[MUSIC] Greetings to all, in today's class we are going to learn how to use the push and pull tool to cut or add balance to our already created objects. We will also start using the guidelines to help the drawing process. Now, let's get started. We can see here is a structure. It is made of 10 by 10 by 10 cubic meters cube, which has 4 by 4 square meters hole in the middle of each face. And each hole has steps of 3 meters. Now we are going to use the tape measure tool and the pull and push tool to draw the structure. The tape measure tool is one of very helpful tools provided by SketchUp. Not only can it be used for measurements, but it can produce guidelines. First, we draw a cube with side length of 10 meters. Now we select the tape measure tool and click on the sideline. When we drag the mouse to the right, we can see there appears a guideline parallel to the sideline. In the same time, we make sure point's color is blue which means the point is on the face. Then we input 3 into measurement box and press Enter. Now we get a guideline with an offset of 3 meters from the sight line. By following the steps mentioned before, we will get four guidelines relative to each side of the face. Next, we select rectangle tool and draw on the intersection of of the guidelines. Therefore, we get 4 by 4 square meters hole in the middle of one face. We should repeat this procedure and a door on each face of the cube. We should stick to the principles of how to use the tape measure tool. Do not worry about guidelines messing up our view area, it is temporary function. If we are done with them, we could hover the mouse to the guideline we want to delete and click the right mouse button and hit erase. Furthermore, if we want to erase all the guidelines, we simply select edit and hit delete guides. There, we get a clean view area. Now, to use pull and push tool to create holes. We select a tool and click on the plane that we want to create the hole. Pull and push tool can create heights, also depths too. Here we can push the selected plane to the other side of the face. This action finishes when we click the left most button from these. We obtain a whole that go through the entire cube, which will follow dimension step over each phase. We click on the pen where we want to place our hole and then we push this pen to the bottom. This same applies to the other faces. Notice that when pushing a surface before ending the execution of pull and push tool, the mouse should be hovered on the outer side of the face. Otherwise, the hole will not be dug through the two faces, especially function of join guideline. In today's class, we finished the basic SketchUp functions for handling objects with plane surfaces in our magic cube module. Let's take a rest and I'll see you in the next module. Good bye. [MUSIC]
