OK, so if you open up the file office park JF, which stands for greenfield site location services
is something we would have been given by the client.
OK.
Or maybe it was the landowner with be given this so.
And also cut.
We have a drone, which is Office Park GSR sites.
So if we open that and also cut.
And if you zoom extents because they always is, it's it's a road, basically, we've got the pavement
ever side.
We've got a midline kick, which is just for reference, and that's it.
But one thing to to make a note of if you.
If you zoom right out.
You'll see that I was there, remember this is four 00 origin point way of this icon here.
Oh, join is quite a long way from this 00 am is for a site kind of location plan that's normal zero
zero.
It depends what quarters it's me using.
So if you work in a big city, London and New York, something like they would have their own city coordinate
system where everything's kind of any, any design that's done is done on that coordinate system.
That way, you can import kind of background street maps, things like that, maybe working on a big
site such as an airport that would likely have its own coordinate system.
And that way, everything can be kind of configured in relation to each other, and everything comes
in in the same point or maybe working on just some kind of generic system for.
It could be a large kind of remote location, like a farm or something like that.
Okay.
If you just worked on your own house, chances are it's just the bottom left of your land, which is
used as a reserve.
That's fine.
It's the same process.
It's just it's good to know how to work with these coordinate systems where, you know, on zero zero.
OK, so we're going to look, we're going to see how to work with we've got coordinate system in this
example.
Now.
You would probably have more than just a vote on how you would this would be something like a town kind
of map or something like that, but.
For the purpose of this example, we don't need.
And also, it just takes up room when you join, so if you did have VAT, you would usually cut kind
of all out anyway if you don't need it.
So we're just going to pretend this is a road running through a kind of greenfield, quite remote location
and this is our our spot here.
So.
If we go back to.
PDAF.
OK.
Then we can see we've been allocated this parcel of land here, which is a hundred and ten meters by
70 meters.
I'm a bottom left corner.
Is that this coordinate?
So the first thing we need to do is get this red area on our drawing.
OK, so.
Let's take this greenfields site, and let's save as.
And I've already got things I say fast.
Jeff Site survey guy, because this initial drawing.
We're going to produce a set of coordinates around research, so we'll probably have this one will have
each corner and we'll have midpoint and then the surveys can go out.
The can set that out and then they'll go to the actual site and they'll put stakes in the ground, which
will kind of delineate our site layout and the site we're working on.
Basic within the ground, guys can come in and start bulldozing and stripping the top soil, things
like that and then know the perimeter of our site and the boundary, if you like.
So that's our first project.
Get a drone with coordinates of our site boundary to give to the surveyor, and we'll do that now in
this lesson.
So first thing's first, let's look at the we've been given this by the client or the landowner to show
us where we can say outside the possible site we've actually bought or whatever.
OK, so it's easting is 100 thousand meters north is 50000 meters.
Now this is basically X and Y when you're doing coordinates, so X will be 100000.
I mean, knowing a Y will be 50000.
So let's leave that out now and what I'm going to do, I'm going to create a it's called a node or a
point in order to work out, OK, so we can click.
We can have multiple points and these are good for creating things like survey points.
So when a clip multipoint.
And now it's going to ask us to specify this point, so we just need to type in.
These coordinates 100000 by 50000.
So I'm going to talk to 100 thousand, but I'm going to press tab to go to why fifty thousand and press
enter.
OK, now it doesn't look like anything's happened, but we've actually got that point.
If we were to draw a circle from now, we would see.
We've got that point.
I mean, if you highlight it, this now is just a dot, but it can be hard to see a dot.
So what I'm going to do now to change how this point looks, we can type in p type.
OK.
And that will give us this dialog box with different points styles available to us.
And you can choose whichever one of these you like.
The look of this will be normal for survey type.
These kind of points here, and if we select OK, you can see it changes.
How it's viewed is not it hasn't moved.
You can't make a point bigger because it is just a single point.
It's just changed how it's represented.
OK.
And if we present all right, click to bring that look back up.
We also have the option to change the units of the size, OK, so this this point size is how how big
the point is at the moment.
Remember, we worked in meta services effectively a meta.
If we change up to five meters, got all the points are going to get bigger.
OK, now.
You do also have an opportunity to set the size relative to the screen or in absolute unit, so absolute
units means OK, if we say this is one unit, then the point is going to be a meter.
The size of this icon is going to be a meter, whatever we zoom in and out.
It's an absolute units.
It's absolutely one meter.
So it's not going to change just by zooming.
If we set it relative to screen, when you'll see where we end up, so it says it's one unit, OK,
relative to screen is a percent.
So how much percent of the screen does it take up?
So if we say 10 percent of a screen, OK?
Then you'll need the region, and it will go some sense if you zoom out, you can say it's change in
size relative to the screen, and if it doesn't update, you can just type in region.
Four Regenerate and it looked like and it changes its size.
When you zoom in and out, you can.
You can see it generally if you're just using one scale on a drawing like we will.
It's easier to keep it absolute units, and let's just go with five meters for now and see how that
looks, OK, but that is our setting out point.
So I'm going to create a layer in this drawing.
And you could see with all these lies in because.
We've been reusing things, we're using the types of blocks from a building layout, that kind of thing.
We already have all these layers.
That's fine.
But I'm going to create a new layer.
I'm going to create a new layer, and I'm going to call it serve a point, OK?
I'm going to make this right.
If you want to delete all these layers out of your drawing and things like blocks that you don't use
and you can do that with Purge.
But I'm going to call anonymous survey.
And I'm going to make him read.
I'm going to put this on the.
Survey point later, OK, now, if I was to type in Purge Pew, Gee, I can choose all the items in
the drawer, but but I want to delete.
Now you can delete layers from a drawer and as long as there's nothing on multilayer.
But if you've got, sometimes you open the door and there's hundreds and hundreds of layers.
It's a very long process to try and delete them and work out what has got things on.
It wasn't Purge will just purge.
If it will just get rid of them, it will get rid of anything you've ticked here, OK?
That isn't used if you are if you have a drawing file and sometimes you try and email it and it may
be over 10 megabytes in file size.
It might be.
It's got all this information always blocks in line types and layers in the background.
They're not used to a drawing, so you don't even have been loaded in.
Purge would get rid of those out of the back of your neck, and if I was to take all the items and just
say purge on it, I'll say, Do you want to purge, purge all the items and then close if we go back
to this layer manager?
You can see all the layers when used have gone now.
And we just have our survey point.
OK, I'm just going to interrupt because I want I want this John to be safe, but that's something you
can do if you find yourself with lots of layers and a join, then purge will get rid of those.
And that.
OK.
