clicking again. There are some arc tools. So this one is the two-point arc. So I can click on wherever I want on my rectangle and then I define the height of my arc and in this case I chose to have circle and SketchUp has a pretty good inference system that tells you when you have a perfect rectangle with perfect proportions. When you have a square, when you have half circle. So this is pretty useful. So this is protractor rectangle so I can create rectangles by using slanted angle. So this is also good and, and notice that SketchUp was originally intended for Architecture. But obviously, we can also build like props and weapons, vehicles, whatever you want. But again originally was intended for architecture. So all the tools here they are really good for building environments and, and buildings and things of the sort. So there are all this arc and Pi tools. So you can create different sorts of curves. This is the Pi tool so you click. You choose the angle you want and when you click again, it closes the shape to you. It's a little bit different than the previous one. The three-point arc on which you click and you just drag. This is kind of weird to create an arc with but yeah, and you have an arc which is not actually a face, it's just like an open arc. So all these tools here are drawing tools. Just have this in mind when you are creating your shapes because they make your life much easier if you know how to use them, and if you know how to align them with the axis on SketchUp. So another interesting thing on SketchUp is the zoom system which is pretty much contextual. So if I'm pointing my mouse here, I'm going to zoom in and out from this point. So if I move my mouse to the figure, I zoom in and out from the figure. Also, if I hit H on my keyboard, I have the hand which is the pen tool in SketchUp. All this is actually to enable you to navigate easier throughout SketchUp. So H for the hand tool which is the pen and remember where you place your mouse is the point which you are going to zoom in and out. Now, the selection system. If I drag my mouse from left to right, I only select entire objects like this. So if the entire object is inside my selected it will be selected. Whatever is not fully inside the selection from left to right, will not be selected. However, if I select from right to left, whatever the bounding box is touching will be entirely selected. So if I click here and just drag from right to left, you can see that I'm going to have all these lines which the bounding box is touching selected. So these are two nice ways to make selection and it will save you a lot of time when you need to select specific parts on your 3D model.
