Join Shaun Bryant for an in-depth discussion in this video Creating a building pad, part of Cert Prep: Revit Architecture Certified Professional (2016).
- [Voiceover] We're now in another chapter of our Revit Architecture Professional Certification Preparation Course. We're now in a chapter all about modelling. Now, when you work in Revit Architecture, you are developing a model. You're not just working with 2D flat plan drawings, You're developing a 3D model. So you'll notice we have a new Revit project open. It's RevitProject_PAD. And we're going to look at creating what is called a building pad in this particular video. Now, you can download the RevitProject_PAD.rvt file from the lynda.com exercise files and use it to follow along with the video.
Once you've got it open and saved locally wherever you want to save it, go to the project browser, and just go to the default 3D view there. You might need to expand it out, like so, and double click on the 3D in the brackets. And you can see there, we've got a simple building, and we've got this big brown thing here. That is a surface, a topographic surface, or topography. And basically, that's the ground that surrounds our building. Now, what I'm going to do is I'm gonna hold down the shift key and the wheel on the mouse to do a little quick manual orbit.
Now, if I do that and just look under the ground, so to speak, from below, you can see, look. There's our walls here. And you can see there's our topographic surface sitting there like that. Now you'll notice that the walls are just going straight into the ground. Now, if I go over the view cube here and click on the home symbol, that'll take me back to the original view. Now, what we're going to do is we're going to develop a building pad. Now, the only way that you can develop a building pad is to actually have topography in your model, what is known as a toposurface. And you can find that in the massing and site tab on the ribbon.
There it is there. Model site, and there's toposurface there. And you can define a topographical surface in a site plan or a 3D view. So there's my surface there. This brown surface here. Now I'm gonna go back to the level zero floor plan here in the project browser. And there's my level zero floor plan. Nice and easy to see. I'm gonna stay, though, in the massing and site tab in the ribbon, and I'm gonna come up here now and click on building pad. And this adds a building pad from a closed loop that you sketch on the toposurface.
So I'm gonna click on building pad, and can you see, we go into sketch mode. Now, I want to develop a building pad that offsets by half a meter all the way around the building outline. So I'm gonna go to the options bar here, put an offset of 500 in and press enter, and then what I'm going to do is I'm gonna use this draw panel here, and use this icon here, pick walls. So when I hover, can you see I get a dashed line? That's my building pad outline. So if I click on each of these, the pink sketch line kicks in like so.
And as I come around like that, you can see that there's my building pad going around like that. So, it needs to be outside the building 'cause I'm, in essence, developing what is a pad around the building. That might possibly be a pad foundation that the building actually sits on. And I might develop that later, but the idea of a pad is that you're cutting a hole in the topographical surface. So when I click on a green tick, like that, my pad has gone in there. And if I go into the site plan now, double click on the site plan there, you can see that when I click on the building, doesn't seem to be any sort of pad or anything showing.
Now, it won't show until I go back to my 3D view here. So if I go back to my 3D view, can you see there's my pad around the building? Now if I hold down shift and hold down the wheel on the mouse and do that manual orbit again, there's my pad sitting there, sticking into the ground. And that's what you would normally develop when you're modelling. You always have a pad for a building. You wouldn't stick those walls directly onto soil. So my pad is there like that, and it's sticking into the ground. It's like a foundation pad. It's not an actual physical structural foundation, but it gives you a pad to put your building on inside that topographical surface.
You would always make sure that that surface is flat, for example, to place the building on it. Now, the pad itself, as you saw there, is very quick and easy to develop. And you can see there, it's the little grey one in the 3D view when I deselect it. And again, I can go back to the home tab here in the 3D view, and you can just see the pad there, going around the edges of our building. Now that pad is there for a reason. It's there to place your building on. So if you've got big, sloping topography, you can, in essence, cut that flat pad out of the topography to place your building on in Revit Architecture.
Once you're finished with this course, you can feel confident taking the Revit Architecture 2015 Certified Professional exam.
