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.
Continue our exploration of the View Range dialog, in the previous movie we focused on the Cut Plane and how we could manipulate that. But we often want to customize our floor plans and control the way that objects either above or below display. So in this movie I'd like to look at how we can ensure that objects above the view range or below the view range display in the way that we'd like. Now, I'm going to start in this file called Above Below, and I'm going to start in the kitchen area, the break room area over here, and just do a really common example of something that occurs up above.
The rules of the View Range say that if you are either intersecting the cut plane or below the cut plane, that you'll display as long as you're above the bottom of the View Range. Let me explain. Scroll down. Click on the View Range button. Essentially, what I've just said is, any object that appears between here and here will display. You could see that that's actually a pretty thin slice through our floor plan. In this case it's only a little 4-foot slice through the floor plan that will capture all the objects we're seeing.
Now, the object doesn't have to completely be contained within that 4 feet. It just simply has to intersect that band. So if an object starts a little bit below 0 but intersects the range, or starts somewhere here and goes taller than 4 feet, that's OK; in fact, we call that cut. So if you think about all of your walls, all of our walls are much taller than 4 feet, but we're seeing them bold because they happen to be cut through at 4 feet.
If a wall was completely above 4 feet--so if I took this wall and I took its base offset and maybe I put that at 6 feet or something-- that wall will disappear, because it's completely outside of that 4-foot slice that was allowed. I'm going to undo that. Now, there are a few exceptions to this. There are three categories in particular in Revit that will actually display in this range up here, between 4 foot and 7'6".
Those three categories are generic models, casework, and windows. I'll show you a quick example with casework, because that's a pretty common occurrence. Let's say I wanted to hang some cabinetry on this wall over here. I'm going to go to the Architecture tab, go to the Component tool. Right here I've got an upper cabinet double wall loaded. You can choose whatever size you want. It doesn't really matter. I'll pick a 36-inch-wide size. This is a wall-based component, so I have to highlight a wall. But notice that when I highlight this wall and place it, I see the element. But if I were to open up this section, that element is clearly taller than the 4 feet.
So it's clearly above the cut plane-- there is our cut plane--but it's within that 7'6" range right there. Now if I took one of these cabinets and I moved it up-- and I'm going to move it up just about there-- so you could see the ceiling is in the way, but it's still in the room, but it's just above that 7'6", then it will fail to display, unless of course I went into my View Range and increased the height of the top and then it would redisplay.
So two things have to happen for objects to display above the cut plane. They have to be one of those three categories-- generic model, window, or casework--and they have to be within that zone up above. Now, what about the other direction, down here? Currently, it says 0 and 0. So really this zone in here is kind of a moot point, because there is no zone there; both of the numbers are the same. But if you change those numbers such that you end up with a zone there, there is another very specific set of rules that apply, and the best way I can describe this--I'm going to cancel out here.
I'm going to open a different view. I'm going to go here to my foundation view. Now I happened to be zoomed into the same part of the floor plan, but you could see I've got foundation wall here and I've got a footing down below. Now, if we took a look at a section here-- let's reopen this section-- you can kind of see that. Here's the foundation wall, and here's the footing down below. Now it's pretty common to want to see this outline of this footing to be a dashed line, to indicate that that's down below.
So you can see it's displaying, but it's not displaying dashed. So let's look at the View Range settings in this floor plan, right here. I've changed them slightly. The cut plane is little lower because we're in the foundation, and the bottom of the view range is at -5, but I've changed the view depth to -10. So I've created this 5-foot zone which includes all of the footings. Now if you create that zone, if you change those numbers like that, then the trick you need to know is, those objects are now displaying using a special line style in Revit.
It's a built-in line style called Beyond. Where you configure that Beyond is on the Manage tab, and then go to Additional Settings, and we want to look at Line Styles. I'm going to expand Lines. There is my Beyond line style. It's currently displaying as a pen Weight 1, Black, and a solid-line pattern. So all I have to do is change this to some sort of a dashed pattern. I'm going to choose this Dash 1/16 of an inch, click OK, and now you'll see all of the footings show as a dashed line.
It doesn't matter that they're foundations. It doesn't matter the category. I didn't make a change to that category; I made a change to that Beyond line type. So anything that occurs in that -5- to -10-foot range would display this same way. The two other settings in the View Range dialog-- the zone above and the zone below--they can be a little bit esoteric. They can be a little bit difficult to understand. But they offer very powerful means to control very specifically what you want to see in your floor plan for items that either occur way below or items that occur above over your head.
