Using visibility graphics - Revit Tutorial

- [Instructor] Once you've inserted a point cloud into your project you can affect the way that it looks by going into Visibility/Graphics. And you can find your Visibility/Graphics underneath Properties, and in this case, go to Visibility Graphics, and select on the Edit button, or type in VG, or the letter V twice. Here underneath Visibility/Graphics Overrides, we can now see that we have a new tab called Point Clouds. Now Point Clouds tab only shows up if you actually have a point cloud loaded into your project. When you click on the Point Clouds tab, here you'll see all the different point clouds that you've loaded into your project. If you've loaded seven different point clouds, into the project, they would all show up here on the list. Additionally, If we click on the little plus, next to Combined, and here we have Scan Locations, we can see that it currently lists: pc, and pc2. Those are the two separate point cloud files that were combined into this one point cloud file that we brought into Revit. What that means is that we can control the way that each of those point cloud files show up here inside of our Revit model. As an example: If I clear the check box next to pc2, click on Apply. Right now it looks like that nothing much has happened, but if I click on the bar, drag this window down, we can see that one half of our point cloud is now been shutoff. I'll move my Visibility/Graphics back up. I'll now put a check mark next to that pc2. Clear the check mark next to pc. Click on Apply. Now if I move the Visibility/Graphics Overrides down, we can see that the other half of the point cloud in now there, and the pc part of the point cloud has been shutoff. To turn both of them back on, just make sure that there's check marks next to each one. Now the difference between turning them on in Visibility/Graphics, or turning them off in Visibility/Graphics and turning them on and off in the Worksets, is that: if you turn them on and off at the Workset level then Revit won't process that information if they're off in the Worksets. On the other hand, if they're turned on, or off here underneath Point Clouds, then Revit's still going to be processing them, even though they're turned either on, or off, in the the Visibility/Graphics. Meaning that it's easier for Revit to process point cloud information by turning them on and off at Worksets than it is in your Visibility/Graphics. On the other hand, it's also a little bit easier to maybe turn on and off the point clouds that you just want, by turning them on and off here underneath the Point Clouds tab as opposed to having multiple Worksets for each one of the point clouds that you load in. So, it becomes just a process as to how you want to turn on and off your point clouds and how you want to speed up the process of doing your modeling inside of the Revit environment. Usually what I do, is I'll usually leave the point clouds on in the Visibility/Graphics, and then turn off the appropriate Workset. But under certain circumstances, such as what we're looking at right now. Turning one or the other on or off, might make more sense. Additionally, where we have Color Modes, we can actually affect the color of the way that these point clouds display. For instance, if we chose: single color. See how it says Red? I'll click on OK to that, move this over to the side, click on Apply. See how the entire point cloud is now turned Red? If I change it to Elevation, with the highest Elevation as red, and the minimum Elevation as blue, I can then click on OK. Then we'll start to see that based off of the elevation, when I select on the Apply button, the highest points are red, the lower points are blue. Then there's options for Intensity and Normals. I usually don't go into the those, but just so that you can see it, if I select on Intensity, we can see that the maximum intensity being white, meaning those are the ones that are closest to the point cloud scans or the points that happened to be like the densest. As opposed to minimum intensity. Click on Apply. In this case it's almost all gray, and the reason is, is that they will all have a very similar level of intensity because I was able to do a very dense scan. So, we can change all this and the way that they display, in this case I will change back to the RGB and click on OK, by going into the Visibility/Graphics. And I will click on Apply, and then finally click on OK to get out of the Visibility/Graphics and see my entire point cloud again.
