Join Paul F. Aubin for an in-depth discussion in this video Using sketchy lines and other graphic display options, part of Revit: Rendering.
- Let's continue our exploration of the Graphic Display Options, there's still plenty more features in there for us to look at. So, I'm in a aerial perspective view once again, and if we go to the Visual Style pop-up, at the top of that window, you will find Graphic Display Options. As an alternative, you can go to the View tab, and on the Graphics panel, there's a small little icon right here, that is also Graphic Display Options. So either one of those will do the trick. And in the previous movie we kind of looked at the Model Display options in detail.
So now I wanna show you some of my favorite options in here. Let's start with Shadows. Now, the first item here, Cast Shadows, actually does have an icon in the background here as well, which we've seen in previous movies. If you toggle that little blue ball there, it's the same as checking this box. And if I click up OK, you'll see that little red X go away and it now displays the shadows. The way that it displays the shadows is based on whatever lighting scheme you currently have turned on.
These are the same lighting schemes that we talked about in the movies on lighting. So, if I click here it would take me back to Sun Settings, and you could choose any one of your presets. So you can see that it's casing the shadows based on the rear of the building in the afternoon, is what I named that. So that's turning on of the shadows. But the mode that I like even better is this one here, Show Ambient Shadows. So let me go ahead and click Apply there. Now, you can see that it just sort of does a really subtle kind of shading to this view.
It's almost like somebody pulled out a piece of charcoal and came over and just kinda smeared around the edges with this charcoal. You see how you're getting a little bit of pooling of light over here, where two faces meet, or it kinda dirtied up this surface of this wall a little bit, and darkened it in some of the corners, I think that effect is just really, really nice, and sometimes that's all I do is turn on the ambient shadows and generate my rendering, export this out, so I could literally OK out of here, go to the big R application menu, go down to Export, and export this as an image.
And its a black and white shadow display with ambient shadow display rendering, you put in the size that you want here, or you just say zoom it to 100%, you pick your file format, png or jpg or whatever you want and you click OK. So that can be a really, really nice way to do it. Let me show you this in another view. If I go to the 3D Lobby view, it's currently set to shading. So what I'm gonna do is, you can turn on shadows with it in shading, doesn't work so well on an interior because you see over here there's just a little bit of light? If the sun isn't actually coming in that window, then shadows isn't gonna work so well.
So it's kinda dark, so let me turn that off. But you can turn on Ambient Shadows whether or not you're casting the shadows. So these two setting are independent. So if I say Show Ambient Shadows, and do that, you can see it kinda adds that little bit pooling of light over there and over there, well watch what happens if I actually change this back to Hidden Line. Wow, that looks fantastic. I just love that view. It doesn't really need to be much more than that sometimes, this is a nice black and white hidden line view, but turning on the ambient shadows just gives it so much more life.
Look at it without ambient shadows, and now look at it with. What a huge difference. And again you can export that to a rendering and use it any way that you'd like. So sometimes that's all I do, is I just go to Hidden Line, turn on Ambient Shadows, and that's it. Now, right below that is something called Sketchy Lines. Now this is if you wanna kinda give it that hand-drawn effect. So if I enable the Sketchy Lines, I get these two settings here, Jitter and Extension, and they have sliders, or you can just type in the numbers here, So let's just set them both to 1 and click Apply.
Now, you can kinda see what that did, right? Now if I really jack these up, it'll be more obvious and you'll really start to see what it's doing so it's really just kinda just jiggling all the lines and making it look really rough. Now obviously you don't need it to go that far in order to get the effect here. But just give it a little bit of Jitter and a little bit of Extension. The extension is where two lines come together, a little difficult to see a good example here, let's jack up Extension really high. And you can kinda see where lines overlap one another, like right there and right there, extension is that crossing of two lines kind of letting them go past one another, and jitter is, of course, the wiggle to that line.
So, just dial up those settings a little bit whether or not you have ambient shadows on or not, it can be an interesting effect. I think it looks better with ambient shadows, so I like to do both. And that's another way to do a non-photorealistic presentation that can ee-vay a certain kind of mood and a certain kind of quality. Now, let me OK out of here, and go back to our aerial perspective again. And I'm gonna go back to a mode that we looked at in the previous movies. So, let me go to Graphic Display Options, and I'm gonna change this to Shaded, I'm gonna temporarily turn off the Ambient Shadows, and let's click Apply.
And so it kinda looks like that, I left the actual shadows on, but you may recall that we talked about doing Realistic. So if I click Realistic and I Apply it, in my opinion this feels a little too dark. So even though I've got afternoon sun, the whole thing just feels a little dark to me. Well if you go down here underneath Lighting, you actually have some control over the way this lighting is cast in this shaded view. Now the problem is that we're not doing any ambient light. And if you think about it, when the sun hits surfaces, it bounces all over the place and so it even lights up the dark areas.
If I kick the Ambient up a little bit and click Apply, it starts to lighten the whole image overall. Now another thing you can do, is you can actually change the intensity of the sunlight. And it's subtle, but you'll see it start to brighten things. And then you can even increase the amount of brightness in the shadows. So when you start to look in the shadow areas, there is a little bit of transparency to them when you start to increase that. So, it's uniform, it goes across the entire image, but it starts to lighten everything up and maybe not make it feel so dark.
Now obviously the amount of these sliders really depends on the kind of shading you're doing, 'cause if I go back to regular shading, this is maybe a little too washed out now. So these numbers work well for Realistic, but maybe not as well for Shading. So it's definitely something you're gonna want to play around with. But you have a great deal of control over these non-photorealistic renderings just by spending some time in here and adjusting the sliders, and fiddling around. And here's the best part, when you get a bunch of settings that you like, you can click here to save this as a View Template.
You can give it a name, be as descriptive as you can, and when you create that, you now have this View Template that you can then apply to other similar views. And it will apply all of these settings for you. Now this works just like any other View Template in Revit does, but knowing that you can use them here for these Graphical Display Options is really helpful 'cause it's gonna save you a ton of time. So make sure you get familiar with the Graphic Display Options because sometimes all you really need is a view that just shows a little bit of emotion.
And it doesn't necessarily need to be a photorealistic rendering, and you can save a lot of time by generating one of these shaded views that has just a few of these settings to give it that extra little bit of punch, and save yourself the time of having to wait for a hour's long photorealistic rendering to generate.
