Join Paul F. Aubin for an in-depth discussion in this video Understanding view range, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] In this movie, I want to explore the primary range of the View Range dialog. The View Range dialog has settings in it that determine what we actually see in any floor plan. Before Revit even considers object styles, or before it even considers visibility graphics, it consults the view range. The view range is where the plan is being cut and how much of a slice through the building it should show. So we can find the View Range dialog on the Properties palette with nothing selected in the model.
It's in the Extents grouping. Next to View Range, there's a small Edit button. The keyboard shortcut for the View Range dialog is v + r, if you prefer. Now, here you'll see a series of settings, and down here at the bottom is a small Show button. And if we click that, it actually displays a nice, little diagram to help explain what each of these settings do. Now, in this movie, I'm mainly concerned with the primary view range. So, in the illustration, that's Item Number Five. The primary range spans between Item Number 3, the Primary Range Bottom, and Item Number 1, the Primary Range Top.
Between the two of those is Item Number 2, the Primary Range Cut plane. Now, notice that all of these settings you can manipulate. The only thing you can't change is the associated level of the cut plane. That will always correspond to the current floor level. So, because I'm currently in a Level 2 floor plan, the cut plane is associated to Level 2. Now, I'm not going to change anything in here just yet. I'm going to click OK, and then on the Project Browser here, I'm going to double-click this view that I've created, called Understanding View Range.
Then I'm going to type the keyboard shortcut w + t for window tile to tile this view next to the floor plan, and I will pan the floor plan slightly. So, what you see is, these two windows over here in the conference room are these two windows right here in the elevation. And, with the cut plane at its default of four feet, you can see that it's slicing right through those windows, and that's why we are seeing them. Let's say that we wanted to actually see these clerestory windows up above instead.
Well, you can see here I've drawn this line here, and we would need to be at at least 11 feet in order to cut through those windows. So, if I come back over here to the Level 2 - Furniture floor plan, click on the View Range button again, or type v + r, and change the offset of the cut plane to 11, it should go through and cut those clerestory windows. However, if I click OK, Revit will complain that the top clip plane is now too low. So, in other words, these numbers here that you see, these values, can't get out of order.
So the top always has to be above the cut plane. So, you can make it the same. It could be 11. Or, you could make it a little taller. In this case, I'll just make it 12, just to make it a little taller. And then I'll click OK. So now you're going to see that these windows display, as does another window over here, which we can see in the elevation if I just pan over slightly. There it is right there. However, that solved the problem of displaying the clerestory windows, but now all of the doors and other elements in the floor plan are hidden, because they're too low.
So, let me undo that with Control Z, and let's look at an alternative approach. So, on the View tab, we have something called a Plan Region. You can get there from the Plan Views dropdown. The Plan Region is a way to create a small sketched area that allows you to customize the view range in just that area. So, right here I'm just going to do a simple rectangle, and I'm going to do a rectangle around these two windows.
I'll click Finish, and then I'll be left with this little, dashed box. Now, at the moment, it's still cutting through at four feet. However, if I click this button here on the ribbon, I can now edit the view range within just that small rectangle. So, I'll go back to 11 and 12, and I'll click OK. And now you'll see that it's cutting through those clerestory windows right there. Now let me maximize this floor plan, because I actually already had a plan region in this view.
If I take that plan region and delete it, you can start to see why. Notice that the roof down below was actually being sliced through by the view range of the second floor. And it looked a little bit unnatural. So, what I did, if I do undo, is I added this plan region here, and, by editing the view range up to 12 feet in this case, I was able to get it up above the ridge line of that roof to display in its entirety so it looks as though we were looking down on the roof from the second floor.
Now, here's the challenge we'll run into. To get this other window to display, you won't be able to do that. If you try and overlap two of these plan regions with one another, Revit won't allow that. So you need to make each one separate and distinct. Well, it turns out that, actually, if I just take this one and stretch it over a little bit, that will do the trick of displaying that second window without those two view range objects conflicting with one another.
So, the View Range feature, the primary range in particular, determines where the cut occurs and then how much the top and bottom of that range is, and that, in turn, determines which objects will actually display in your floor plan. And, if you want other objects to display that would not ordinarily be within that normal view range, then you have to look at creating these plan regions to customize the view range in select areas.
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.
