OK, so now that we already have our points imported into the software, we are going to create the
surface of our terrain because here we have points.
But they are not linked.
They are just points with elevation.
We have coordinates, but they are not linked.
They are not making a surface.
So in order to create that the terrain first, we need to come here on the left, Manou.
OK, here on the Prospector Tabin surface.
And we have to create our surface inside this menu.
So with the right button.
Here of faces, you're going to market and you're going to click with the right button and you're going
to hear in this new menu and create service.
OK.
You just give one click and we have this new window and what do we have here?
We have the type.
Here and create sort of faced teen sort of face what a lot of students ask me, what is 10 to 10 corresponds
to triangular irregular network.
I mean, a triangular, irregular network.
It will be a denomination to this triangulation in order to join the points, irregular points.
OK, we also have, uh, on the right we have the surface here, the surface layer and the name we can
modify here.
I'm going to type here, Sleepify seems, but is it's the same amount of surface one.
You can type whatever you want.
I recommend you frame of using the same that I'm using here.
And OK, in style, we can choose our kind of our type of visualization of this terrain.
If we click, uh, have these three points here on the right, we can click again and we have some styles
that we can choose border only just using the borders.
We're not going to see the internal surface of the terrain.
We also have, um.
Her elevation in this case, I'm going to show, has concerns and triangles because I want to I want
to visualize this internal triangulations that are going to be done in the surface of the terrain.
And let's remember that this visualization can be changed whatever you want.
OK, so in and triangles, I'm going to click here so I can observe, OK, the internal triangles that
I talked to you, this strangulation, um, if we select, for example, border only the internal part,
it's not seen anymore.
OK.
That's why I'm going to go back here to Caltrans and triangles, ok.
Just checking here.
We already have the name surface one.
OK, name, description, style in random material, I'm not going to change it.
Uh, actually we can, but I'm going to keep it, uh, going to keep the block and I can.
So and that's OK.
I got to keep my block.
And.
OK, let's click in OK, and see that nothing changed yet in our visualization, um, but here on the
left, if we click in plus beside the surface, we already have here surface one.
It was created and now we can open this first surface one, OK, and we can come here in definition.
Uh, and if we click with the right button, I'm going to open this.
OK, um.
What are we going to do now?
We are going to link all those points, um.
So we are going, uh.
We're going to put software to insert, in fact, the surface in this localisation created, how are
we going to do that?
We are creating a surface surface through the points imported, um, using the pins, the file.
So let's click.
OK.
We have here definitions, so we're going to come here in point groups, let's click with the right
button and let's go to AD and why why we're doing that.
You remember when we imported our points, we already created a group to where all of those points went.
We're going to select this group and we're going to select here Ropen one, if we will have other groups
created.
You have the freedom to choose these groups.
That's why I always say in my classes, always when working with knives.
Works of Rabbitt is very important when working with these salters, mainly talking about software that
uses B methodology.
A lot of information.
Organize yourself.
The organization of the information is crucial for the success of your project and to minimize errors.
So let's select a group one so everything has a logic.
Let's ok clicking.
OK, let's wait and see.
Now it has been created the whole surface.
Let's give you a zoom over here and see our opponents and tribulations.
Very interesting.
You can move this way.
Just, uh, hitting the scroll of the mouse.
I'm going to zooming in zoom now, just rolling the scroll.
And now notice this part of the terrain over here, um, in fact, is an interference so we can effect
the terrain comes over here.
Uh.
Yeah, and it follows this part here on the extent over here, and, uh, so we have this little corridor
over here.
And what can you do to emulate the at this conformity over here?
Error created by the software?
We're going to click.
OK, we have to click here in Surface one if you're sitting with the right button and we're going to
go to surface properties.
OK, and in this new window, just let me just.
Over here, we're going to fix that inconsistency that I showed you.
So let's click on the top in.
Yeah, that's a definition, the first moment, let's go in Bude, let's click on this signal in the
screen.
Uh, let's look for the information.
OK, here, maximum triangle length.
I mean, um, use the maximum length of the strangulation.
I'm going to select.
Yes.
Because I want to avoid those infirmities and the hair opened.
Uh, mirror.
OK, this in this case I'm going to type here, uh, 150 meters.
OK, I'm going to apply rebuild the disserve face can click.
So software is going to rebuild our surface and look how much fight over here.
We don't have those lines error lines anymore.
Uh, we have we can follow through the corridors now.
It is correct.
So what are we going to do now?
We are going to create what we call in severe 3-D, the alignment, uh, in this case, you have a terrain
and we're going to build a road in this terrain.
OK, so we have to draw a line, which will be the center line and the line which will guide where the
road is going to be built and see what we call this line, the alignment.
And from it, uh, we can do a lot of works projects and extract extract information.
So in order to create our alignment, let's go to here on the top enlightment and create alignment by
layout.
So let's create this alignment or have this new window.
We can change the name of this alignment.
Um, I'm going to right here into alignment and we're going to choose here central line, which is the
line of the center.
Um, we can't type a description.
Starting station, uh, is the point zero zero.
And in here in the design criteria in general, uh, let's see the design criteria later here in general,
we have the uh, we have the site, we have the alignment style and we have also the alignment label
set.
And what does it mean?
It is in fact the visualization of our alignment.
So let's keep it proposed.
Can click here so you can see it.
And in all labels here, uh, let's change it to major minor and geometric points.
I mean, I want to see the geometrical geometry points and the maximum and minimum values of our points.
OK, and before clicking OK, um, we can OK, we can go to the design criteria.
And what is interesting here, we can the limited here in case the creation of a road, uh, the maximum
speed in this case.
I'm going to put here for example, uh, this time.
Yeah.
I'm going to put here 40 kilometers per hour.
And why is this interesting in this case?
I'm not going to select this option, uh, use criteria based design.
Uh, I mean, I'm going to use, uh, I'm not going to use the criteria because symmetry d it allows
us to check the regulations of the curves, the angles, characteristics of the road if they are according
to the rules, the dimensioning rules, uh, according to the maximum speed.
But in this case it's done.
It's not my interest.
We're not going to use that.
But it's important for you to know that it exists.
Click clicking OK, we came already here to our project and here on this menu on the left, we can click
here in order to draw our alignment and have a lot of options over here.
In this case, we are going to check with curves.
OK, we also have to tell you, with no curves, we're going to click a tangent with curves.
See over here, no curves down there.
Curve and spiral settings are going to click here on the middle with curves and the softer asks me to
specify the point that I want.
I'm gonna use, uh, a quick zoom over here.
Um, OK.
From here I'm going to create will change.
I'm going to start.
I give one click.
I already have my line being drawn.
Uh, I'm going to get another click here.
OK, and the third click moving here down.
Notice that.
The curve is already being drawn.
I'm going to click here.
OK, and so now I'm going to ask I already have three points, OK?
Notice and after hitting ask notice that my alignment was made from the zero.
Have the curve comes this way, have the final mark.
And what is interesting as well in security note is that I also have the distances, OK.
And notice that softer marks the beginning of the curve and also marked where at the end of it.
So and then the alignment come back to be straight.
And in the end, uh, so a possibility we have to extract what we call reports about this of this information.
And here on the left hand toolbox, I'm going to click and we have here in report manager, uh, have
the possibility to extract reports of an element, element of surface, uh, to have the surface have
the profile, um, and we draw the alignment.
So let's click here.
OK.
We also have the option to generate some parts, some information, for example, uh, station and curve,
uh, where we can execute, uh, and then he's going to ask me to select, we can select.
The objects are going to be exported.
I'm going to hit.
I can hit.
OK, and I have to choose the the folder that I want to save.
We can you can choose the type of the file I'm going to choose here html and see OK, I already have
here our file exported with all the information of each part of the alignment, the tangents where the
we also have where the curves.
Uh OK tangent data up station we have where the curves start all the information related to the project.
So in the next class we continue.
