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.
