[MUSIC] Greetings all, in today's class, we are going to learn the basics of how to draw a beach ball. Here, we will use the Circle tool, the Follow Me tool. And then we will also learn some useful functions that will allow us to draw a sphere easily. So now let's get started with our beach ball module. Now we are going to draw a volleyball, here we will use the Circle tool, and the Follow Me tool, and some other functions. Once we open SketchUp, we can see a toolbar. This is the getting started toolbar, which we have as the default. If we need other tools, we have to click the View in the menu bar. Then click Toolbars and we will see a display of many other tools. Here we select the tools called Views, Styles, and Edit into Toolbar, we will use them later. Once we have completed all this, then we are done with our customization of our toolbar. First, we will show the Circle Tool, the toolbar originally only showed the Rectangle Tool. To see the Circle Tool, we click the drop-down menu and select the Circle Tool. Now we can see a number 24, right bottom of the SketchUp window, which indicates the different numbers of the circle slides. Now from a perspective view, we want to draw a circle which is perpendicular to the z-axis, in other words, the blue axis. We click the left mouse button to place the center of the circle, now we move the cursor along the red axis. This action can avoid some drawing problems, then we click the left mouse button again to finish the circle. Now we select the Top View from the View tools in the toolbar, and then zoom in. If we try to count the slides in the circle, there will be 24 segments in total, which is the number 24 mentioned before. This means the circle has been drawn by SketchUp using a polygon with 24 slides, which is the default resolution of the circle. We can draw the circle again by changing the numbers slide to 50, input 50, enter, this time we will obtain a rounder circle. After knowing how to create a circle in SketchUp, now we can draw a sphere. In SketchUp, we have to make a circle follow another to create us a sphere. So we will draw an arbitrary circle first, then we draw another circle perpendicular to this circle. While we move the cursor around the original circle, we can see our cursor is still showing a blue circle. It means that if we try to draw a circle, it will be drawn in the blue assets. Now, the cursor changed to a red circle, here, we'll click the left mouse button, the center of first circle, and create a new circle. We can give a radial size at our will, here, we just input 2000 mm, or 2 meters, depending on the units. Now we are done drawing two circles perpendicular to each other. At the joint of the two perpendicular circles, we use the Follow Me tool to draw the sphere. Here we select the Follow Me tool, then we click with the left mouse button a surface to follow. And we move the cursor to the line to be followed. The surface will move along the line and create a new surface and complete the sphere. We can also use the key Alter, so, here we can press Alter and select a surface. This command will make parameters of the selected surface become the route to follow automatically. So we click the circle and we will complete the sphere. Here's another way to make a sphere. With the Select tool, we select the edge of the first circle, this will be the path. Then we select the Follow Me tool and then we click the second circle, the result is also a complete sphere. Today, we learned different ways to draw a sphere. We can just use the one we like the most. Let's stop learning, for now, goodbye. [MUSIC]
