What we can do now.
We can copy this ground floor layout.
And we can put it there.
Now, what we've done up to now, if we've got anything on this side, we've just mirrored it to that
side.
You can't mirror this floor layout because it will be a different floor layout if you were to mirror
that.
Then when you look at the floor plan, if I just show you if I was to mirror this and you can mirror
it even though it's an xref, the problem is.
I'm just going to move it.
If I was to do that, our floor layout drawing shows.
This plan with reception down here and the door there and our mirrored version.
It would be everything would be mirrored.
So reception.
So you can't just do that.
It would end up being we would need another one of these drawings for the mirrored version, and they
just wouldn't do that in the real world.
There's no reason for doing it.
So what they would do here is you would just rotate it.
So I'm going to rotate that by 180.
I'm going to move it there and then I'm going to copy it.
And there we go.
So we have our eight building layouts.
If we come down to our xrefs.
Now You can see, even though we copied it, we still only have one x ref because we're only loading
that file in once.
We're only loading the information in once.
And what I'm going to do, I'm going to demonstrate again.
Just I'm not going to delete anything.
I'm just going to add let's say add a I don't know a little extension on the front there.
Save that.
And we'll go back here.
Let me close this and I'll click on reload.
And it's it's added it to all of them because the original designs changed.
So that's the power of Xrefs.
A lot of companies now use Xrefs for everything.
So what you might find is you would open the site layout and there would be no information in the site
layout drawing.
You would pull in the existing layout drawing, which would just be this row you would pull in the site
boundary drawing as an xref, which would just be this red line.
You would add a car park xref, which would just be it, and it would go on and so on and so on.
So your actual drawing itself doesn't contain anything other than xrefs.
A lot of big projects are done that way.
So now let me just I've just deleted that.
I'm going to go back.
I'm going to save this and reload.
Okay.
If I view the changes it didn't ask you to reload.
You can also go to your xref manager.
You can right click and just go to reload okay.
And we'll look again at this in a minute.
Now this is a site layout with the ground floor plan.
Maybe we want to show the first floor plan.
I don't know why you would want to do that, but you can.
And what we're going to do is we're going to go to xref manager.
I'm going to highlight the ground floor.
I'm going to right click.
I'm going to go unload.
And you can see it's gone.
But it's important to remember unload hasn't removed it from the drawing.
If you wanted to bring it in you don't reattach it because then you need to specify.
You need to add them all and copy them all and tell it where it is and orientation.
All you need to do is go reload, and it comes back in all the copies in the right place.
It's just you basically turning it off.
So we'll do that and then we'll go.
In fact, let's go back to xref.
And you can also add an extra f here attach drawing.
So I'm going to add my first floor plan.
Same as before the scale.
It's detective of millimeters and the factor.
So I'm going to leave the scale at one.
I'm going to specify insertion point I'm going to specify rotation and click okay.
I'm just going to bring it in like that.
I'm going to move this one.
I'm going to rotate it using this as a reference okay.
Next I'm going to copy that.
And again I don't know.
It's not technically I don't know why you would want the site layout with just the first floor on.
Because really, the first floor on the what's happening on the ground outside is two different levels,
but it's just an example of xrefs.
So here we have ground floor and we have first floor.
We've got a little red tag here saying this one is unloaded, I'm going to save this.
And then I'm going to I'm going to unload the first floor.
So again it's gone.
And now I'm going to insert the roof plan.
All the same millimeters detected it I'm just going to put that there.
I'm going to move in.
Remember I'm using the wall not the overhang of the roof.
So we'll go on that corner.
And this is a bit more realistic than the first four.
I could see why you would want to just show the roof if it was a site plan.
You're just looking from above.
And then I will.
These are, um, symmetrical.
So you could mirror that and it would look okay, but.
But it wouldn't actually be right.
So I am going to do it properly.
I'm going to rotate.
Through 180.
And there we go.
So that is our site now.
And if we wanted to have this drone, we wanted to create the first floor layouts on the site layout.
All we need to do is unload the roof plan and well, if it was a first floor, reload those xrefs or
we can unload that and we can have the ground floor.
So whichever join you want, it's there.
And none of this information is added to the file size because they're all just xrefs that can be unloaded
or reloaded as you wish, and they will all update automatically if that's updated.
So that's the beauty of Xrefs.
That's why we use them.
And that's basically an outline of how to use them in your drawing.
