Join Paul F. Aubin for an in-depth discussion in this video Creating cutaway 3D views, part of Revit: Rendering.
- In an earlier movie we talked about creating axonometric views, and it was as simple as clicking the default 3D view icon, renaming it, and then adjusting the view of it slightly to meet your needs. I also showed you how you could turn on the section box, and then use the grips to manually crop out portions of the model in 3D. There's actually a more precise way to do that work. Turning on the section box, it always ends up being very large and the full extent of the building, and then you just sort of have to do a lot of trial and error adjusting the grips.
But if you'd rather define ahead of time what area you want to crop the model, and then you can use the technique that I'm going to show you to actually turn that into a 3D view. So, it's a few steps, but I think it's a nicer process, a nicer overall experience. So, the first thing is to decide what portion of the model you want to view. So I should point out that this is really only pertinent for axonometric views, because when you click the default 3D view, it by default shows the entire model.
So if you want to show a portion inside the model, that's when you have to crop away portions of that model. But a perspective kind of does that naturally on its own, right? So if you just remember that we were able to create a camera view standing anywhere we want, well if you happen to be inside the building when you generate that camera view, it sort of naturally excludes whatever's on the exterior just by the definition of what a camera view is. So, really we're talking about an axonometric technique here. So, what we're going to do is, if I want to see the reception area, but I want to see it in axon, I'm going to start off by creating a Section.
Now I'm going to use the icon here on the toolbar, but you can just as easily use the one in the View tab. And I'm going to create a section through the lower portion of the lobby here. About like so. And then I'm going to take the grips that appear, and pull them in really close to the surrounding walls. Now it's not as important this one back here, because it's outside the building, but i'll close crop that as well. Now of course the section is cutting here, so this is essentially where the person is standing viewing into the model, if you want to think of it that way.
Now let me deselect it, double click the section head, and now we're actually looking at this section. And I can select the crop region here, and I want to fine tune that as well, so I don't really need to see all of this down below grade here, and I'll pull it in just above the roof. So that kind of gives me the width, the depth, and the height of this crop region. Now, unfortunately you can't just hold your shift key down and drag the wheel in a section view, or in a plan view, because these are 2D views, and 2D views can't be converted to 3D views.
But, we can create a 3D view and orient it to a 2D view. And that's what we're going to do. So, I'm going to go back to my default 3D view. I'll just click the icon in the toolbar, that'll reopen our default 3D view here, and then I'm going to go to the view cube, right click, and look for the Orient to View command. Here I've got all my floor plans, elevations and sections listed, and even your other 3D views. Well I'm going to orient to a section, and I'm going to choose that new section I just created.
Now I didn't bother to name that section because I'm planning to delete it, but if you're going to keep that section as part of your project, then it's a really good idea to rename it as well. So I'll go ahead and orient to that view, and it's kind of far away, so let's zoom in and see what it did. And notice that it is now matching the cropping of that section view, but more importantly, this is an actual 3D view now. So if I come over here to the view cube, and I click the corner here, it will orbit it into 3D, and I can choose different corners to orient to different vantage points.
You can even hold your shift key down and interactively drag the wheel to adjust it interactively. Now, here's the section box. So it turned on automatically when you do this orient to view, and now you could fine tune it, so maybe you want to take a little bit of the ceiling away so that you can tip the view down and see into the space a little bit better. So you can start to fine tune it and make adjustments there. So you can see that by starting with a section, you're basically setting what you want the crop region to be, and then applying that to a 3D view, it does most of the work for you, and then you just do some little fine tuning adjustments to finalize it.
Now, when you're done, like we've already talked about, I'll want to take the section box and hide it, because it's usually distracting to keep it visible, and then over here on the Project Browser I'll want to right click and rename this view, and give it a more descriptive name. So that's how you can create a cutaway axonometric view that's looking at some portion of the interior of your building model.
