Join Paul F. Aubin for an in-depth discussion in this video Navigating with the 3D steering wheel and ViewCube, part of Rendering with Revit Architecture 2012.
Navigation in 3D views can be accomplished in a few ways. There is, of course, the wheel mouse, but the Steering Wheel and the View Cube offer the most robust collection of options. Using these two tools, we have many ways that we can navigate in our 3D views. The specific options available on each of these tools depends on the kind of 3D view; so axons and perspectives will actually exhibit different tools. In this movie, we'll explore both the View Cube and the Steering Wheel within each type of view. I am going to scroll down here, and I have two views that we are going to be looking at on the 3D Views category. One is called Aerial View (Perspective) and the other one's called Aerial View (Axon).
So let's start with the axon. I am going to open that up. And this is a view looking kind of at the back of the building, and it has the section box turned on so that it's cropping out part of the ground plane, just so we can focus a little more on the building. Now of course the easiest way to change the vantage point of 3D axonometric view is to simply hold down the Shift and drag with the wheel. And you probably all know that trick by now, so that's pretty easy to do. But notice as I'm doing this that over there in the right corner, the View Cube is actually turning with my mouse.
So it's telling me the general direction there. So that's kind of handy as well. Now what that means is this is actually tied to our view navigation. If you click and hold down anywhere on the View Cube and drag it, it has the same affect. So notice that I can spin the model using the View Cube as an alternative. Now the View Cube also has several hotspots on it. They are labeled, so if I want to look at the front, I can click that and it orients me directly to the front of the building.
If I click the shaded region between two faces, it will orient to those two faces. It's kind of a 45-degree looking at both front and right in this case. And if you do the little corner--any one of the corners around the cube--it will do a 45-degree at all three faces. So now I've got the angle between top, front, and right. And you can click different corners to spin it around in the other directions. So the View Cube allows you to really quickly just sort of use a starting vantage point, and then of course, you could use any other technique to fine-tune and adjust it if you like.
Now the View Cube has lots of other options. There's actually a little tiny arrow here and a little dropdown menu. You can also right-click and get the same menu, go to Home, for example. It takes you back to whatever view is set as the Home view. Now you can go and make an adjustment like so. And I don't think it will remember the zoomed-in, but the orientation it should remember. And if say I want to set the current view as home, now spin out to some other view, now if I say Go Home, it will go back to that view instead.
So that's some of the options that you have in there. You can save a view from here, and that actually creates a named view of it over here. Well, it was already named, so, you could use that if it's a default 3D view. So there's definitely some other options here. You can hide and show the compass, reset the front view, and you can even orient it to other views, which we'll look at in the next movie. What I want to do next is jump over to the perspective view. So I've got an aerial view of the perspective. It's kind of similar. We are looking from a similar vantage point. And we do have the View Cube here, and you can certainly use it in a similar fashion, but I prefer to use the View Cube for axons and I like to use the Steering Wheel here or perspective views.
Now the Steering Wheel is located on this little floating navigation bar. I am going to click on it. And you can use the Steering Wheel in a lot of contexts. You can use it in a 2D view. You can use it in Axon view. But you get the most features and the most functionality when you use it in a perspective view, so that's why I'm demonstrating it here. Now if I roll the wheel on the mouse or drag the wheel on the mouse in a perspective view, I am zooming and panning the picture frame. But if I use the Orbit or Pan feature here on the Steering Wheel--and the way you use any feature on the Steering Wheel is to highlight it and then drag.
So I am going to drag with Orbit highlighted. It actually orbits within the view, within the picture frame. If I drag Pan, it pans within the picture frame, so you are literally panning the camera. So this Orbit and Pan is not exactly the same now as your wheel mouse. So they do two different things. You can also zoom, and that's not like your wheel mouse, because that's actually zooming within the picture frame rather than your wheel mouse which would zoom outside of the picture frame.
Now there are four other tools here in the center. The Center option, you may notice when you're zooming, there's this little green ball right there, or when you're orbiting, there's that little green ball there. You see how that's the center of action? The rotation or the zooming is happening relative to that green ball. Maybe I want to do the centering of the zooming at this tree, or over here at the tower. So I can click and hold down on Center and drag this pivot point, and it will even snap. You can see it's snapping to things. And I can snap it there to the base of the tower and that actually re-centers the entire view on that vantage point, but now if I orbit, you see that it's orbiting around that point.
Or if I pan or if I zoom, it's happening around that point. Up-down, this is kind of like riding in an elevator. So, if I drag it up or if I drag it down, it's sort of like just changing the height of my camera but nothing else. So I am just moving up and down. Here is Look. This is turning my head. So the camera stays still, but I just turn side to side, or up and down. Obviously we are in Aerial here, so I don't want to go too far away.
And then finally, Walk is a little tricky for me. I think you have to be of the video-game generation to really do Walk justice, but when you drag with this thing, it starts to--oops! See, this is what happens. It gets fast for me, and then I go off into space. So, I am not very good at this one, but I'll let you guys experiment with this. But if you're a first-person- shooter video gamer, then you should have no trouble at all with the Walk function, because it would be very intuitive for you. Finally, there's the Rewind option, which I absolutely love.
The Rewind option is if you totally flub the view and you get off in space somewhere and you are lost you can just start backing up through this filmstrip here and it remembers everything you've been doing. And you just drag either left or right through the film strip and you stop wherever you wanted to go. And actually, I kind of liked where I ended up, so I'm going to leave it there, but you can do the rewind and get back to any other previous location. So the View Cube and the Steering Wheel are two really handy navigation tools.
I showed the View Cube in the axon view; I showed in the Steering Wheel in perspective, but you can actually use either one in both views, so I do encourage you to experiment with them in both contexts.
