Join Paul J. Smith for an in-depth discussion in this video Groups, components, and the Outliner, part of SketchUp for Architecture: Fundamentals.
Now there's a lot that's been written about groups and components. And I don't want to necessarily go over the old grand that you can easily discover elsewhere. But I do want to show you a couple of things. If you're an absolute newbie to this program, then there'll be a couple of things here you might find interesting. But it's more about the Outliner that we're going to concentrate on in this short video. But the main differences between the groups and components, now I've got three sets of identical looking boxes.
These are the components. These are the groups. And these are individual bits of geometry all lined up. Now all they are is a container, which double click to edit and then I've got access to the various bits of geometry inside. But it does mean that if I wanted to move this object onto this one. Instead of just picking it by clicking on it once, if I just clicked on this once, then I'm just going to pick up a face. So, I need to marquee select to select the whole thing.
So, that's already a problem. And I move that onto that and then I want to move it back and think, oh no, I didn't want it there. Then all of a sudden this sort of thing happens on the geometry sticks. So, not very efficient at all. However, using a group or a component, you can just pick it up and move it. And if you decide that's not where you wanted to put it, then you can position it back where it was. Another thing you can do with either a group or component, is to use the move tool. And this will allow you to rotate the object around its center.
So if you hover over one of these crosses, then that allows you to rotate this object. And it'll work in all sorts of different planes. And the final obvious difference between group and a component if I select both of these, is that if I was to edit the component, then all instances of that component get updated. If I was to edit the group, then it's just the group that gets updated. So this is the main source of differences between groups and components.
Now, there are some other subtle things that you might not be aware of. I've created three different files. All with the same geometry in. But one is all components. And that's 85k. One is all groups and that's a larger file size, 108. And one is neither groups nor components and that's just basic raw geometry and that's turned out to be 101. So the one that's made up of just groups is the biggest file size. So just be careful that groups do increase the file size.
Components significantly reduce the file size. Now, if you had a massive drawing with loads and loads of bits of geometry, then you can see there'd be significant savings by using components. So that's another thing that you might be interested in. Finally, we'll just look at Window and Outliner. And there are some really, really cool things you can do with the Outliner tool. And we'll highlight those as we go along. But some of the things that you can do is identify the groups or the components.
You see that this lower geometry isn't picked up in this. But these are the components and these are the groups. So if I wanted to select the green component and ctrl + click the yellow component, then I can pick those up. I mean, I could do it just as easy there. But if I wanted to hide this piece of geometry, I'd right click and hide on that. And then you see it's just grayed out there. If I wanted to bring it back, then unhide through the Outliner. That's a very useful tool. To create groups within groups, then I could select these two things and right click and make a group of that.
Now that would basically put these two elements on the same footing. It gives me the option, opportunity to rotate these around. That was an accident really. But if I double-click or select the object, see the way their stacked? They're both inline on this little tree. And they both have the same sort of hierarchy. So to edit the teal one, I double-click, and that allows me to edit this one. To edit the green one, double-click on the green one.
And I can edit the green one. The other thing you could do is, if I wanted to move the pink one into the yellow one. I just take the pink one and drag it into the other one. Then there's a difference in the hierarchy. So whilst these two are now grouped together, they're not under a group. Pink one is now nested inside the yellow box. So, to edit the pink one, and not go straight into editing this, so accessing the pink group will ultimately make the yellow group able to be edited.
If I want to take that out of this yellow group, I have to move the pink one right up to the top, and then that becomes separate entity again. So they're both two objects. These, however, are still the same. And to get these back to their original geometry, I'd have to right click and explode that. And that just gives me the two levels again of group. So we will be covering a lot more about groups and components as we move through the various tutorials. But that was just a brief overview of the main differences between groups and components.
And looking at some the other elements as well that you might not have been aware of.
