Join Paul F. Aubin for an in-depth discussion in this video Creating a detail callout, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Instructor] In this and the next few videos we're going to talk about the detailing process in Revit. Details are an integral part of any architectural documentation package. However, one of the challenges with working in the building information paradigm is that there's often this temptation to over-model everything. In other words, it's theoretically possible to add items like flashing, fasteners, bolts and screws directly to your model. However, typically such items only need to be shown in large scale views and in smaller views they actually get in the way. So we want to resist the temptation to model such element.
Furthermore, there's actually little payoff to model them and you often pay a high price in diminished computer performance when you choose to do so. So for such items we want to continue to rely on traditional detail drawings. This has always been the case in architectural communication and Revit offers a full complement of tools to facilitate the detailing process. And it does so in a way that maximizes the potential of both the live 3D model and those detail embellishments that we're adding to the view on top. So to get started we need to create a detail callout view.
Now I'm beginning this process in a section cut of my stair and what I want to do is create an enlarged detail of the landing condition at my stair. So I'm going to go to the View tab, and click on my Callout button, and we've used this before, but this time all we need is a simple rectangular Callout. And what I want to do is kind of drag the Callout around the area of the stair that I want to enlarge in a detail. And that will create the Callout on the view complete with the Callout bubble over here on the right hand side.
Now I'm just going to double-click that bubble and that will open up the view. Now if we look over here in the Project Browser you can see that that created Section at Stair Callout 1. Now you could right-click and choose Rename or if you just select it in the Project Browser you can press F2 to achieve the same thing and give it a more descriptive name, like Stair Landing Detail. Now the next thing you'll notice is that it came in at a scale of 1 to 50. Now that's just what it typically does, it takes the scale of the view that it came from and it doubles it.
So we went from a 1 to 100 scale to a 1 to 50 scale. I don't think that's going to be large enough for our detail, so I want to increase that scale and I'm going to go all the way up to 1 to 10. Now you will see that adjust the graphic slightly, particularly you'll notice that in the grid line right here, which became significantly smaller. Now I'm going to type z + f to zoom to fit and that'll just bring me in a little bit closer. Now the next thing I want to talk about is the Crop Region of this detail Callout. Now if I move my mouse near that rectangle you're going to see it highlight with a bold line and then there'll be a second line around it that's dashed in.
So there's actually two different Crop Regions enabled in this Callout view and I'd like to talk about both of them. Now if I select it we've seen the Crop Region before, that was the subject of a previous video, so if I scroll down here on the Properties palette, under Extents we have Crop View and Crop Region visible, and those are the two settings that we've talked about previously. Now as you may recall, the Crop Region is this inner rectangle here and it actually adjusts what we're seeing. So I could actually fine-tune this Crop Region right now and either reduce it or increase it to show more or less of the detail area.
Now what's important to understand when you do that is if we went back to the original Section at Stair view that actually changes the shape of the Callout as well. Those two things are one and the same. So I'm going to return to my Stair Landing Detail. Now you may recall that you could turn off the visibility of that Crop Region by unchecking this box and in fact, we could even turn off the cropping behavior altogether. That would just simply show me the entire model again. The Crop Region is still here.
So I'll just check it again to reenable that. So what about this dashed line? Well that's the third checkbox, that's called an Annotation Crop. And the easiest way to understand what that is is to demonstrate it. So I'm going to create a piece of text. Now if I select this piece of text and I'm going to slowly start to drag it, notice that at some point it'll disappear. Where it's disappearing is when it hits that dashed box. So that dashed rectangle is the Crop Region for any annotation that you place on this view.
Any annotation that falls outside of that Crop Region will not display. Now of course, the easiest way to deal with that is to just enlarge that Crop Region and then the text note will display. Now I'm going to do Z + F to zoom to fit and the other way to deal with it is to just decide whether you need it at all. So honestly for details I don't really think the Annotation Crop is really that useful, so I usually like to just turn it off. If you're doing a floor plan and you're cutting the floor plan into two sections and you have a match line in between then the Annotation Crop can be really useful in that situation, but for details I just want to show all the annotation, I don't want to have to deal with the Crop Region.
So I'm going to turn off the Annotation Crop there. Now the last step in getting this Callout configured and getting us ready to create the detailing is to consider the depth of the Callout. Do you see these items right here? This is actually a mullion, this is another mullion of the window off in the distance. The original stair section that we created this Callout from is determining how deep we're seeing into the model. So if I deselect everything and I scroll down a little bit further from the Crop Regions you'll notice that there's Far Clip Offset, Far Clip Settings.
The Far Clip Settings have two choices, Same as parent or Independent. Well, right now it's Same as parent, which means that it's going back the full depth past the curtain wall. I don't really want to see those distracting elements here in the detail, so I'm going to set it to Independent. When I do that I'm now able to change the Far Clip Offset of the Callout without affecting the parent view. So I'm going to try a number like maybe 1,500 and then I'll apply that. Now you'll see the mullions disappear, so we're now cropping much closer to the viewing plane, and in fact, it looks like we're cutting through the stairs now, so we're actually losing the railing off beyond in the distance.
But actually for this detail I think that's okay, so I'm going to accept that. Now if later you change your mind you can always go back in and adjust that Far Clip Offset. So usually what you want to do is create your Callout, configure its settings, which might include adjustments to the Crop Region, it might include adjustments to the Far Clip Offset, and I don't have an example here, but it might also include visibility graphics modifications. So we've talked about visibility graphics in previous videos, in some cases you're going to want to hide certain elements, show other elements, so you want to get the model portion of your detail displaying as optimally as possible to support the purpose of the detail that you're about to draw, and then in the next step you'll begin adding the two dimensional view specific embellishments on top of that view, and that'll be the subject of the next few videos.
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.
