The selection tree is the backbone of Navisworks. Everything you see in themodel is stored there. You can also view the selection tree as compact as well as all of the properties.This is also where you can drag items into your Quantification Workbook. I strongly reccommend keeping the Selection Tree on at all times.
- [Voiceover] What I'd like to do here is look at our Selection Tree. Our Selection Tree is turned on, if we go to our Home Panel select in Search Panel, Selection Tree. If you click on Selection Tree, it turns our Selection Tree on. I'm sure you have it on, or you wouldn't have gotten this far. Now, what I'd like you to do is open up the model so I'm going to click on the Open button right here. I'm going to browse where I'm keeping my files. I'm going to click on Open. Now, as we can see Standard if we drill into it, you can see we have our items in here.
If we go to MECHANICAL, now if I right-click on anything such as Air Terminals, and we come down here and we try to take an item off, we can't do it. So if I hit Escape a couple times. If I go to Home, Tools, Quantification. I'm gonna go to Project Setup. I'm gonna go to CSI 48, I'm gonna go Next, Next, Next, Finish. Now if I go to my Selection Tree, if I right click on Air Terminals, notice we have Quantification.
We can take off the new catalog item, or select the corresponding take off objects. So if I take off the new catalog item, just out of the blue, what happens? Well what happens is, is it adds an entirely new category here. You don't really want to do that. So we have Air Terminals and the problem is we can't really move that up into any other category either. So we're kinda stuck with it. If we go to our item catalog, All we can do really is delete it, rename it, make a new group, or something like that.
So I'm just going to go ahead and right click and delete it. It will delete existing take-offs, yes we want to do that, but if we scroll down to HVAC, now if we go to our Selection Tree, notice that we can find Air Terminals, we can right click, we can go to Quantification, and notice that it knows what we have selected. So we can take off to HVAC, and it's gonna put it in the right spot. Now I'm gonna move my workbook out of the way, and I'm gonna go back to my Selection Tree.
So now you can see how that works, and you can also drill in to see your supply, return and exhaust, so if we go to our Quantification Workbook, and we scroll up to HVAC, drill in the Air Terminals, supply, and if we minimize this, notice how it's gonna categorize it, exactly the way we'd want to see it. Now, I'm gonna go back to my Selection Tree, and for Standard, I'm gonna hit the drop down, and I'm gonna go compact. What this does is just shows you big ticket items.
Architectural, mechanical, sprinkler, electrical, structural. A lot of times I'll come here, if I want to turn off an entire trade altogether. One thing I'd like to show you are the properties. Now there's a lot of properties in here. Tons of them. So looking at my properties, I have all kinds of properties. So I'm gonna scroll down here, until I come up to panel type. If I find panel type, I'm gonna drill into here. Notice that I can come in here and look at just specific items.
So if I come in and drill into family name, I've got System Panel, I'm not sure where to put this one, so if I come into thermal and moisture protection, I guess maybe I'll put it there. Go to my Selection Tree, grab my System Panel, drag, and drop it into here. By doing this I can choose and pick exactly what I want to grab. I have 176 panels, I know that right off the bat. And I know each of my panels. I know the area of them and I know the volume of them.
And of course also if I select it, I can click on my button here, and if I move my manager out of the way, I can zoom out and see that that's breaching through the top there. But I can see each panel, I can go through my model. Again, I hope you're using two monitors to do this. I don't have that luxury.
