Scan Navigation overview

“

- [Instructor] When you look at your scans using recap, you can see a clear planar image of the scans using mirror balls and the 3D view feature. When working in AutoCAD, we can also fuse the data using this method. We use the scan navigation in order to filter points and see only the data captured by each individual scan. Let's take a look at scan navigation, and learn how this can help us model with our point clouds. Now I'm going to change my transparency on section manager here, and just make it a little easier to see. Now let's take a look inside our point cloud. If I want to take a look at something in specific in this area here. If I want to look at this valve. Now, if I wanted to model this and needed to pick some points on that line work, I'm not sure if the point I'm picking is on the hand wheel, is it on the flange behind, is it on the ground, is it on the pipe? It's really hard to tell because you're seeing all the points that were captured in the entire project. And these will all overlap and of course you're seeing the front of the object, you're seeing behind the object. We're going to look at this using the scan navigation mode. And that should clarify things significantly for us. So I'm just going to zoom in, and I want to come up to our scan navigation panel here. There, if we come up to this button here, and it says create the scan labels, you have three options. We're going to use the recap files. So essentially what we're going to do is when we'd scanned this particular facility, every scan that we took was represented by a scan location, and if we look in recap we'll see these scan bubbles that'll allow us to see the scanner points only captured in that position. So if we turn our scan navigation on, we can now do this inside AutoCAD. So here's this valve that we were looking at and we weren't sure if the points we were picking were on the hand wheel or on the points behind. Now I'm going to double click, on the sphere here for that one scan. I'm going to turn my transparency off, and now take a look at the difference in the clarity of the points inside AutoCAD. We're only seeing the points that were captured by that one scanner. We're not getting any other points behind it. So if I want to pick a point on this hand wheel, I can only pick the point on the hand wheel, if I zoom in there's nothing behind it. I can't possibly accidentally pick the pipe, because when the scan was captured, the scanner couldn't see that. So scan navigation allows you to look at an almost planar image of the points when we start to model. This makes our point selection much easier. And while we're in scan navigation, we can just jump by selecting another scan bubble, and move into a different view. And this is a really easy way to navigate through the point cloud, and look at different areas. To come out of scan navigation, if we want to go back into our 3D view we're going to go up to scan navigation here, we're lookin the little light bulb, and we're going to turn that off. That jumps us back into our 3D view again. Now, if we want to work in 3D view, and those bubbles get in the way, don't erase em because you might need them again. What we're going to do is come up to scan navigation, and we're going to select the button here right below the little light bulb, and we're going to say hide the scan labels. And this is just a toggle. If you want to go back into scan navigation, we're going to show the labels, and make sure your scan navigation's turned on. And just jump back into one of the scanned positions. Now you can see the value of having filtered point clouds available inside AutoCAD. It makes it so much easier to see what you're working on without having to spend a lot of time cropping out sections of the point cloud to make it easier to work.
