How to Manipulate Faces and Edges in Sketchup 8
Manipulating faces and edges
Now that we understand how to move, rotate, and scale objects we can also use the Move, Rotate, and Scales tools to reshape those objects and we'll do that by moving, rotating, and scaling the faces and edges which comprise those objects. So let's go ahead and take a look at how to do that. So before we do that let's do a quick refresher of faces and edges. Remember that edges are lines. So that's an edge, that's an edge, that's an edge, and those lines define faces.
So this is a face, this is a face, this is a face. So faces are surfaces they're plains and they're defined by edges. So edges create plains which are of faces. So we can manipulate either one of these objects. Let's go ahead and take a look at edges. I'm going to select the very top edge of this roof. So basically the peak of this roof and then all I have to do is move it.
So I'm going to select the Move tool or hit M on the keyboard, and then I can just left click and drag and it should snap to the blue axis, but if not just hold the Up Arrow and that will force it to snap to the blue axis. So now I've just increased the height of my roof simply by moving that edge. If I want I can select multiple edges and move those as well. So I can select this edge, this edge, this edge.
Now I'm holding down the Shift key here. So let's go ahead and select all the edges that are on this roof and Again, if I want to move those as you can see I can move the entire roof. I'm going to go ahead and undo that and now let's take a look at faces. So if I want I can also move faces. So, for example, if I were to select this face here and hit the M key to move I can Again, just move that as well to reshape that or to extend that and actually probably a more practical way to use this will be on this steps.
So go ahead Again, hit Spacebar for select. Select this face on the edge of the steps and then hit the M key to go in to Move mode, and then we can move that and basically make the steps wider. We can do the same for the front of the steps. So I'm going to go ahead select that face and then Again, go into the Move tool or hit the M key, and then I can move those as well. Now if want I can select multiple faces.
So I can go in to Select mode here and Shift+Select both for faces and then go into Move and move both of those, very, very simple. Now we've just been using the Move tool, but we can also use the Rotate and Scale tool as well. But many times Rotate and Scale don't work well on square models like this. But let's just go ahead and take a look at how they work and it may apply differently depending on the model.
So for Rotate just go ahead and just select the face and select the Rotate tool. So all I've to do is select that, Again, drag it out, and then I can rotate. And notice how the model is kind of breaking up for this and this really isn't something that you would want to rotate. So I'm going to go ahead and Undo that and let's go ahead and hit the Spacebar, go to Select and make sure we have that selected again. Let's just go to Scale and see how that works, and Again, this is just to show you that you can scale faces. So I don't think there is particularly a face you want to scale, but it is something we can do.
It just depends on how the model is built. So those are some of the basic tools for manipulating, rotating, moving, and scaling parts of your model.
