Find out how to create compelling architectural designs using the modeling tools in Autodesk Revit software. In this course, author Paul F. Aubin demonstrates the entire building information modeling (BIM) workflow, from creating the design model to publishing a completed project. The course also covers navigating the Revit interface; modeling basic building features such as walls, doors, and windows; working with sketch-based components such as roofs and stairs; annotating designs with dimensions and callouts; and plotting and exporting your drawings.
There are many instances when you'll have a need to control the way things display onscreen. In the previous movie we looked at the Object Styles command, which allowed us to change global settings like the line weight, or we could change actually the color or the Line styles in that dialog as well, but surprisingly, we can't use that method to actually hide and show objects. Now there are plenty of times when you might actually just want to hide something. Maybe I need to show a furniture plan and that's going to show one set of objects, and then I need to show a separate power or equipment plan and it's going to show some different objects.
So to turn things on and off, I actually have to use a different method, and so in this movie we're going to look at the Visibility Graphic Overrides feature. And this is a view-specific modification, so any changes I make here won't be global. They will actually apply only to the view that I am in. And I'm in a file here called Visibility/Graphics, and I'm looking at Level 1 floor plan. So when I demonstrate this, we will see that any of these changes will only apply here in level 1. Let's take a quick look. I'm going to come up here on the View tab and click the Visibility/Graphics button, and you'll see it has a shortcut--V+G--and often people will actually refer to this as the V+G dialog, because it's used so frequently.
Let's do a really simple example here. I'm going to kind of move this box out of the way. You can see I have a few doors here in the background. This box looks a lot like the Object Styles. It has the same tabs. It has the same categories listed here. Obviously, there is more columns, and we'll look at some of those, but the checkbox over here was not present in Object Styles, and this allows us to check and uncheck the various objects that we want to hide and show. So for example, if I decided to uncheck the doors and click the Apply button right here, what you'll see is all the doors in the background there disappeared.
Now I can't think of too many good reasons why I'd want to hide the doors in a floor plan, so that was really more of an example. So I'm going to check the box again and click Apply again to turn them back on. Maybe I want to do something a little more practical. If you look over on this side of the plan, you can see here in the background I have some furniture and I have some electrical outlets. So perhaps I have a need to show the furniture sometimes and other times to show the electrical outlets. Well, I could hide my Electrical Fixtures category, print out my drawing, I could come back, turn those back on again, hide my Furniture category, come back print the drawing.
That would be kind of an inefficient way to work. What we typically do instead in Revit is we typically duplicate the view and then set up two different views two different ways, and this is leveraging the feature that I mentioned to you moment ago that anything we do in Visibility/Graphics only affects the current view. So let me demonstrate. So here is Level 1 floor plan. I'm going to right-click it right on the project browser, and I am going to go to Duplicate View. And we actually have three different ways that we can do that. I'm going to demonstrate the first two; these are the ones you're going to use most frequently.
If we choose just duplicate, we get a version of the view that removes all of the view-specific elements: all the text, all the dimensions, all the tags. So you could see here all I see is geometry. If I go back to Level 1, notice I have the door tags and the room tags and the dimensions still. Right-click it again and I do Duplicate with detailing. This time I'll get an exact copy of this view, including all the annotation. Now I'm going to right-click that Copy (2) of Level 1 and I'm going to rename it, and I'm going to remove the Copy (2) portion, leave it Level 1, and I'm going to write Furniture Plan at the end.
So this is my Level 1 Furniture Plan. So what I want to do in this particular plan is I want to configure it to show me only furniture. Now you're going to deal with the annotation elements in a view differently than you are going to with the model elements. We're going to use VG, Visibility Graphics, to control the model elements and annotation elements, you're just going to delete and add them as necessary. So what I'm going to do here is make a window selection around the entire floor plan. That highlights everything. Go up to my Filter selection.
I'm going to click Check None, because you can see I have quite a few categories selected. And I'm going to select only the door tags, the dimensions, and the window tags. So I'm going to select those three categories. Click OK. You'll notice it only highlights those elements, and I'll just simply delete those. Now I'm getting a message here about a constraint that's applied to one of my dimensions. It's offering to either unconstrain them or I can just simply click OK. I don't actually want to remove the constraint, so I'm just simply going to click OK.
Now even though I deleted the dimensions and the tags from this view, if I go back to Level 1 floor plan, you'll see they're still here. It's very important to understand that each view has its own annotation. So that takes care of the annotation aspect, but what about the visibility? As we've said, perhaps the furniture plan doesn't want to see things like these electrical outlets. Maybe I want to just limit it to just the furniture. So to do that I need to use Visibility Graphics. So I'm going to go to VG. I just type VG on my keyboard, and I need to locate those categories that I don't want to see here in this furniture plan.
So I'm going to Uncheck electrical fixtures, and let's click Apply, and you'll see that all of the outlets in the light switches disappear. So that's the effect I was looking for. I'll click OK and that completes my furniture plan. Now I can take this furniture plan and I can use it to generate a second copy. I am going to duplicate again, again with Detailing, but this time I'm duplicating from my furniture plan. So I'll do Duplicate with Detailing. Select it and rename it.
This one is going to be Level 1 Power Plan. Click OK. The difference I want here is now I want to see the electrical fixtures and maybe I don't want to see the furniture. So I'm going to go to VG, turn back on the electrical fixtures, and I can turn off the furniture. Now when I do that, maybe that's the view I'm after. You could see that it's a little bit cleaner there. Of course, going back to Level 1, everything is still here. So this doesn't remove things from the model; it just simply hides them in that view.
Maybe I change my mind in the power plan and I actually want to see the furniture; I just don't want it as intense. So I show you one more feature here. We've been limiting our discussion here to the Visibility column, but there's lots of other columns over here. I'm not going to go through every one, but if we look over here at the far right, we have a column here called Halftone. So perhaps instead I want to turn the furniture back on, but I want a halftone instead. This will be the effect that I'll get. The furniture will redisplay, but it'll display much lighter so that it's maybe not quite so overpowering for the power plan.
So you have a few different ways that you can decide to set things up, but the Visibility Graphics command is this powerful command that's going to allow you to create very focused and specialized views that are specific to the needs at hand. So using it, I can turn things on and off or change the way they graphically display, keeping in mind that those changes only apply to the active view.
