Hello, and in this particular lesson, we're going to take a look at the view control bar. Before we get started, up the Arch link model from my exercise files. So once you have this model opened up, let's go ahead and follow along. So on my screen here, I have the O2 floor plan opened up and I have the 3D view opened up. And what we're gonna talk about is the view control bar between these two. So right now, going from left to right, the view control bar first shows us the view scale. So this is the scale of this view as is going to appear when we place it on a sheet. The scale is going to control the annotation objects on this view. And what I mean by that, all of these objects that annotate objects and elements. So the room tags, my grid call outs, my section symbols, my elevation symbols even are all gonna be controlled by the scale. Right now it's at 1/8 inch. If I was to click in here and adjust it, let's make it 1/4 inch. You'll see the scale of all of my annotation objects have changed. Many of these same settings for our view control is also available if I don't have any objects selected in the properties pallet. So over here, make sure that your floor plan is displayed across the top, and this view scale right here, if I was to click in here and change it back to 1/8 inch, when I click away from there is going to update the view. Moving on, let's look at the detail level. Right now it's set to coarse. Let's zoom in down here on this area and let's click on here and change the detail level to medium. It's gonna give me more detail in my view. So you see the hatches have now shown up against the walls. If I have to change it back to coarse, the view is gonna update. Sometimes coarse is all you need, but when those moments come where you need fine or greater detail, you can adjust that here. Next, let's take a look at this option here which is a visual style. So to do this, let's switch to our 3D view. If you don't have the 3D view tab across the top, we can scroll down here in our object browser and let's double click on 3D view here to open up the 3D view. In this view, now, when I click on this button for visual styles, I can see the different options. Right now, we're looking at the shaded style. If I switch it to wire frame, my view updates. I can switch it to hidden line and the view will update as well. I can even switch it to realistic, but note this will take a little bit of time to render if you have a slow computer. Right now I'm going to switch this back to shaded. The next control is shadows on or off. Right now my shadows are off. Click once in here, let's say shadows on and you can see shadows show up. Click back in here to turn them off. Save some memory on my computer. Now for this next one, for the crop view, we're gonna switch back to O2 floor. So let's click on the O2 floor tab. Let's zoom extends by clicking once in the window and type ZE, and now let's come over here and let's turn on the crop view. So once this is enabled, now I can come over here and show the crop region. And with the crop region turned on, along with the crop view, I can click on this crop boundary and I can drag it in to how I like it to crop out portions of the view that I don't don't need. Now, if I did not want to crop my view, I can basically just come back down here to this button and click on Do Not Crop View, and my crop regions will be ignored. They're still there, they're just ignored. Turn it back on to recrop the view. Next moving on is temporary hide, isolate. And to do this, what we're gonna show you is I'm going to uncrop this view and I'm gonna turn off my crop region. And let's say, I want to temporarily hide all of my doors. So I can select the door and I can come down here, click on the temporary hide and I can hide the whole category of doors. If I didn't wanna hide the whole category, I could just hide this individual door. That's hide element. But if I wanna hide the whole category, that's gonna hide all of the doors within this view. Click on Hide Category and all of the doors will be hidden. And because I have a temporary hide enabled, I get this boundary. Now in my view, letting me know that there's some elements that have been hidden. The button next to that is to reveal those hidden elements. So let's say you came back in here tomorrow and you forgot what was hidden, you can click on this button right here to reveal those hidden elements and you'll see everything that was hidden. You can turn off the reveal by clicking the toggle button here. And if you wanted to bring back those elements that you hid, you can click back in here and say Reset Temporary Hide. So that was a look at Revit's view control bar. Join me in the next lesson where we will take a look at creating elevation views.
