Now let's talk about how to measure and create guides within Google SketchUp. We have two tools in SketchUp. We have the Tape Measure, which is the T shortcut, and we also have the Protractor. Now these are right here as well in your toolbar and they do pretty much is advertised. So the Tape Measure can measure things. So let's say, for example, we wanted to measure this roof. All we would have to do is hit the T shortcut and then just snap to the end point, left-click, drag, and then snap to the other end point. We will see that this roof is 39 feet, 2 15/16 inches long. If I wanted to measure something else, I could very easily click here and measure this roof that is 17 feet and so on.
Now the Protractor works pretty much the same. All I have to do is select the Protractor and then I can just snap it to something and what I can do is I can measure out angles, like this. Now these tools can also be used to create what are called guides and I've just created one here and what guides are, are additional things that you can snap to when drawing. So it allows you to draw irregular shapes. In fact, I am going to ahead and create a new scene here. Let's go ahead and go File > New, No, I don't want to save, and I am going to very quickly draw a box. So I am going to select a rectangle here and just sketch out a quick box. Hit P to pull up that rectangle into a box.
Now let's say we wanted to make a house and we wanted to make a roof with kind of a gabled edge. Well, one of the things you need to do is you need to make sure you draw two lines. I mean I could free-hand that I could draw one line here, one line here, but I don't really know if these angles are the same, if this is centered. I really have no guide in order to draw this. So I am going to undo my way out of this and I am going to use my Protractor tool to measure the exact angle that I want. So what I can do is I can snap this to the corner of this box, drag it out here, and then left-click again and then drag until I get the angle I want. In fact, you can see the angle is right down here in the corner. So let's say I wanted a 45 degree angle, and you have to hit Ctrl to toggle these guidelines.
So make sure you hit Ctrl and then left- click, and you will get a guide. I can do the same on the other side, just left-click, drag to start my angle, left-click again, and then I am going to 45-degree angles. So now that I have that, I can go to my Pencil tool and I have got an exact angle so I can actually draw this at exactly 45 degree. So now I have that first edge of my roof. I can do the exact same thing with the Protractor on the other side. Let's just do this again, left-click to anchor the point, go out to 45, make sure I have blue, which means I am going around the blue axis or the vertical axis. So we go click, click, and then I get it to 45 and I click again. Now I can draw that again. So I know that the angle on both sides of this are the same, and then I can just very quickly sketch a midpoint here.
Now I have all of these guidelines and guidelines can be deleted very easily, all I have to do is just select them and hit the Delete key. So I am going to go ahead and delete all these guidelines, and you can see now that with just using these angles I have what I need to create a very accurate roof. So all I have to do now is hit the Move key, select that edge and just move it vertically, and now I have my roof. Now we can also use the Tape Measure here to create additional guidelines. Let's say we wanted to create a row of windows and we wanted them to be of very specific size. Again, we can use the Tape Measure, just click here, drag, and you see what I am going here is I am dragging a guideline down, and I can say well, I want that two feet below the top of the wall for the top of the window and let's just drag it down a little bit more, and create two guidelines.
I can use these to draw something like a window or something like that, and I will know that the tops of all of my windows will be exactly of the same height. So I can draw a big window surrounded by two smaller windows or whatever I want. Now you can also use these guides to create any sort of angled line, pretty much anything you want. So this is a really good way for drawing things that are, kind of, off of the standard angles. So, for example, if you don't want a thing that snapped to the blue, green, or red axis, you can use the Protractor to create whatever angle you want. Then if you want to do something that's very specific in terms of distance like these windows, you can use the Tape Measure tool. So those are some ways you can use the Tape Measure and the Protractor. So let's go ahead and move on from here.
