In revit there are multiple ways to approach a modelling exercise.
Revit cut extruded roof.
Modelling roofs is no different.
For the purposes of this tutorial i am going to use the following simple building.
Create the walls and roof elements that make up the dormer.
Family and parameters family category select roofs or whichever type requires a cut provide a name for the void select extrusion or alternative from forms draw profile for the extrusion and provide depth value properties for the extrusion identity data select void use cut geometry tool to cut the void.
If the roof is extruded open an elevation view.
Architecture tab opening panel dormer opening highlight the main roof on the building model and click to select it.
In this revit architecture tutorial i show you how to create an extruded roof form using the roof by extrusion tool.
Open a plan view or an elevation view in which you can see the dormer roof and the attached walls.
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.
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.
We will delve into great detail on each later on but to start let s look at the standard roof by footprint workflow.
By using our dwg we find the slopes of two roof lines and their elevations for the rafter cut a simple two line.
Revit makes both vertical and horizontal cuts in the roof.
Dormer opening in a 3d view.
If the roof is extruded open an elevation view.
