In this course, author George Maestri explains how to model and render 3D objects and scenes using Google 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.
There are two additional ways to manipulate objects within SketchUp and that's by rotating and scaling those objects. We can find the Rotate and Scale tool under tools>Rotate, and Scale, and the hotkeys are Q and S and there is also a Rotate here, and a Scale here in the toolbox. So we have Move, Rotate, and Scale. So let's go ahead and play with Rotate first. So I'm just going to go ahead and select Rotate, and let's just go ahead and just move this around and notice how when you select the Rotate tool, this little protractor kind of device comes up, and this really just tells us how we're going to rotate it.
So, for example, if I go over to this chair, notice how it snaps to the surface. So if I'm on the side of the chair, it's going to rotate around the red axis. If I go to say the front of the chair, it will rotate around the green axis, because that axis is perpendicular to that face. If I find something that's on the top, it'll rotate around the vertical axis. So all we need to do is select the axis that we want and this is going to require two clicks.
So what I do is I get my Protractor, snap to the axis that I want, and then click and let go and what this does is it just allows you to pull out this line, and then when you click the second time, that's when you rotate. So basically what you're doing is you're kind of creating an arc. Also notice that as you rotate, it will snap to 90 and 180. So if I wanted to rotate this 90 degrees you can get the snap to 90.
If you want to rotate a specific angle, you can always type that in. Notice how here on the bottom it's actually telling me the angle in this little box in the bottom-right corner. So if I want, let's say I wanted to rotate it 45, all I have to do is type-in the number 45 and hit Enter, and it will rotate. So again, I can select this, left-click, drag out a line and then rotate again.
If I want, I can type-in a number such as 45. So let's go ahead and just move that back. I am just going to go ahead and notice how it will snap to 90, so I'm going to go ahead and snap it back. Just like with the Move tool you can use the Rotate tool as a Copy tool. So, for example, if I select this couch, and activate the Rotate tool, I can copy this couch. So all I have to do is hold down the Ctrl or the Option key depending on whether you're on PC or Mac, and then just hold down the Ctrl key.
As you hold down the Ctrl key, notice how you have the Plus sign here and then left-click and drag and now I can copy that couch. So if I rotate it around 90 degrees and then hit the Move tool, I can create a second couch. So as you can see copying while rotating can also be very advantageous. You can, for example, rotate something around; you can also create arrays of things. So if you wanted something to be in like a fan shape or something, you can just make successive copies of it.
Now, the next tool that we want to use is the Scale tool. So I'm just going to go ahead and select this couch, and let's go ahead and scale it. We can use the Scale tool here, or we can go into tools, and just hit the S key for Scale. So I'm going to go ahead and activate the Scale, and notice how when you activate this tool, all of these little boxes come up. So we have a bounding box around the object, and then all of these little box shaped handles, these will tell you how it's going to scale.
So if you select ones that are in the middle of an edge, you can scale diagonally around the object, or If you select the corners, this is uniform scale. So this is just making it bigger and smaller, it's not really stretching it. And if I wanted to, I could stretch it by doing this, and so on. If I want to scale uniformly no matter what, I can always hold down the Shift key. In fact, if you look here along the bottom here, it says Ctrl will always scale around center, or Option on the Mac, and Shift will toggle uniform.
So if I hold down the Shift key it will scale uniformly. If I let up on the Shift key, it'll squash and stretch, hold down the Shift key, it will scale uniformly. Now if I hold down the Ctrl, or the Option key, it will scale around the center. Now the reason you may want to do this is because if you scale uniformly around the opposite point, it will scale towards that corner. But if I scale while holding down the Ctrl or the Option key, it will scale around the middle of the object.
So those are the basics of the Rotate and Scale tool, and I'm sure you're going to be using these a lot as you work with SketchUp.
