Drawing Roofs

3m 46s

In this course, Josh Bone will show you how to create detailed 3D models in ArchiCAD 20.

First you will learn the basics of ArchiCAD and how to navigate within the software. Then, you will learn how to draw walls, add stories, and place objects, columns & beams. Finally you will learn about documentation within the software and how to place labels, identify sections & elevations, and incorporate external file formats.

When you are done with this course, beginner level users will know how to create a detailed model using the most common authoring tools within the software while still maintaining flexible workflows that allow you to edit and make changes to your models throughout the different design phases. Intermediate level users will learn modeling techniques that improve their productivity within the software.

So lets begin with roofs in ARCHICAD. The first thing I want us to do is just move over here out in space. And what I'd like for you to do is I want you to start with a rectangular shape here in ARCHICAD. We're gonna go to our wall tool and we're going to start with a T shape. This is going to be arbitrary, we're going to set this up now and I want you to start with a dimension for a rectangular shape that's going to be set up 40 feet wide, so we'll hit 40, we'll go down to the next value by hitting Tab, we'll type 20, and we'll hit Enter.

So I have a rectangular shape that's 40 feet wide by 20 feet deep. Then I want you to go back in and just space here. Remember, we have our division set up, you can click, move over, rest on that point, as you rest there your guideline will appear, and you can move down where you have an even division of this space.

I don't want you to worry about that, I want you to come back in here, and just take and draw a rectangle that overlaps here, and a rectangle that overlaps here. I'll go back in, hold down my Command key, and I want you to trim out these elements. This is gonna be the starting example that I want you to use in the exercise for doing roofs in ARCHICAD. Roofs are very easy. There's a learning curve there initially, but I'm going to break this down here for you.

The roof tool in ARCHICAD has a couple of settings that you need to worry about. As always, geometry method. Is this a single plane roof, is it a multi-plane roof? The multi-plane roof is a great place to start. If you don't know what your roofs are going to look like, or how they're going to come together, we'll start with a multi-plane roof, we'll use here a complex shape, and then we can go back in and pick up the complex structure of the roof, we can keep it simple, so we can use a composite for the roof, we can set the pitch.

Here, I'm working in inches so I want to do three forward slash just to start. We're gonna do a three in twelve pitch. And then this is the plate height for my roof. This is where the roof is going to rest on that wall. So I'm going to set this up on my wall to be set up right now to 12 feet high, as my stories are set to 12. So this is the base height, this is where my roof is going to bear with a three 12 pitch.

Now that I've set that up, I want us to come back in here and I want us to just rest on our wall. We've chosen the multi-plane roof and if we hold down space bar and we click, it's going to automatically generate a roof based on the fact that I space bar / clicked on this plane it pushed that to that outside face of the wall. Let me do Command Z for just a moment.

Let me come back to the inside face, and space bar / click, and now what we can start to define here is by setting this up, where you use space bar / click, I'm going to hit Command Z again to undo, I'm going to hold down space bar and click, and I can now trace to the inside face of that wall. It creates an automatic roof at the plate height of 12 feet with a three 12 pitch, and what we've just now created, remember we can go back in and put a marquee, I'm just going to window around everything, and with what I have selected if I hit F4 on my Mac, double-click on my scroll wheel, I can see that I've automatically generated a roof within ARCHICAD.
