Join Paul F. Aubin for an in-depth discussion in this video Displaying objects above and below in plan views, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] In this movie I want to consider two special cases within the view range dialogue. What happens above the cut plane, and what happens down in the view depth. Now, I'm working in a level one floor plan, and I've zoomed in on the Break Room area. And, in a previous movie we assigned a view template to control the visibility settings of the level one floor plan. So, if you look over at your Properties palette you'll notice that many of the settings here are grayed out, and we can't actually modify them, and if I scroll down to Extents that includes the View Range.
Now, interestingly enough, I can type VR to get to the View Range dialogue, even though it's unaccessable on the Properties palette. I'm not actually going to change anything, so I think this is perfectly fine to do it this way, but let me just show you another alternative when you have a view template assigned. Since the view template is assigned what we can do is down here on the View control bar we can click this small icon right here, and choose enable Temporary View Properties. When I do that, I'll get this purple border around the screen telling me I'm in Temporary View Properties, and then the View Range button will be available, and I can click it to edit the View Range.
Well, I just want to look at the diagram again, just to kind of remind you of the area that we're talking about. So, once again, the Primary View Range is labeled as item number five. What I want to consider first here is the zone between item number two, and item number one. So, in other words, the small thin space between the Cut Plane, and the Top. Now, most objects have to occur somewhere between Bottom and Cut in order to be displayed.
So, that actually includes the vast majority of the objects you're seeing here in your floor plan. It even includes things like walls. If I were to click okay here, and select one of these walls and change the Base Offset of the wall to anything above four feet, like let me make it six feet for example, and apply it. It's gonna generate an error here. I'm just gonna click okay on there, but notice that the wall disappears. Now, that wall still exists, it's just up above the lower portion of the view range now. It's up above the cut.
So, I'm gonna press CTRL + Z to undo that. That's what would occur with most objects. There are three categories in Revit that will display in that zone between Cut and Top, and those three categories are Generic Models, Windows, and Case Work. So, any other element has to at least touch the view range a little bit. If I select this wall again, and I change the Base Offset to three foot eleven it will still continue to display, because it's just touching the top of the cut plane.
I'm gonna undo again. So, let's bring in a piece of case work to demonstrate. I'm gonna go to the Component Tool. I've loaded this double wall cabinet here, and you can choose any size you want, I'm gonna pick the 36 inch size, and it's a wall-based cabinet so you have to select a wall, and I'll just go ahead and place a couple of those on that wall right there. Now, I've created this section to help us out, so I'm gonna double-click the blue section head to open it up, and then if we zoom in we can see those two pieces of case work. Now, here's the Cut, and these objects are clearly above the Cut, but they're well below Top, and so they continue to display.
If I were to take one of these case work items, and move it up to a point where it's no longer below that top line there. Now, it's still going through the ceiling, but it's still a piece of it peaking into the room here. So, let's go back to level one floor plan, and notice that piece of cabinetry no longer displays. However, if you were to go to your View Range dialogue, and raise the Top of the view range to something higher, then suddenly that piece of case work would display again.
So, that's how objects display above the Cut. They have to be either Case Work, Windows, or Generic Models. Otherwise, they won't display unless at least a little bit of them intersects the Cut plane. Now, let me go back to this section cut, and what about what's going down below the cut? Now, I'm gonna direct your attention these lines here that are drawn relative to the top of footing level, because I'm gonna take you down to the foundation plan which is associated with the footing level, and let's talk about getting the footing objects to display.
Now, initially they won't display, because this is where zero is for the footing level, and the footing is completely below zero. So, if I open up the foundation, notice that all I'm seeing here is the foundation wall. Well, if I go back to that Section View, what I need to do is drop the view depth down below zero in order to get these footings to display. So, in the foundation plan I'll go to Edit View Range, and the setting were changing is this setting right here, and I'll put in negative two.
Anything that occurs between zero, and negative two will now get a custom override applied to it. When I click okay, the footings will display. The custom override says the line work that's used to display these elements within that zone is a special line work called Beyond. If you go to the Manage tab, under Additional Settings, we have several line styles. If I expand the line styles, here's the Beyond line style.
So, right now, it's using a Pen Weight one and a black line color. Let me change that to this bright orange color just so that you can see that, in fact, it's the Beyond line style that is currently controlling those footings. Now, instead of bright orange, I'm going to keep it black, but what I'm going to do is choose something that's a little bit more appropriate, like maybe a dashed line. So, how about a dashed sixteenth of an inch, and when I click okay, now the edges of all my footings are displaying in a dashed line.
Now, if you don't want the stipple pattern to display on the footings you can customize the Footing category in Visibility Graphics and turn off the surface pattern, and we talked about how to do that in the previous movie. So, as you can see, the Below View Range, and the Above View Range settings are a little bit esoteric, and they key in on very specific use cases, but they're very powerful tools, and once you understand how they work you can use them to your advantage to really, kind of, fine tune the way that objects display in your floor plan views.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
