Like with our 2d objects, if you want to scale them uniformly, it’s best to use the corner grips.
You can click and drag any of these grips to resize your object. These grips work exactly like the ones we talked about in the two dimensional scaling tutorial previously. When you do this, you’ll notice a bunch of little green boxes show up on your cube. Now, just like with our two dimensional objects, we’re going to activate the scale tool by clicking on the scale tool icon above or just pressing the “s” key on your keyboard. If you’ve done this correctly, all the bounding edges and faces in your model should be shaded blue, like the image below. Select the whole cube by dragging a select box all the way around it. Let’s start by selecting our entire cube. This is useful, but it can also deform your shape, so you have to be careful. You can select any of the individual faces on your cube and scale them without scaling your entire cube. However, with a 3D object, this isn’t the case anymore. When we were working with two dimensional shapes, it didn’t really matter how you selected your object because you were only dealing with a single face. I want to start off by talking about how you select your object when working with 3D shapes. Once you’ve done that, you should have a shape like the following image below.
You can draw the box using the rectangle tool, and then use the push-pull tool to extrude it into a 3d shape. Let’s start off by drawing a box, then extruding it into a cube.
Look up at the top of your screen for a little icon that looks like a brown box inside a red box with a red arrow coming out of the corner.
First, let’s take a second and review where the scale tool is located. In this tutorial, I want to talk a little bit about using the scale tool to work with three dimensional objects. In my last tutorial, I talked about using the scale tool in SketchUp to modify your two dimensional shapes by resizing, reshaping, or mirroring your shapes.
