In this course, author George Maestri explains how to model and render 3D objects and scenes using SketchUp 8. The course covers the fundamentals of the application, from navigating the user interface, manipulating objects, and building basic shapes to importing objects from Google Earth, animating a scene, and modeling organic terrain using the Sandbox tools. The course also explores SketchUp Pro features, which are available as an upgrade. These include tools for creating dynamic components and adding interactivity, as well as sophisticated importing and exporting options for working with outside applications.
Now let's go ahead and start creating objects from scratch within SketchUp. I'm going to start with the Line tool. But before we do that let's go ahead and clear out our scene. I'm going to do File>New, and then I'm going to hit my Spacebar to activate my Select tool, select the person in this scene and hit the Delete key. Now that I have a clear scene let's go ahead and start drawing. The Line tool can be found here under Draw>Line. You also remember the L key for line is a great hotkey to know, or you can activate it here from the toolbar.
Now when you activate the Line tool, you get a little pencil icon here, and all you have to do is place that pencil where you want, left-click, and start dragging. You'll notice how you can just start drawing. So I can left-click again, lay down another line, left-click, left-click, and then If I want I can end it by just placing this over that original endpoint , and you'll see that it actually creates a plane or a face in SketchUp lingo.
That's pretty much the basic process. You just-left click and lay down your lines. Now I'm going to go ahead and go to my Select tool, rubber band select all of this, and delete it. Now one of the things you have to be aware of with that Line tool is that we are drawing in a 3D space. So if I were to draw something like this, it might be a really wonderful shape, but it's only a wonderful shape from this angle.
If I move my camera you'll realize that, well, it's not exactly how I pictured it on the screen. So sometimes when you draw in 3D you might not get the proper perspective you need to actually place the points where you want. That's where snapping and inferences come in very handy. So let me show you about those. Again, I'm going to activate the Select tool and then just select everything and delete it. So let's go ahead and see how snapping works.
I'm going to go back to the Line tool and I'm going to Again, lay down my first point, but now let's take a look at how snapping works in inferencing. This is very similar to how the Move tool works. So as I come over to the Green Axis, notice how it's snaps and that line becomes green. So if I'm able to draw on this axis, I will get something that's parallel. Now every axis will snap.
So I can snap to the Red Axis, and if I go up I can snap to the Blue Axis, and this can really help you draw things accurately. So I'm going to go ahead and snap this to the Green Axis and lay down my point. So now I have a line that's parallel to that Green Axis. If I wanted to, I could draw and snap to another axis. So if I snap to the Red Axis and lay down that point you'll see that I have a right angle, because those two axes are add a right angle to each other.
And if I want I can keep going. So I can snap to the Green Axis again, and notice how as I come close to my original point I get another type of snap and that's this little dotted line. In this case it's a dotted red line and that tells me that I'm exactly across from this point. So this point here when I get to that it actually snaps and that's what's called an inference.
So what SketchUp is doing is it's trying to inferior what I'm doing. So it says, hey, here is a point. Maybe you want to snap to this so you can create a rectangle. So if I snap to this then I know I'm directly across from this other point and when I draw that last line, I do get the rectangle. So let's take a look at that. So that's pretty cool. We don't have to snap on a flat plane, we can also go in 3D, for example, if I were to click on this endpoint and go vertical I could draw a vertical line that snapped to the Blue Axis.
Then I can go over on the Green Axis, and Again, if you'll notice I'm snapping, I'm inferring that it's right here, and then draw down again. So what I've done is I've drawn a rectangle and now I have objects that are in 3D. I have two planes at a wide angle to each other. And if I want I can just keep going. So I can snap to this endpoint, draw over in red, and notice how I'll get this inference here. So I'm going to lay down my second point here by left-clicking and then just snap to blue.
Now I am going to have the beginnings of a box. So let's go ahead and finish that. I'm going to select here, draw, wait for the inference here, and so as you can see we're starting a box. So all I have to do now is just connect this point with this point. So I think this is really neat, because what you can do is you can use one tool and just by drawing lines we've actually sketched out a complete object in 3D. So this is really a very powerful feature of SketchUp.
It's a simple tool, but you can do a lot with it.
