1 00:00:07,000 --> 00:00:08,000 What we can do now. 2 00:00:08,000 --> 00:00:13,000 We can copy this ground floor layout. 3 00:00:21,000 --> 00:00:22,000 And we can put it there. 4 00:00:22,000 --> 00:00:26,000 Now, what we've done up to now, if we've got anything on this side, we've just mirrored it to that 5 00:00:26,000 --> 00:00:26,000 side. 6 00:00:26,000 --> 00:00:33,000 You can't mirror this floor layout because it will be a different floor layout if you were to mirror 7 00:00:33,000 --> 00:00:34,000 that. 8 00:00:36,000 --> 00:00:45,000 Then when you look at the floor plan, if I just show you if I was to mirror this and you can mirror 9 00:00:45,000 --> 00:00:49,000 it even though it's an xref, the problem is. 10 00:00:51,000 --> 00:00:53,000 I'm just going to move it. 11 00:00:53,000 --> 00:01:01,000 If I was to do that, our floor layout drawing shows. 12 00:01:04,000 --> 00:01:08,000 This plan with reception down here and the door there and our mirrored version. 13 00:01:08,000 --> 00:01:10,000 It would be everything would be mirrored. 14 00:01:10,000 --> 00:01:11,000 So reception. 15 00:01:11,000 --> 00:01:13,000 So you can't just do that. 16 00:01:13,000 --> 00:01:19,000 It would end up being we would need another one of these drawings for the mirrored version, and they 17 00:01:19,000 --> 00:01:20,000 just wouldn't do that in the real world. 18 00:01:20,000 --> 00:01:22,000 There's no reason for doing it. 19 00:01:22,000 --> 00:01:28,000 So what they would do here is you would just rotate it. 20 00:01:30,000 --> 00:01:32,000 So I'm going to rotate that by 180. 21 00:01:39,000 --> 00:01:42,000 I'm going to move it there and then I'm going to copy it. 22 00:01:52,000 --> 00:01:52,000 And there we go. 23 00:01:52,000 --> 00:01:55,000 So we have our eight building layouts. 24 00:01:55,000 --> 00:01:56,000 If we come down to our xrefs. 25 00:01:56,000 --> 00:02:05,000 Now You can see, even though we copied it, we still only have one x ref because we're only loading 26 00:02:05,000 --> 00:02:06,000 that file in once. 27 00:02:06,000 --> 00:02:08,000 We're only loading the information in once. 28 00:02:10,000 --> 00:02:12,000 And what I'm going to do, I'm going to demonstrate again. 29 00:02:12,000 --> 00:02:14,000 Just I'm not going to delete anything. 30 00:02:14,000 --> 00:02:21,000 I'm just going to add let's say add a I don't know a little extension on the front there. 31 00:02:21,000 --> 00:02:22,000 Save that. 32 00:02:24,000 --> 00:02:26,000 And we'll go back here. 33 00:02:26,000 --> 00:02:28,000 Let me close this and I'll click on reload. 34 00:02:28,000 --> 00:02:33,000 And it's it's added it to all of them because the original designs changed. 35 00:02:33,000 --> 00:02:34,000 So that's the power of Xrefs. 36 00:02:36,000 --> 00:02:41,000 A lot of companies now use Xrefs for everything. 37 00:02:41,000 --> 00:02:49,000 So what you might find is you would open the site layout and there would be no information in the site 38 00:02:49,000 --> 00:02:50,000 layout drawing. 39 00:02:50,000 --> 00:02:56,000 You would pull in the existing layout drawing, which would just be this row you would pull in the site 40 00:02:56,000 --> 00:03:00,000 boundary drawing as an xref, which would just be this red line. 41 00:03:00,000 --> 00:03:06,000 You would add a car park xref, which would just be it, and it would go on and so on and so on. 42 00:03:06,000 --> 00:03:10,000 So your actual drawing itself doesn't contain anything other than xrefs. 43 00:03:10,000 --> 00:03:12,000 A lot of big projects are done that way. 44 00:03:14,000 --> 00:03:19,000 So now let me just I've just deleted that. 45 00:03:19,000 --> 00:03:20,000 I'm going to go back. 46 00:03:20,000 --> 00:03:28,000 I'm going to save this and reload. 47 00:03:30,000 --> 00:03:31,000 Okay. 48 00:03:31,000 --> 00:03:34,000 If I view the changes it didn't ask you to reload. 49 00:03:34,000 --> 00:03:36,000 You can also go to your xref manager. 50 00:03:37,000 --> 00:03:41,000 You can right click and just go to reload okay. 51 00:03:41,000 --> 00:03:43,000 And we'll look again at this in a minute. 52 00:03:44,000 --> 00:03:47,000 Now this is a site layout with the ground floor plan. 53 00:03:48,000 --> 00:03:53,000 Maybe we want to show the first floor plan. 54 00:03:53,000 --> 00:03:57,000 I don't know why you would want to do that, but you can. 55 00:03:57,000 --> 00:04:01,000 And what we're going to do is we're going to go to xref manager. 56 00:04:02,000 --> 00:04:04,000 I'm going to highlight the ground floor. 57 00:04:04,000 --> 00:04:05,000 I'm going to right click. 58 00:04:05,000 --> 00:04:07,000 I'm going to go unload. 59 00:04:08,000 --> 00:04:09,000 And you can see it's gone. 60 00:04:09,000 --> 00:04:14,000 But it's important to remember unload hasn't removed it from the drawing. 61 00:04:14,000 --> 00:04:19,000 If you wanted to bring it in you don't reattach it because then you need to specify. 62 00:04:19,000 --> 00:04:23,000 You need to add them all and copy them all and tell it where it is and orientation. 63 00:04:23,000 --> 00:04:28,000 All you need to do is go reload, and it comes back in all the copies in the right place. 64 00:04:28,000 --> 00:04:31,000 It's just you basically turning it off. 65 00:04:32,000 --> 00:04:34,000 So we'll do that and then we'll go. 66 00:04:34,000 --> 00:04:35,000 In fact, let's go back to xref. 67 00:04:35,000 --> 00:04:38,000 And you can also add an extra f here attach drawing. 68 00:04:39,000 --> 00:04:42,000 So I'm going to add my first floor plan. 69 00:04:43,000 --> 00:04:45,000 Same as before the scale. 70 00:04:45,000 --> 00:04:48,000 It's detective of millimeters and the factor. 71 00:04:48,000 --> 00:04:50,000 So I'm going to leave the scale at one. 72 00:04:50,000 --> 00:04:57,000 I'm going to specify insertion point I'm going to specify rotation and click okay. 73 00:04:59,000 --> 00:05:00,000 I'm just going to bring it in like that. 74 00:05:00,000 --> 00:05:02,000 I'm going to move this one. 75 00:05:12,000 --> 00:05:18,000 I'm going to rotate it using this as a reference okay. 76 00:05:19,000 --> 00:05:21,000 Next I'm going to copy that. 77 00:05:51,000 --> 00:05:52,000 And again I don't know. 78 00:05:52,000 --> 00:05:57,000 It's not technically I don't know why you would want the site layout with just the first floor on. 79 00:05:58,000 --> 00:06:04,000 Because really, the first floor on the what's happening on the ground outside is two different levels, 80 00:06:04,000 --> 00:06:06,000 but it's just an example of xrefs. 81 00:06:07,000 --> 00:06:10,000 So here we have ground floor and we have first floor. 82 00:06:10,000 --> 00:06:17,000 We've got a little red tag here saying this one is unloaded, I'm going to save this. 83 00:06:17,000 --> 00:06:20,000 And then I'm going to I'm going to unload the first floor. 84 00:06:21,000 --> 00:06:22,000 So again it's gone. 85 00:06:22,000 --> 00:06:27,000 And now I'm going to insert the roof plan. 86 00:06:31,000 --> 00:06:36,000 All the same millimeters detected it I'm just going to put that there. 87 00:06:39,000 --> 00:06:40,000 I'm going to move in. 88 00:06:40,000 --> 00:06:43,000 Remember I'm using the wall not the overhang of the roof. 89 00:06:43,000 --> 00:06:44,000 So we'll go on that corner. 90 00:06:52,000 --> 00:06:54,000 And this is a bit more realistic than the first four. 91 00:06:54,000 --> 00:06:59,000 I could see why you would want to just show the roof if it was a site plan. 92 00:06:59,000 --> 00:07:01,000 You're just looking from above. 93 00:07:19,000 --> 00:07:21,000 And then I will. 94 00:07:21,000 --> 00:07:26,000 These are, um, symmetrical. 95 00:07:26,000 --> 00:07:30,000 So you could mirror that and it would look okay, but. 96 00:07:30,000 --> 00:07:32,000 But it wouldn't actually be right. 97 00:07:32,000 --> 00:07:33,000 So I am going to do it properly. 98 00:07:34,000 --> 00:07:36,000 I'm going to rotate. 99 00:07:39,000 --> 00:07:40,000 Through 180. 100 00:08:00,000 --> 00:08:01,000 And there we go. 101 00:08:02,000 --> 00:08:03,000 So that is our site now. 102 00:08:03,000 --> 00:08:11,000 And if we wanted to have this drone, we wanted to create the first floor layouts on the site layout. 103 00:08:11,000 --> 00:08:21,000 All we need to do is unload the roof plan and well, if it was a first floor, reload those xrefs or 104 00:08:21,000 --> 00:08:25,000 we can unload that and we can have the ground floor. 105 00:08:25,000 --> 00:08:27,000 So whichever join you want, it's there. 106 00:08:27,000 --> 00:08:34,000 And none of this information is added to the file size because they're all just xrefs that can be unloaded 107 00:08:34,000 --> 00:08:39,000 or reloaded as you wish, and they will all update automatically if that's updated. 108 00:08:39,000 --> 00:08:41,000 So that's the beauty of Xrefs. 109 00:08:41,000 --> 00:08:42,000 That's why we use them. 110 00:08:42,000 --> 00:08:46,000 And that's basically an outline of how to use them in your drawing.
