OK, so we have a layout finished here again.
Feel free to change it out as much or as little as you want.
You probably want to get some road markings here.
Maybe some signage you could draw in as blocks put them in, like all that kind of thing.
But you know, let's do that.
We've been over that.
What we're going to do now is we're going to explore using some excerpts.
Now, you may or may not need to be doing this at this stage, you might be happy just with this indicative
kind of rectangle showing where the offices are, but what we're going to do, we're going to bring
the layouts.
For whatever reason, you might want to show the ground floor layouts so you can see the external doors,
what kind of thing you might want to show the roof plan just so you can see how it looks.
Regardless, we're going to do it more as an example of how chefs are used.
So first thing I want to do, I want to go back to our world coordinate system, OK, and I'm going
to click just so we're back in this world kind of coordinate view.
And now I'm going to look at first bringing in the ground floor plan that we created.
So I'm going to go up here to insert.
And under reference, I'm going to go to attach.
I'm going to pull this down, you can attach all sorts of different files.
I'm going to touch a drawing.
OK, so if you navigate to your project folder and go to your ground floor layout drawing that we have.
OK.
It's in the resources section.
If you go to that and click open.
But it's going to bring this in as an external reference.
Now.
I'm going to explain something here.
When we created our floor plans, we drew those in millimeters, so one unit equals one millimetre.
You know, a site layout we draw on in meters, one unit equals a meter.
So really, we want our when we bring in our site plans, we want them to be scaled down by a thousand.
Now, if we were doing that normally as a block or something, we'd bring it in and we'd scale it down
by 0.001, which would be scaled down by a thousand when you attach an extra.
If you can actually have the option, it all because our units are set up correctly, is detected that
the unit is millimeters.
And you can say it's got it's telling us it will factor that and it will scale it down by point zero
zero one.
So because we sell the units correctly in both joints, it's already also kind of intelligent enough
to know that.
So we don't need to change, we can bring this thing with a scale of one and we can let it do its thing
with this hair set correctly.
If it hadn't been set up correctly, you would have to say, OK, I'm going to uniform scale as 5.00
one.
But if we do that now, it's going to scale it twice because it's already doing it here.
It will do it again, so we'll leave that set to one insertion point.
Now, because it's a different scale, we can't we didn't draw it to actual coordinates.
If you were inserting something as an external reference, let's say another company doing the landscaping
and sent it to us as a file and it was done in the correct coordinates.
We could just take that and just bring it in.
And because it was both both drones were doing the correct coordinates to a scale, it would come in
in the right place.
And so a lot of times you will do that because everyone's working to the correct coordinates.
And it's a good way of checking, making sure things come in at the right place.
But in this case, we created it was just a floor plan, so it was just to its own coordinates, girl,
so we can have to insert on screen where it is going and then you have rotation.
Rather than try and work out what rotations can be, we're just going to select on screen, OK, and
we're going to have this as an attachment.
I'm going to click OK, and you'll see now our building comes in so we can see where our 00. was in
the building.
It was just where the crosses here.
Now what I'm going to do, I'm just going to put it there.
I'm going to vote for and I'm just going to put it there for now.
And then I'm going to.
Move it news in this corner of the actual building.
Onto the aisle, then rotate it again, using that as a base point.
But now, instead of president return, I'm going to I'm going to click on reference and the reference
will be, I want.
But corner to corner.
So actually based on that angle.
And now we have this external reference in our drawing.
So if I now go down here.
And you'll see this little is like a it looks like a paperclip and a piece of paper I icon, if I click
on this, we get the extra manager.
Extra effort is just a shortened way of saying external references are both the same thing.
So we get our extra effort manager.
The first thing you have is your actual drawing.
You are in office part ground floor site.
It just comes up at the top.
Lots of drawer open telling you all the drawing files in this file and.
The first one is always itself.
Now, the second one here, this is an external reference and it's our ground floor site, so we can
see now what is actually happening is if we were to load this drawing up, if we were to close it down
and then load it up again, it would load up this this giant office park greenfield site layout and
then it would look for another file, which is a ground floor, and it would load factor in the background.
So that is the main difference with an extra and a block with an extra.
If we haven't inserted this fall out into this drawing in terms of all the geometry, we've just told
it.
Load this file.
And show it, display it on top, so none of that geometry, none of the file size of this is added
to the current file.
And you could have if this file of his office park greenfield site layout was only, let's say it was
one megabyte file size and this office park layout was 10 megabytes.
If you inserted this office part into your drawing, the whole drawing would become 11 megabytes because
it would be 10 from the floor plan and one megabyte of site layout.
So 11 megabytes in total worth of information with an extra F if you inserted it as an extra.
If this file would still only be one megabyte because it's not, the information is only being loaded
and displayed on top.
It's not being inserted and it remains separate files and is a key difference with external references.
Now what I can do just as a demonstration if I write this and go to open.
OK, I'm just going to move it so I can actually open the file.
Let me close out so I can open the file, and this is the original file here.
And if I was to now, for whatever reason, someone came along says, I want a big circle in the middle
and I want to delete all the internal while I want this internal wall and all the action.
OK.
Now, don't do this if you follow in love, because you might ruin your film, I'm just going to.
Safer.
OK.
And if I go back here now, a little message pops up and it says an extra effort was modified.
Reload it.
And if I could really load.
What's going to happen?
Also, Cut is going to reload with the changes, and it takes you into this extra compare.
This is now if this doesn't happen on your auto card, this coming in one of the recent ones, it might
have been 2020 or 2021.
What it used to do and what it might have done on yours is it just reloads and it shows a new layout
and not set this extra off.
Compare, it says, because obviously, if you haven't been told what changed, you wouldn't know.
And so we used to off to hunt for and find out what actually what it's doing.
It's highlighted in red the wall that was deleted and it's put this yellow box around the circle that
was added.
So it's highlighting what has changed, and you can just accept that it's just kind of a display.
But now you can see it just reloaded a file and that's updated to show the latest layout.
Well, I remember I am going to undo, undo, undo.
And I go back and I'm going to click Save, OK?
And again it all and again, my reload.
And it's the opposite, so the circle has been deleted, it's in red and the wall has been added, it's
in green.
And there you go, so.
But that demonstrates the power of extra office, if you imagine the landscaping was done by an external
landscaping company.
That would come in as an extra if we're loading.
And then he did some changes he found, as I'm just about to email, you revision to.
We've made some changes.
OK, all we need to do is save up over the top of our old file.
I'm next time you open a jar or if you've got to open, it will say reload and you reload and it will
put in all that changes because it's an external reference.
So X refs have two benefits two main benefits.
One is that any change is done automatically.
The second is it reduces a fire overall file size a huge site layouts can be split into many different
items.
OK?
