Concrete Bridge Design: Conception to Fabrication

ANDREW MANZE: OK. So I think there's just a few more people left to get logged into InfraWorks. So while that's just been finished off, I think we can make a start anyway.

So my name is Andrew Manze. I'm technical marketing manager at Autodesk. And I've got three good friends at the back there that are going to help us get through this in our reduced time scale, now, because we've lost about 25 minutes due to the technical issues we've been having. But hopefully we'll be able to get through this.

So I know everyone hates a show of hands at these events, but if I can just understand who has got some experience with InfraWorks-- fantastic-- about half of us. Anyone got any Inventor experience here? OK. A few-- you guys at the back. Yeah. I can imagine you probably have. And what about Revit-- loads of people. Yeah. OK.

So the Revit bit is at the end. So if we run out of time, it's probably not the end of the world, but we'll certainly get through the InfraWorks and Inventor stuff, anyway.

How are we doing? I think we got two people left. So everyone can hear me, OK? Right? Yeah.

So has everyone flicked through the handout that I produced? Done your homework? No? All right. This is a very conscientious chap down here. You actually printed it all out and brought it with you. Wow. Beyond the call of duty.

Is that it? Is everyone happy? Has everyone got a working copy of InfraWorks in front of them? Yeah? OK. Great. Right. Well, we'll start then.

OK. So I won't go through the preamble because we haven't got enough time. So we'll just get straight into it, I think.

So this particular course-- I'm going to be teaching this in metric units, OK? So if you're not familiar with metric, it doesn't matter. I'm just going to give you all the numbers anyway. So don't worry too much about it.

But the first thing we need to do is to change InfraWorks to metric units if it isn't already in metric. OK? So if we go up to the menu with the three little dashes-- application options-- down to units-- and then just change that so it's showing metric.

OK. And once you've done that, you can just click OK. OK? So once you've done that, we'll need to open the model that I've produced for us as a basis for this.

So we can go to open, and then it will bring up this browser. And then there's a folder on your desktop, which is called-- what is it called? Data sets. And then you'll find this course-- Concrete Bridge Design.

And then inside of there, you'll find the data set, which, I will tell you what it is in a moment when I load mine up.

OK. So lane end crossing AU, it should be. Anyone not found that? OK. Can someone just give a hand?

So you should see something like this. Here's a desktop. There's data sets. And then inside there, there's the number of this class. And then it's followed by Concrete Bridge Design. It's the only one that says Concrete Bridge Design on it. Should be in there. Yeah.

You OK over there?

Are we working?

AUDIENCE: Yeah, we're good.

[LAUGHTER]

ANDREW MANZE: OK. So this is a model of a crossing over a motorway where I used to live as a child, actually. And it connects-- it's like one of the main arterial routes out of London

OK? But what we want to do is, we want to put a bridge across here. So. All we need to do is to just click on it with the left button just to highlight it. And then we right click. And then you will see, down at the bottom here, we have add structure and then bridge.

OK? And then you should see this strange roller type widget. OK? And we need to position that in the right place. So if you were working with something very early stage, you probably wouldn't worry about numbers. You just-- two clicks and it will produce something for you.

But for today, we want to get something a little bit more accurate. It doesn't really matter, to be honest. But if you want to look right, what we need to type in as the start station is 961.5.

OK? So if you will type that in and then press Return-- OK? That will fix the start of the bridge. And then you can see-- you can roll this out like a carpet, almost. OK?

But what we want to do is fix the length. So if you tap into the length field and then just type 58, that's going to give us a 58-meter bridge.

And once you've done that, press Return, and it will build something.

OK. So That's what we have at the moment. So what we need to do now is make some changes to the bridge. And then we will get into creating some custom content in Inventor. OK?

This looks a bit odd in the [INAUDIBLE]. We don't worry about that. We'll fix that in a minute. There's a reason why it looks like that to start with. OK?

So has everyone got a bridge now? Yeah? OK. No? What happened down here? OK-- So just type in there 961.5. That's it. Press Return. OK. And then if we tap into there-- 58. And then press Return. It should build you a bridge-- slowly.

Oh. There you go. It's doing it. Yeah. There you go. You're good.

OK. So what we need to do now is make some changes to the abutment and the central pair. So if you select the bridge and then click on the abutment itself-- and what you're looking for are these four little rotation handles that come up-- but we're not going to use those.

We're actually going to type in an actual rotation. OK? So if we go over to this side-- in fact, there's two things I want you to do. I want you to just put in a 3-meter offset. OK? So 3 in there. And then for the skew-- minus 14.

OK? And then when you got those typed in, press Return, and it will remodel that with a skew on it. OK?

How is it doing? OK. So once you've got that one done, we need to repeat that for the other side. So just select the abutment and then 3. And then skew-- minus 14--

and then when that's done, we do the same for the pier. We just select it and then look for the skew-- minus 14-- OK. So we'll pause that for a minute.

Everyone happy? Who needs help?

Oh, just by clicking on the-- right click. It seems to be probably set up differently. Yeah. Don't know why it was set on that. Now if you touch it. Yeah. Sure got it now. Yeah.

AUDIENCE: Lost you at the end of the bridge. One-ended bridge.

ANDREW MANZE: My word. Where's it gone? All the way down there. It's gone all the way to the end. It's going all the way down there. What we can do, I think-- Let's put it there, just for a minute, and see when that does. Can't remember whether that's the start or the end. Here we go. That is--

AUDIENCE: That looks better.

ANDREW MANZE: Yeah. And then we want 58 in there. [INAUDIBLE] 58. There you go. That's it. One moment.

AUDIENCE: All [INAUDIBLE] on, so can we just [INAUDIBLE] it?

ANDREW MANZE: Yeah, if you click on-- if you click on that thing. There you go. You can type it in there. 961. And make sure you still have 58. After its remodel, it might change that value. Just make sure it-- just make sure that's right.

AUDIENCE: That gentleman there has got some visibility problem I can't resolve.

AUDIENCE: Here it's showing the girders. How do I remove the visibility of the--

ANDREW MANZE: Yeah. If you right-click--

AUDIENCE: On the road?

ANDREW MANZE: On the bridge itself. So just get the-- OK. And then, yeah. Component Display. So just click that down, and then remove the road, or the-- and the deck, probably, as well.

AUDIENCE: OK. Thank you.

ANDREW MANZE: OK. So a few of you have had a problem with the visibility of the different layers of the bridge. So I'm just going to show you what that is. And when you click on it, if you right-click, and then under Component Display you'll see you can turn on and off the different components of the bridge.

I think that's what-- I think some of you have got that. That's all turned on by default I think, maybe. So just turn Road and Deck off, and you'll get the same view as I've got.

So the next thing I think we want to do is to replace the assembly over the bridge to give us the railings and stuff like that. So the way we do that is by, again, selecting the road this time, right-click, and then there's an item, Road Assembly, and then Replace Assembly.

And if you click on that, you will get this strange orange rectangle. And that's going to be the extent of this new section of road, if you like, with the new properties.

So what we need to do is we need to look at the Property panel, here. And there should be one in there called Bridge Assembly. So you just need to make sure that is selected, and then place this orange rectangle roughly there. It doesn't really matter exactly where, just roughly there.

And then we can stretch this new assembly out across the bridge like that. OK? So that's what you're looking to achieve. And then when you press Return, it will model the new assembly in, and you'll end up with something like that.

AUDIENCE: So-- [INAUDIBLE]

ANDREW MANZE: Right-click. Replace-- Road Assembly, Replace Assembly. And you just want to make sure you've got the-- scroll down to the bottom. There should be one, Bridge Assembly. There you go. So just click that, and then you can, if you zoom out a little bit-- Yeah. So you can just plunk that down. Sort of there would be OK.

And then grab that little grip, and stretch it across the other side. And it's in the-- you'll have to click in place. Just to the amount. That'll do. When you press Return, it'll model it.

AUDIENCE: So this one is off-center. Everything is correct.

ANDREW MANZE: OK. Yeah, that looks, that looks OK.

AUDIENCE: But this one is over the center. Is there any [INAUDIBLE]

ANDREW MANZE: It's changed the-- Yeah, it's probably been mucking about, I think, with it. 58. Probably the easiest way to do that is-- turn that off. Don't know what the value is for that.

AUDIENCE: [INAUDIBLE] more. Little bit more.

ANDREW MANZE: So we'll move 20 millimeters.

AUDIENCE: I think it's 29 you've got to span.

ANDREW MANZE: There you go.

AUDIENCE: So how to add the limit [INAUDIBLE]

ANDREW MANZE: How do you--?

AUDIENCE: Enter it in.

ANDREW MANZE: Oh, right. Yeah. So if you click on the road, yeah, and right-click Road Assembly, Replace Assembly. And then if you scroll down in this, [INAUDIBLE] button, and there's one called Bridge Assembly. So select that.

And then, come over to here. And then this orange thing, you just need to place it there. It's good. And then grab hold of that, drag it over to roughly there. That's good. Anywhere there. And press Return. And it'll turn.

Do you need a bit of help?

AUDIENCE: I wanted to edit the bridge assembly, but I couldn't understand how to go from [INAUDIBLE]

ANDREW MANZE: Yeah, that's-- Yeah. You won't got to do that. You'll have to edit the-- You should be able to. It's not in the Style Palette. So that's the component, there. And you edit the geometry in here. Have you used component roads before?

AUDIENCE: Yes.

ANDREW MANZE: OK. So that's just a component.

AUDIENCE: Road Assembly. Here I just have Replace? So I can adjust to make it--

ANDREW MANZE: You can-- you can replace things using that. Or you go to the-- You click on the road itself, and then--

AUDIENCE: And then I do that. But if I want it shorter, for example, because I have too many [INAUDIBLE], I need to take the [INAUDIBLE] and put it into here? Or can I--

ANDREW MANZE: Yes, you can do it that way.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: Yeah. No, you can't pick it up and move it. Yeah. You've got to replace it pile by pile.

OK. So the next thing I want to look at-- I think most of you have got this done-- is just to change the number of girders. So if you just click on the bridge itself, click on one of the girders somewhere on the bridge, it'll highlight the girder group.

And then if we look to the right-hand side, you're able to push that up to, say, 5. And if you press Return, it will model 5 in for us like so. And then, if we right-click on that again, you can say Apply To All Girder Groups, and it will just copy that arrangement to the next, to all the other bays.

AUDIENCE: What value are you changing with that?

ANDREW MANZE: The number of girders. This one at the top.

Class runs til 4:15. OK. So I don't know if we'll have time to investigate this in great detail, but what I want to do now is to set the girder analysis system running in the background. And then we can come back to it later and examine some of the results.

So if we go up to the purple dot up here, and then click on this one on the end, you'll see Line Girder Analysis.

Sorry. Has everyone changed their girder system to like five beams now? Yeah. OK.

So all we need to do is just select the bridge, go to the Bridges tab, find Line Girder Analysis, and you should end up with this panel. OK? So there's things that you can put in here, job number and that sort of thing. Don't worry about any of that. Just hit Start Analysis. And then as soon as it says Creating Analysis, we can forget about that and move on to something else.

Yeah, you're good. Is everyone happy? Oh, dear. Yeah. That doesn't look right, does it?

AUDIENCE: Sorry.

ANDREW MANZE: Let's see if we can do something about that. What is on this? My word. I don't actually know what has happened here at all. What does that give us?

AUDIENCE: I guess I should stick with [INAUDIBLE] then.

ANDREW MANZE: We can build something really quick here. There you go. And now, if we do that, cross fingers. All right.

OK. So if everyone's got that running, what we can do now is drop out of InfraWorks, and we'll start with Inventor. So what we're going to do is we're going to create something to replace this pier in the middle here. This thing here. We're going to create something completely different to our own design.

So if you want to find Inventor, you'll see on your desktop there is a folder. I think it says-- it's not Programs or Products-- I can't remember. And it's got shortcuts to all the Autodesk products in there. What was it called?

AUDIENCE: Software.

ANDREW MANZE: OK. It's in the Software folder. This is where the fun starts. So has everyone got Inventor running? Yeah? OK.

So what we need to do is hit New. And we need to go in to the Metric folder, I'm afraid. And then we'll hit Standard Millimeters. So I want to double-click on that one there. So you should be presented with something like that now.

So what we need to do is we need to, for this particular thing, what we're going to do is we're just going to create a 2D sketch of a very simple shape. And then we're going to just extrude it a little bit, and then we'll use that as our pier. And we'll dimension it parametrically so it adjusts when it goes back into InfraWorks. So that's what we're going to do.

So if you just click on that little arrow next to Origin-- And we want to choose the xz plane and right-click on it. And hit New Sketch. So we're going to now sketch a simple four-sided shape with an angle to the sides.

So all we need to do is choose the Line tool. And then I'm going to bring my cursor over here. And I want it to snap to the very center of that origin. So that's when it turns green. So I'll click there, and then I will drag it out, making sure that it's snapping to the horizontal axes.

And I want that to be 2,500 long. So I just type 2,500 in there. When it looks like that, you can press Return, and it will draw the line in. And you can zoom out a little bit, and you'll see what it's drawn.

Everyone up to there? Yeah?

So then what I want to do is just get your cursor there. I'm not too fussed about the angle. And I'm not really fussed about the length either. But if you just type in something like 5,000 there, we end up with something like that. Bring that down. So we've got something like that, and then we can just press Escape.

And then, there's many different ways of doing construction lines and stuff like that in Inventor. But I'm literally just going to draw an ordinary line down the center here, and then I'm going to mirror this sloping line to the other side. So there's a Mirror tool. We can pick the mirror line like that. And then we can select this line, then say Apply.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: I don't know. You probably can. Can leave it for this one.

So this is just like drawing stuff in AutoCAD, isn't it? So once we've-- once we have that, then what I want to do is then delete a whole bunch of stuff. So if you just select that mirror line and press Delete, this dimension line and press Delete, this dimension line, press Delete, and then that line on the bottom. We'll get rid of that as well. So we're just left with those two sloping lines.

And then when you've done that, we're just going to draw another couple of lines, but snapped from the top there to the top there, and then from the bottom there to the bottom there. That's what we're after.

Yeah, I see it. Keep that one here just to leave those dimensions. And that bottom one, as well. Yeah. And then there's a line in there, as well, you need to get rid of. Then just draw straight across. That's it. Ditch that line. Yeah, that's it.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: I'm not sure. I'm not sure if that matters.

AUDIENCE: Yeah. Well, we'll see if I finish. It's a line.

ANDREW MANZE: Still there. Yeah.

So now what we need to do is to dimension it how we want to do it. So if we just hit Dimension up here, what I want to do is create a dimension from this origin to this top left-hand corner. So I'm going to click first that point there, then that point there, and then drag it up to the top.

So we could use fixed dimensions, but what we want to do is to use parameter names that InfraWorks will understand and then populate that dimension with a calculated one that it calculates for us. So this is where the parametrics of InfraWorks is coming in.

So for piers, there are three known or required parameters. And it's basically the dimension from the center to the left-hand side of the pier, to the right-hand of the pier, and also the pier height. So you have to have those three.

So what we do is we type Pier cap Left Width equals and then we can give it a value. So it could be four meters or something. So Pier cap Left Width.

It's really important that you get it exactly right, and that it is-- you respect the capitalization as well. So capital P for Pier cap, capital L for Left, and capital W for Width. Because that is what InfraWorks is going to look for. It's pretty small on the screen, isn't it?

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: I put 4,000. But it could be 4,000, 5,000. It doesn't really matter.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: It depends on how-- When you drew the two sloping sides, whatever angle you chose, you'll get a slightly different value. It doesn't really matter. Just choose something, just a round number close to what the number is.

Bear in mind, if this all goes horribly wrong when we import it into InfraWorks, it's OK. Because we've got a-- I have a pre-prepared one which you can use instead, if it doesn't work.

So I'll press Return there for that. And that's where I'll go.

But it'll still say 4,000. So what we need to do is come down to the bottom here. And we can change, by clicking on this button, the representation. So if we say Expression, it'll actually write the value in so we can see what we've actually done.

And then I'm going to repeat for the other side. So from there to there, pull it out. And I'm going to call this Pier cap Right Width.

So what I'll do is I'll continue with this. And then we can-- we'll take a break until everyone's got these in.

So then I want a dimension from the center to the bottom there. And I want that to be 2,500. And then another one from there to there is 2,500. And then one from the center here to that corner, pulled out to here. And that's just called Pier Height.

So that's what you want to-- try and achieve that. Remember to get the capitalization right, though. Otherwise it won't work.

Have you done it before? Hi.

AUDIENCE: I accidentally let this line [INAUDIBLE] some other dimensions, not [INAUDIBLE].

ANDREW MANZE: OK. Let's have a look. There we go. You've got a 9 there.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: Yeah. No, that's OK. What we can do, we just deleted that. But it's still in the air, isn't it?

AUDIENCE: Still [INAUDIBLE] dimensions.

ANDREW MANZE: But it's OK We're not going to fix it. So if we do from here to here.

AUDIENCE: I can edit that later.

ANDREW MANZE: Yeah. So if you can do that. But if you want to get this down onto the ground you can put a dimension between these and call it zero.

AUDIENCE: Between these?

ANDREW MANZE: Yeah, that there. And pull it horizontally.

AUDIENCE: No, you want to it vertically, right? So you put [INAUDIBLE] down?

ANDREW MANZE: And then zero.

AUDIENCE: I know how to change the height.

ANDREW MANZE: Now you can change the-- this. Double click that to make sure we get it.

Oh, that's OK, buddy.

So I think most people have got that done, so we're going to press on, I think. So once you have this set up, as I've got here, you can then say Finish Sketch. That will finish that.

And then if you want to press the little home button, top right, you should end up with something like that. So you can leave it like that, or you can manipulate it into something like that. Just a shift [INAUDIBLE] like everything else.

And then what we're going to do is we're going to extrude this. So we're just going to use the Extrude tool. So we just click on that. And then it gives you this little handle which allows you to-- well, I could grab it if I was looking at the other side, but it doesn't matter. Make sure you have Symmetric clicked, like that.

And then this is the value for the thickness of the extrusion that we want to create. So we could put a value there, but I'm going to put a parameter. So I'm going to call it Thickness equals maybe a meter, something like that. 1,000.

So what will happen is we'll, instead of just seeing a number when we get into InfraWorks, we'll see Thickness. And then we'll be able to adjust it when we're in there. So if we just say, OK to that. Then we have-- that's how it'll appear.

So there is one thing that we do need to do, and that is go to the Parameters dialog. So you just click on this little FX button at the top. Gives you a little list of all the parameters that are currently running on this particular object. And to be honest, all I'm interested in is getting these boxes filled up.

You can change the names of the parameters here, if you want to. We don't want to at this moment in time, so I'm just going to click all of these. Just make sure they're all clicked. Ticked, rather. Once you've done that, hit Done.

And then, really, all that's left for us to do now is to export this in a format that we can pull into InfraWorks. So that's all the modeling for the pier done, really. So if we go to the Environments tab, you should see Infrastructure Part Shape Utilities.

Hit Export Template. And then you'll see the little dialog box, which just allows you to export it with a name to a certain place. So what I'm going to select, I'm just going to select my desktop. And I'm going to put it on there.

So if we just hit Browse, select Desktop, and then I'm going to call it My Pier. And then just hit Export. There'll now be a My Pier file on my desktop.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: I have to go because I've got another meeting. It's OK, mate. Let me know. It's OK.

AUDIENCE: To find distance [INAUDIBLE]

ANDREW MANZE: No, no. You can just type it in. So just type Thickness equals. And that should be-- Yeah. That's it. Just type it in. [INAUDIBLE] that's it. And then 1,000. That should be OK. Yeah, that's good. And then you want to do-- Yeah, don't save it. You need-- did you do the parameters at the top? FX. And then you want to take all of these. Yeah. All of those. And all of the export ones, as well.

AUDIENCE: Sorry about that.

ANDREW MANZE: That's OK. And then hit Done. Then Environments, Infrastructure Projects, Utilities, Export Template. There you go. It's linked to Desktop. Browse. Desktop. That's it. Just type a name. Whatever you want call it. And then Export. That's it.

So it's been exported, so I can close that down. Click Finish Infrastructure. And we're finished with Inventor now, really. So we don't need that anymore. But you'll see that, on the desktop, I've now got an IPT file called My Pier, and then I've also got some other files that InfraWorks will automatically use too, when we bring it in. OK?

So back to InfraWorks. And there is a way to bring that file and bring it to import it, so that it becomes part of InfraWorks. So we're not just bringing in a dumb shape. This is going to look and act in exactly the same way as if it was a native, by InfraWorks, bridge object.

So we do that in the Style Palette. So we just click on this orange one. I think it's under-- this one with the little pencil. Style Palette. You'll see the Style Palette pop up on the right-hand side. And then along the left edge, you see these parametric models. Hit that.

And then, there's one for Bridges. So we can double-click that. And then, you'll see, there's one, there's folders for abutments, decks, foundations, girders, and piers. Because this process works for all those parts of the bridge.

So this is a new pier, so we're going to put it into the Piers folder. And these are the piers that you'll see when you click the pier, and it gives you the alternative. So these are like the built-in ones that are supplied with product, and we're going to add ours into this place.

So all we need to do is click the plus at the bottom. And then we've got this new dialogue which allows us to pull in that new IPT file that we've just created. So if I just click on those three dots, go to My Desktop, wherever it may be, that's the pier that I've just modeled. Click Open, and then a few things will happen.

So you'll see it's pulled in the name, the description, which you can change. It knows what the units are. And then, if you look at Component Type, it already knows that it's for a bridge. It already knows that it's a pier.

And that's because it scanned the file, and it's found the three required parameters that we modeled in Inventor, which were Pier Height, Pier cap Left Width, and Pier cap Right Width. And you see it's put a tick next to all of those, because it knows it's found them.

It gives you a little preview at the bottom, which you can manipulate. So you know what you're pulling in.

And then there's a few things that we can do, which I'm not really going to cover. But these other two tabs are set up for creating multiple standard arrangements for your particular object. So you might have some company standards relating to dimensions, or arrangements regarding bridge parts. And you can specify those in here, and make maybe only those available to the user, if that's what you want to do.

And then under User Interface Appearance, this is where you customize what the user is going to see when they go to model this particular pier. So these are the values which will come through in the panel on the right-hand side when you click on the pier itself. And you can customize what they see and what they don't see.

So I'm going to make some changes here. You don't need to. But just so you can see it working, I'm going to turn off these ones here so that I only see the Pier Height, the Left and Right Width, and then the Thickness. But you don't need to do any of those. Not necessary for you guys to do it.

So when you're at this point, you can then click OK. And you'll see it'll add it in to this catalog-- which you can change the name again if you want to, or you can just leave it. So that is now inside of InfraWorks, and we can now use it. So just make sure everyone's done enough. Looking good.

So we can close that now. So we can close the Style Palette. We don't need that. And I'll just zoom in a little bit on this.

And then, if we just click on the pier itself, make sure it selects it. And then we'll see on the right-hand side, we have the information relating to this particular pier. And if we just click on this hyperlink, it will bring up the list of standard content. But you'll also see that your one that you've modeled is in there as well. And if you just double-click that, it'll model it in for you.

So you'll notice that it's not come in with the dimensions that you modeled. InfraWorks has calculated those dimensions, put them into those parameters, and it's modeled it accordingly.

So there's a couple of things we can do now. So you see this strange foundation which is up in the air. If we click on that, and on the right-hand side here, Height Above Ground, we can say minus 5.

And so you can see that's the parametric nature of that pier, that as we raise and lower the foundations, InfraWorks calculates what the pier height should be and models that Inventor file accordingly, in the same way as it's doing the width as well, from the deck. So if we look--

In fact, that's OK. I think you can leave that. If you wanted to change the thickness, you could also change the thickness as well. That was part of it. So down here, Thickness equals 1 meter. I could put that at 1.25, or something like that. It will change it.

So that's how you create Inventor content. So this is, obviously, really simple, because it's a class. But you can use this technique to create very, very complex components. And not just for piers, but also for the abutments, the decks, the girders, all the parts of the bridge.

What I will do now, I think, looking at the time, we've only got 10 minutes, really. Can I have a show of hands? Who is really interested in looking at the structural analysis side of this workflow? Two people. Maybe three. OK.

I'll tell you what I'll do then. I think what we'll do is we'll move on to the Revit side now. We'll get that done, and then meet me. Maybe us three can have a-- we can stay after maybe, if we run out of time.

So for the Revit side of things, we need to get this into Revit. So if we right-click on the bridge, there we go, you will see the center Revit. Create New. Just leave the InfraWorks template as it is. I'm just going to say Create. And I'll just create our Revit model for us.

So as I understood it, there was about half the room that have used Revit before, and half the room that haven't, by the sound of it. That was about right, I think. So we'll go through this slowly.

So there's an awful lot to Revit. But for the 10 minutes, just to get us some rebar in and detail something, we're just going to just go through it click by click.

So you should have this view of the bridge that's come through. If you want to see it in 3D, just click this default 3D view at the top. And you should see something like this. If you want to view it in a shaded view, you can come down to the bottom here, click on Visual Style, hit Shaded. It's a little bit. You see what that's done for you.

So that's a replica of what we produced in InfraWorks with our custom Inventor pier. So if we go back to the Plan View, Level 2-- And what I want to do is, for producing the drawings I want to produce, I'm just going to get rid of a lot of this extra stuff that I don't need in this particular view.

So I'm just going to click on the top here, one of these generic model components. Say, Hiding View, and then just say, Category. And that should leave you with something looking like that. And then, if we just highlight the deck, right-click, Hiding View, Elements. And then you should end up with something like that.

So what we're going to do is we're going to take a few section views that will allow us to place some of the rebar. Now, the bridge is not in an orthogonal direction, so it's a little bit awkward creating views and stuff like that. So what we can do is we can rotate it. We take the view into an orthogonal orientation to make it easier for us.

So if we just zoom in on here. And then we can go to Manage, and there's a button here. There we go. Project Location and Position. And I'm going to Rotate Project North this time. So we can hit that.

And then, there's a number of different options, but I just want to select the Align Selected Line. So just click on that. And then pick on one of these lines, here. And click OK. And then you can zoom out and see, you've got it at this angle now. But this is the right orientation to take our section.

So if we go up to the top here, we've got a Section tool. So we click that there. Not there. And I want to click somewhere there like that. So this is the line of whether the section is going to cut, and this is the depth of the section, which you can adjust with these grips. And this is the width of the section, which you can adjust with these grips.

And then you've also got a toggle switch, which will change the view direction. And if you click away from that and then double-click on the blue head, it will take you to that view.

So these piles are very long. So I don't actually need to see all those. So if you click on this Crop View, if you like, you can see there's some grips. And you can adjust that view like that.

And then we can take a second section vertically through that, like so. And I think, in this case, we'll turn it the other way. If we double-click that one, it will take us to that view. So again, this crop view is too big, so we'll just grab hold of that and pull it in.

And this is the view that we're going to do the rebar detailing in. So we'll just create a few bars just so you can see how it works. I just want to make sure everyone's got those two views. Are you all right? OK.

So what I'm going to do is I'm just going to go straight into some rebar. And hopefully, we'll get to the end of that bit, and that will be our lot that we wanted to check us out.

So all we need to do is to click on that particular shape. And then you'll see this Rebar button becomes available to us. We can hit that. Just click OK. And then you should see some shapes on the right-hand side.

So I'm going to choose this U bar, and you can see, as I hover my mouse within the section, it's sort of ghosting in the bar. And it's rotating dependent on where my mouse is. So if I bring my mouse down to the bottom, and just click, and then press Escape, it's put that bar in for me.

Now, if I want to view this in more of a solid mode, I can do is just change the degree of visibility from course to fine. And you should see the bar itself-- And then, we can make some changes to this bar. So if we select it, we can go up to the Properties on the left-hand side, and maybe we'll make that a 22 diameter bar, like so.

Now, if we want to see this in a 3D view, we have to change the properties of it. Because at the moment, if we go to 3D view, we can see that the bar is there, because we see the grips. But we can't see it through the shaded view, so we can make some changes to the visibility settings.

So if-- on the left-hand side, in this panel, there is something called View Visibility Graphics. And if we edit that, you'll see that under 3D View, I can tick both View Unobscured and View As Solid. And then you should now see that bar in there. And again, if you change the degree of fineness, you'll see you'll see the whole bar.

OK. So if we go back to this view, we may not want this bar to be a U bar that goes all the way from the top to the bottom. So we want to change the length. So the easiest way to do that is to click on the bar there, and then hit Edit Constraints. And then we can click on these bar handles and give it a value.

So we can say minus 3 meters, like so. And that'll bring that bar down. And we can click on that one there and say minus 3 meters. And then click Finish. And that's now a different length.

Now, say you want to put some bars going the opposite direction. The procedure is the same. We just click the section, hit Rebar, go up to a different bar shape, maybe this particular one.

But you'll see, it-- what it's trying to do is put it in that same orientation as we did with the U bar. So I want to change that. So I can come up to the top here and say, Perpendicular instead. And this time, we can bring it down here. And we can plant it somewhere like that.

And then we can do the same by editing the-- I'll tell you what we'll do. We'll change it to having more bars. So instead of having a single bar, we'll click up here and we'll say, Maximum Spacing, 300 millimeters. OK.

But what you'll notice is, is that this bar has gone to the cover line rather than respecting the bar itself. So we need to make a manual change for that. So, again, we use Edit Constraints. So we can see, this particular one, if we click on it, there's two ways of doing it.

You can use the grip. So we can pull it in like this if you want to. Or, if we go over to this side, we can do it numerically. So you can see this vertical line here is relating to this color line. So we can type in a value to pull that in.

And if we look at the bar, you'll see there's this vertical line here, which we've just edited. But this is also another constraint. If we click on that one, we get another value which we can change. And that puts it in the place that I want it.

Again, if you want to see that in the 3D view, you need to change that. So you should be seeing something like that.

We've run over time, actually. So I think, we're going to have to stop there. I'm sorry. It was the technical problems at the beginning, I think, which have caught us out. Do you know if there's another-- is there another class after this? There's no one else? OK. I'll carry on if you want to. So if you want to leave, you can leave. If you want to stay, stay and I'll carry on.

AUDIENCE: I have a question. [INAUDIBLE]

--so we can practice on our own?

ANDREW MANZE: Yes. I can provide you with a dataset. Yeah, of course I can.

AUDIENCE: Goes to my email, or--?

ANDREW MANZE: I'm just trying to think how best to share it. I think if you give me your email address, I'll upload it somewhere, and you can download it.

OK. So, similarly, with this U bar, we can make that-- we can change that from single to maximum spacing.

OK, you'll have the dataset, as well.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: No, no, it's OK. Yeah, I'll send you that. You've got the handout, anyway. So you can go through it, as well.

AUDIENCE: [INAUDIBLE]

ANDREW MANZE: Yeah. Yeah. No worries.

AUDIENCE: Thank you so much.

ANDREW MANZE: OK. I'll do it. Thank you.

OK, so there's just three of us left. So I'll just show you very quickly how we can change the visibility for these bars, then.
