 Here we are in part 7 then and that means it's time to show you Duplicating and also introduce you to the rotate tool. So we have our original wall here We need to make sure it's selected and we're going to duplicate this So the way to do this from the menus is if we go to edit up here And then we just go about just over halfway down You'll see that duplicate there is listed and it shows you the keyboard shortcut for this is control and D Which is what I'll be using moving forward because control and D is much quicker than going into their menus and When we duplicate you actually in the viewport won't see That the duplicate is there what you will see is that the name here changes So when it duplicates something you'll have the duplicate selected. So let's click on duplicate them So you see the viewport doesn't really look any different but now instead of wall we have wall one selected, which is good So to separate these two because they're currently sitting right on top of each other I'm going to put my move tool on and I'll just bring this in To the center of the room so that I can now see that I've got my two copies I'm happy to keep the name at wall one because I know it's a wall and it's a copy of the original So that's fine, but the direction this wall is facing is not particularly useful We need it to rotate by 90 degrees The appropriate tool for this is of course the rotate tool which is the final of the three main tools over here So we'll turn that on from here. You can of course press the e key, which is the keyboard shortcut Now that I've clicked on each of these I will probably be sticking to the keyboard shortcuts from now on So here's what we need to do We're going to rotate this round either 90 degrees this way or you can go minus 90. It doesn't really matter And if you have a look over here as you're rotating you'll see when you're getting close So we can go there, but the problem is it's going to be almost impossible to get it to exactly 90 degrees So you can just type that number in and press enter and That will mean that that is now rotated Exactly 90 degrees, but I want to undo that and show you another way What you can also do whilst rotating is hold the J key on the keyboard And if I rotate now you'll see that it snaps to 15 degree increments This can be really useful when you just kind of working in a freeform way in the viewport So I'm just going to rotate that round and that's 90 degrees exactly the final thing to do in this step It's just to get it lined up so this time what I'm going to do is Just hold X on my keyboard And you'll see that that shows that this snapping up here grid snapping is going to happen And if I move side to side what I'm doing is I'm snapping it to the center of the grid and Because this is now lined up here I'm happy that that position is in the center of the grid and you can see that that makes sense and Then I'll just kind of freehand move this back to about there So those walls intersect a little bit and that there's no gap between the floor and the wall So let's just select everything and we can see how that's coming together So that will do it for this step in the next step I'm going to be setting you your first challenge of this tutorial So I hope you're feeling ready to be challenged.
