- [Presenter] In this video, we'll continue working on our stair landing detail and we're going to move on to the next step which is to begin adding 2-D elements on top of our 3-D callout view. Now we're creating what we call a hybrid detail here and I call it a hybrid detail because some part of the detail's actually going to be showing you the live 3-D geometry from your model and then we're layering on top of that with 2-D detail components to further embellish what we're seeing in 3-D. And the real goal is to only model to a certain level of detail in the 3-D model that's appropriate for all of your overall scales, and then only when you do these large-scale blowup details would you then add the further 2-D embellishments on top.
Now the 2-D embellishments can be manually drafted or they can be prebuilt components. In this video, we're going to work with prebuilt components. So we're going to go to the annotate tab and then here on the 2-D detail component drop-down, we're going to choose the detail component item. So this will give us access to whatever 2-D detail components are already loaded into this project and you could see those over here on the type selector just like you would with 3-D components. Now, these work exactly like 3-D components.
You've got families and then beneath those you have individual types. And each of these represents some actual element in the model, it's just that this is a 2-D version of that element. So I'm going to start with this channel section here. This is just a 2-D rendition of a steel section, and I'll choose the one size that's in there and then move my mouse into the view window. Now I'm going to zoom in slightly here and you can tap the space bar if necessary to rotate that. But actually, the orientation that is coming in is fine and I'm just simply going to click right about there to place it.
Now, I'm going to cancel out of there and show you what that did. This is a detail item, so it's a very accurate representation of a steel C channel but it's drawn only in 2-D and notice that it's covering up the 3-D model underneath. So if I were to move this, it will cover up the components underneath the model. However, if you go back to the original stair section that this callout came from, notice that we don't see the C channel in this view. That's because that item is of view specific item that only exists here in the stair landing detail.
So that's the basic concept behind working with 2-D detail components. So let's go back to the 2-D detail component tool and right above the C channel is this break line component. Now this one has more of utilitarian purpose. It doesn't represent a real thing, but we're going to use it to help us crop the view so to speak. So I'm going to tap the space bar to rotate this 90 degrees. And then I'm going to kind of click to place it right about here. Now notice that like the C channel, that will cover up a portion of the detail underneath.
Now I'm going to click modify to cancel, select that 2-D component, and then using these control handles, I'm going to stretch that out like so. I'll zoom out a little bit and stretch this all the way up here. So what I want to do is cover up that entire left hand side of the detail. When I deselect it, you'll notice that it's as if the detail stops right at that edge. Now to complete the illusion, I can select the crop region and come over here to the properties palette and turn off crop region visible.
That will make that crop region disappear, and now it appears as though we've only drawn this little portion of the stair landing. So those are the two detail components that we have already loaded into the project. Now we need a couple more components here. So I'm going to go back to annotate, click the component tool, and this time we're going to go to load family. So here in load family, I'll switch to the metric library and then the detail items folder. Now this is organized in CSI master spec divisions.
If you're not familiar with the master spec division numbers it's okay because they have descriptions here as well, verbal descriptions which will help you find your way around. So let's go into the metals folder. Then I'm going to go into metal fabrications and finally metal stairs. Now here there are three families and I'm going to select the first one. Notice the preview of it over on the right. And then if I just use my arrow key, I can go through the other items in this folder and kind of get a preview of each one. So I think it's a good idea to get in the habit of doing that because it gives you a sense of what's contained in each folder and you start to familiarize yourself with what the library contains.
So I'm going to select this first item here, steel pan section and open it up. Now if I zoom in over here, next to the stair tread notice that the insertion point is at the front nosing and at the top of the tread. Now I can line it up directly with the existing top of the tread just fine using that insertion point, but actually, I want it to be shifted over more to the left. So I'm just going to click anywhere to place it. Click the modify tool to cancel, then I'll select the component, go to my move tool, and I want to snap right to the endpoint at the very back of this component, and then drag it over and snap it to the corresponding endpoint on the stair model.
So you can see that this item projects past the ends of the stairs a little bit to create a nosing. Now we're going to fine-tune the size and position and other aspects of this component later. But this is similar to the concept that we've used many other times before, sketch then modify. So in this case, the sketch is let's rough place all of the components we need, kind of like setting up a kit of parts. And then we'll move them around and adjust them where they need to go. So there's one more component that I want to bring in.
So back to the component tool, back to load family, back to my metric folder. I'm going to go to detail items, go into metals and then structural metal framing. Here I want to go to structural steel and the items that are loose here in the structural steel folder are only section views. Now sometimes that will be perfectly suitable, but in this case I actually want to see an angle but not in section, I want to see it in elevation. So in this folder at the top here, AISC, you have actually three different views for each item.
So there's a section, a side, and a top. So what I want to do is scroll down here and find the angles. So I've got L equal angles, and I've got it in section, side, and top. So what I want is that side view and then I'm going to click open. Now this will display a type catalog. Now we've talked about type catalogs in previous videos as well. These will get displayed whenever your family that you're loading in has lots of types. And if you scroll through this list here, you can see just how many choices there are.
So rather than have to load in all of those sizes, you can select a single item, you can select multiple items with your control key or you could select one item, hold the shift key and select a group of items like so. Now what I'm going to do is I only need the very first item here. So I'm just going to select that single item without the control or shift key, and then click okay. Now, when this comes in, you could see that it comes in. It's at a standard length. So I'll just click to place it. And click on my modify tab to finish.
Now I'm going to select this and you've got a little grip here at the end where you can adjust the length. Or with it selected, you can just come over here to the properties palette and input the length you want. I want 150 millimeters and I'll enter that. So now I'm going to want this component to be roughly over here. So I'm just going to drag that into position. So those are all the detail components that I need to get started with my detail. So in the next video, we'll begin taking those components and fine-tuning them to make them match the actual structure of the stairs.
