Creating a Flat Roof in Revit Architecture 2015

revitfeat

Today we’ll be featuring a basic introductory tutorial from our new Revit Architecture 2015 training video series for beginners: creating a roof. While quite basic, it’s hard to argue with the importance of adding a roof to your structure’s plans, since some would say you don’t have a structure without it.

While the full 8-hour course also shows how to create gable roofs and more extensive modifications, this post will show you how to create a simple flat roof, familiarize yourself with essential tools and avoid a few pitfalls that can come with adding a roof to your drawing.

This lesson is adapted from Chapter 9 of the beginners Revit Architecture 2015 course by Bryan Meyers. You can check out the product’s free videos section from the new series for more tips before you buy.

Getting Started: Know Your Levels

Before creating the roof for your drawing, you will need to make sure it has a suitable level within your floor plans, and it’s a good idea to label it so. In our sample project linked above, you can right click on Level 4 under Floor Plans, go to Rename (as shown below) in the context menu and name this level Roof.

You can also define and rename Level 5 as the top of the parapet (TOP), in other words, the top plane of your interior walls.

Drawing the Roof

Now simply double click on the Roof level to bring up your roof view, looking straight down at your building. To bring up the correct roof drawing settings, click on the Roof toolset from the Architecture tab in the ribbon.

Since we are creating a flat roof, the first thing you’ll want to do is uncheck the box for Defines slope.

Now, select the basic Line drawing tool from the Draw or Boundary Lines panel in order to sketch the footprint of the roof.

Once the tool is selected, click on the top left corner of your structure to set your first point. Go straight down to the bottom left corner and click again. I this way, set the points of your roof perimeter along the edges of your exterior walls at each key intersection of your plans. Once you have clicked again on the starting point in the top left corner, the roof footprint will be highlighted with a magenta box. To finish, click the green checkmark in the tool ribbon.

You can switch to a 3D view and see your flat roof has been drawn.

Cleaning Up

Sometimes when creating a new roof, the tops of walls in levels underneath can stick through. Use Control+click to select all of the internal walls of your drawing, then from the Modify Wall context ribbon in the above right, select the icon for Attach/Top Base, shown below.

Now hover over your roof layer with your mouse cursor, and when you see the outline of the roof highlighted in blue, just click once. The tops of the interior walls you selected will now be joined flush with the bottom of your roof. It’s done!
