INSTRUCTOR: Creating surfaces from point cloud data

00:06

in InfraWorks is an important part of existing conditions

00:11

modeling.

00:12

This course contains three objectives.

00:15

We begin with this set-up and data import.

00:18

Then, we look at ground processing settings

00:20

in InfraWorks for surface clean-up.

00:24

And finally, we see the export of the surface from InfraWorks

00:27

for use in Civil 3D.

00:30

The workflow in InfraWorks begins

00:32

with the import and configuration

00:34

of the point cloud data.

00:36

Next, it is important to set the processing rules.

00:39

Then, we generate the point cloud terrain.

00:41

Next, surface layers manage the data

00:43

for visibility and hierarchy.

00:46

And last, the surfaces are exported in IMX format

00:49

for use in Civil 3D.

00:51

Let's look at an example.

00:53

I have a base map surface and an aerial image

00:56

created from the Model Builder tool in InfraWorks.

00:59

We could see the contour lines are very straight and uniform,

01:03

indicating a relatively flat surface.

01:06

And you can see the point cloud.

01:08

After I add the point cloud terrain surface to the model,

01:11

we see the roundabout area is now

01:13

refined with much better detailed information.

01:17

Point clouds can be processed to extract

01:19

both terrain and vertical and linear features.

01:24

In this course, we're only going to be looking

01:27

at creating terrain data.

01:29

You can find more detailed information

01:31

on extracting vertical and linear features on the Autodesk

01:35

Knowledge Network.

01:36

To get the best possible results from our automatic ground

01:40

surface generation, it is important to understand

01:43

the processing rules.

01:44

These settings can be adjusted to refine the resulting terrain

01:48

and save the trouble of doing a lot of manual editing

01:52

and clean-up later on.

01:54

In the three course objectives, you

01:56

will see why InfraWorks is a good way

01:58

to automate the process of filtering point cloud

02:01

data for use in creating surface topography.

02:05

This is especially helpful if your original point

02:08

cloud data is not classified.

02:11

In the first objective, we will begin

02:13

a local or cloud-based InfraWorks model.

02:16

We'll set the correct coordinate system

02:18

and add the point cloud data.

02:21

In the second objective, we look at terrain surface generation

02:24

and management with the data processing

02:27

rules for surface clean-up.

02:30

And finally, in the last objective,

02:33

we export the surface for use in Civil 3D.

02:37

So let's get started on the three objectives in this course

02:40

for creating surfaces from point cloud data in InfraWorks.
