Revit Cut Extruded Roof

There are 3 primary sub tools that you can use to model roofs in revit roof by footprint roof by extrusion and roof by face.

Revit cut extruded roof.

For the purposes of this tutorial i am going to use the following simple building. In revit there are multiple ways to approach a modelling exercise. In this revit architecture tutorial i show you how to create an extruded roof form using the roof by extrusion tool. In this video we explore an alternate method of creating a roof in revit.

This is going to allow revit to cut the roof properly in plan. By using our dwg we find the slopes of two roof lines and their elevations for the rafter cut a simple two line. We will delve into great detail on each later on but to start let s look at the standard roof by footprint workflow. Modelling roofs is no different.

After adding a dormer cut an opening for it through the roof. Revit makes both vertical and horizontal cuts in the roof. Architecture tab opening panel dormer opening highlight the main roof on the building model and click to select it. Create the walls and roof elements that make up the dormer.

Open a plan view or an elevation view in which you can see the dormer roof and the attached walls. Join eric wing for an in depth discussion in this video trimming an extruded roof part of building roofs with revit. Dormer opening in a 3d view. The bad thing about extruded roofs is the fact you can t follow along with the footprint of your building the good thing is we can do something about that the objective of this video is to go to the plan view we will then create a void where our walls jag in and out this is going to allow revit to cut the roof properly in plan to get started jump into your revit roofs.

If the roof is extruded open an elevation view.
