So, in Autodesk Infraworks, you can reduce errors by utilizing the Point Cloud in Infraworks and bringing that information into Civil 3D.
00:10
Inside Infraworks, there's a Point Cloud modeling tool.
00:14
That Point Cloud modeling tool can be used after you've performed a Point Cloud terrain analysis.
00:20
And after you've processed that Point Cloud, you can begin to extract features such as vertical features, linear features--
00:27
vertical features being trees, streetlights, signage.
00:30
And then, at that point, you can export that information out.
00:33
You can have a richer model in Infraworks.
00:35
You can export that out to Civil 3D.
00:38
So, let's go over to Infraworks.
00:39
And let's see how we can use the Point Cloud modeling tool.
00:44
So, we're here in Infraworks.
00:45
And once we've completed the Point Cloud terrain processing, we can now extract objects.
00:51
We've got linear feature and vertical feature extraction.
00:54
We'll do the vertical feature extraction first.
00:57
We'll go ahead and select that, "Vertical feature extraction".
01:02
Give it just a minute.
01:04
It's going to go out and identify things that it can apply city furniture to, such as stop signs, street lights, trees.
01:13
And once it's completed, it'll bring up this Point Cloud modeling dialog box.
01:18
You can see here that under the "Assign a Feature," we've got 1,550 that it's identified.
01:24
We can look at the categories.
01:26
Trees, signs, street lights, unidentified, unknowns.
01:30
And we can start to filter that out a little bit.
01:32
So, if we go into signs for just a moment.
01:35
And now thinks it found 18 signs.
01:41
We can filter that a little bit more.
01:43
So, I'm going to come back here to all of them.
01:46
And maybe I want to filter it based on height.
01:47
So, I know that, most likely, if I go between 3 feet and let's just say, 15 feet, it's going to start to pare that down.
01:60
It's only going to find those things within that range.
02:04
Adjust this a little bit more.
02:08
You see that number slowing down a little bit.
02:10
Under the category-- let's change that back to signs.
02:14
Let's just kind of cycle through here.
02:16
It's going to do its best analysis to see what is a stop sign, what is a streetlight.
02:22
So, maybe this is a stop sign.
02:24
Maybe there's a stop sign coming in here.
02:27
We can choose here. We've got sign.
02:30
We can choose the rule style over here or the manual style over here.
02:35
So, anything there that is selected, we can cycle through.
02:40
We can identify things.
02:41
There's most likely not a stop sign in the middle of that railroad track.
02:44
Sometimes it's going to find some things, you need simply select it and delete it from your screen.
02:52
The same thing trees. We want to put some more realistic trees in there.
02:55
This is going to cycle through a lot.
02:57
So, I'm going to change this number here to 100 feet.
03:00
It's probably going to find some bigger trees, and just cycles through all that.
03:07
It's going to place that model in.
03:09
So, quickly after we do that Point Cloud terrain option,
03:13
we can start to identify some of these vertical features and just start supplementing our model--
03:19
a little bit more realistic based on that Point Cloud and based on the processing of it.
03:24
The next step we'll get into, we will look at the linear feature extraction option.
