Hi, so let's start with the practical part of our Autodesk civil 3D course.
So in this first class, we are going to learn how to deal with points.
And what I want to mean by same points, they are localizations in space, these points, they have
geographic coordinates, topographic references and information about elevation and this points, they
are imported here into the civil treaty.
And we have all these points linked.
We are going to have our topographic surface of our terrain so that we can work and do analysis and
the projects that we are we want to do here and see the treaty.
So in this first moment, let's learn how to work with dispersants manually, and the first step for
you is to check.
Just let me turn off here.
I'm going to show you what I'm turning off here.
The first step for you is to check how your interface see that here on the top, we don't have the menu
points.
Why?
Because it is hidden.
So you have to check.
You have to click in this arrow pointing down here and you have to come here and show menubar, OK?
And after clicking.
You're going to see another menu.
Another line of dominoes over here, right?
So you also have the option to hide this bar and clicking, um, here on the arrow, pointing down and
hear him hide menubar.
OK, but as we are going to work with points, we need this Manou.
So let's show it again.
Click on the arrow.
Shoman or so that this bar appears again.
OK, so we are going to learn how to work manually with these points, so let's click once in one click
in points and then let's go to create points.
And the miscellaneous I mean, uh, see that we have a lot of possibilities and create point from OK
intersections, um, part of alignment's surface slopes, which are the slopes of the terrain, uh,
we have interpolate we have a lot of options.
Let's click and create points and miscellaneous and let's click in manual.
Now.
OK, so we have a menu over here on the top and what can we do now?
Notice that we have here written, uh, in our arrow.
Uh, please specify a location for the new point.
I mean, we have to click in this location of our point, so let's click in anywhere.
I'm going to click here.
Um, it's a little bit to the left, OK?
And after clicking noticed that what was written now changed, now the softer, softer is asking us
to write a description.
OK, so we can add the description for this part.
In this case, I'm going to type here.
B, this is going to be my point, OK?
You can't type whatever description you want, but it is very important to pay attention on that.
Uh, that when we hit Enter, it asks us to specify point elevation, to specify elevation for this
point.
In this case, I'm going to type one hundred.
And to this cause I suggest you to use the same information on the numbers that I'm using here, because
we are learning together.
You are learning with me, OK, I'm going to hit enter and I'm going to.
Search for another point.
I'm going to our first point was already started, so I'm going to click for this second point.
OK.
Here is OK.
And, uh, yeah, now I'm going to type description G.
And elevation 50, OK, and the softer continue asking me for another point.
OK, I'm going to click.
The third point, I'm going to click here, around here, OK, and I'm going to type the description
M.
Hit, enter and elevation.
I'm going to type 10 and the software asks me another point and in order to finish, I'm going to just
create another one here.
Well, I'm going to repeat the description P, which was the first description that I used and notice
that every point has its own information of coordinates, elevation description.
And this last one I'm going to OK, description P, I'm going to hit enter and the elevation.
I'm gonna type 55, ok.
So I have all my points here, they are very small, I'm going to close this window and in the moment
that we do that, we don't have any more tools so we can click anywhere that the software is not creating
new points anymore.
OK, you can zoom in, just roll in the scroll of the mouse.
Notice that my points, which are in red, they're quite small over here and they have an X on it.
And I notice that I am I'm zooming in and out, rolling the screw of the mouse and notice what I have
here.
I have a red point here, here and here.
And in case it is very hard for you to see, I'm going to zoom in here and notice that now we can observe
on the menu here on the left, we have here the point groups.
And as you can see, we're going to click here, which are the information of the points that were already
created, that were already inserted in this group.
And it's written here all points.
I mean, these points in certain 3D, they can, uh, belong to different groups.
They can be grouped in order to make better.
Our organization and the organization of our projects is very important.
And that's why you can apply this to a project according to our interests.
OK, let's remember that these points are going to be used so that we can create our terrain to link
them the points and make the surface.
So what are the possibilities that we have when dealing with groups and this is very important, we
can create new groups, we can click with the right button and clicking points in both groups and new
and we have this new window.
And what do I want to do in this new window?
I want to create a group and I want to gather up all those points that I created with the description.
OK, so in security, we can create groups, uh, taking into consideration, uh, equal definitions.
I mean, I want to create a group with points that have the same elevation or have the same description.
So this is possible to be done here.
So we have this new window and here in information, I'm going to change the name here name Pontoise
P p points.
I can add a description here.
I'm going to add the point.
Eleven inches, which is relevant points here on the bottom points type can choose this type of our
point, the graphics style.
Uh, so you can select OK, I'm going to put here in basic you have other ones here.
Um, if you click here it will show you how the graphic of this point.
OK, real hole.
Let's see, it is not an X anymore.
It is a ball.
Uh, we have the bound look it is a square right now.
I'm going to keep like that at square.
I'm going to say OK, OK.
Here in point labels tie.
What do we have.
We have the information from that point.
We want to see, uh, what I want to be beside our point.
So we have here, uh, description only just a description, elevation, um, and description.
We also have higher elevation only, uh, NAAFI and Easting, which are the coordinates in space.
We also have, uh, here the point.
No, I mean, the classification of that point, uh, I'm going to choose here elevation and the description.
We can also come here, not just seemed to have a preview.
We cannot hit OK yet.
We have to click in on the include um tab.
OK, and here, uh, we have the information which one should be should be matched for the points to
be into that group and in this case a created point.
Two points with the description P and I want to create a fourth, uh, in the fourth option here, um,
with our description matching.
So we're going to match this description and I'm going to type here B so OK, all the points with P,
we went to this group.
I'm going to click apply and I'm going to zoom here.
This amount of response.
Notice that I'm, uh, zooming in those points with the P description.
And, uh, it shows the elevation, which I said that it shows the description that I set out the Fermat
this square.
And if I go, OK.
If I go here on the top, on the left, I'm going to see the first point that I created also with the
description P Elevation 100 and notice that the other points, the other two ones, they don't have
the description.
So they kept that initial Fermat.
They they are not the they don't have the label that I choose.
And this time the graphic style and the formation of elevation description.
So it is very cool, this possibility, uh, here in 3D, in order to work and modify it, customize
the points here and we can also check another possibility we have here on the left here in point groups
look points P, p, p points.
Uh, we have here our points and points P, which are the the group that we created and selecting it
noticed that on the bottom we have the information of the points, the numbers, uh, the exactly first
point that are created and the formation of if nalmefene point of well, all the information, the description
and elevation.
So now that we already knew how to create the points manually, what are we going to do?
We are going to learn how to add these points from a file generated from topographic instruments, OK,
in this case, a GPS, for example.
So what is going to happen now?
We are going to import this data.
This points to see the 3D.
And with all these points we are going to set to configure our terrain, our surface.
OK, so here on the top, I'm going to click in OK, we have a project.
We going to start from scratch.
So let's click in New New Thing, OK?
Oh, nice.
And what am I going to do now?
We have some format's and this is very important, we have some format's Naji's insert in the treaty
so that the software can recognize and do the right, the correct, um, reading of our file.
And it is going to depend of the two you're using in this case.
We the GPS generated this file so you can open the file.
Uh, of course.
And you can observe can see that we have a file here called Points P and Z and hating twice two clicks.
It will open a file, a text file.
And this file is generated by the GPS instrument of topographic, uh, reading.
So when we open the this file, we can observe that it has a lot of lines.
OK, a lot of numbers.
And note that the name of it is P and and Z, P, P, A and Z is a format.
And this is very important because it really works with a lot of formats of, in addition, part D points.
So each letter of this name corresponds in this case to a segment of information in this text file,
uh, written in English.
I mean, the P the letter P corresponds to point, I mean the point itself.
So it's the first column here that is application of the numbers of the points, one, two, three,
four or five and so on.
We have also the letter A from Easting.
So this is the first information of coordinate and we also have the and from NAAFI, which is OK, ETN
in the coordinates.
OK, we also have the Z well which is the Z axis.
So that's the elevation of the points.
That's the fourth, uh, column here.
And in order to finish we have the D of description, have the description of this point.
OK, so another point very important.
We also have to configure actually we have to pay attention to the C, which really is how the the offsets,
the distancing of this information are done in this file.
A notice that they are the numbers.
They are separated by spaces.
They are not separate, separated by points, OK.
Or any other icon.
And this point here, for example, uh, is the is related to the decimal, OK, to the decimal, uh,
information of the number related to the precision, but the offset of the information, the distancing
is done through spaces.
So let's remember that that's very important.
Let's let's pay attention to that.
And it's very important also that incivility really understands perfectly what kind of type we are 14
and how the information in this file are organized.
OK, so let's go direct to the important part.
Um, so we have our security open.
We're going to click in points, OK, here on the top.
Let's remember, if not not in this manner, you can show it it so click here import and import points
and we have this new window over here.
We can make it bigger.
And what is this new window.
Well first we need to select our file.
So let's click in ADD File and we go to select here points.
You also have this file with you that's clicking open.
And, um, OK, we look we also have here our file being shown, um, notice that we have a lot of files
over here, format and here.
Yeah, and notice that it is written space delimited and this is the spacing between those informations
that I talked OK, and this is exactly how our file is organized.
So we can click, we can observe, observe here on the bottom kind of preview.
The softer shows us draft of how our file is organized in the right way.
OK, so have the numbers over here.
We have the easting, we have northing coordinates, point innovational, which is our elevation of
the point and the raw description.
Right.
So everything is OK.
And another possibility we also have here, right on the bottom is add points to a point group.
I mean, I'm going to check and I already want to create a group for this points that are entering now
into software so that it will organize better my information.
So I'm going to land here at Points Support Group and I can click here and this new window, we can
type the name of this new group.
And I'm going to type group, which is group one.
You can type whatever you want and OK.
And this so this points are going direct to this group.
OK, so let's follow here and before hating, OK, we have some advanced options here to make the edges
of elevation possible.
I will let it marked and transformation of coordinates.
Uh, I'm going to let it unchecked and let's click in.
OK, and in case you can't, you can't see your points.
Um, already sodded they were created over here.
Uh, you can uh, zoom OK to a little bit to load.
You can zoom, let's hit ask or you can ok or you can click twice with the scroll.
Can click twice with the scroll of the mouse.
OK, and so as in AutoCAD, the software extends the zoom and fits it in your visualization of that
point.
So if the project is displaced or very small, you can click twice the scroll button and it brings the
file to the project.
Uh, so we have here all the points and in the next class we are going to continue.
