We skipped over many additional features to give you a handle on essential workflow the user interface and making modifications to the model. In this chapter we ll cover more-advanced features that are available anytime you re modeling in Revit. As you ll see with a little refinement and creativity you can make a wide range of building components with the standard tools. In this chapter you will learn how to do the following Take advantage of advanced wall features Work with advanced roofs and slab editing Work with railings Basic Walls Advanced Modeling Techniques Walls are made from layers of materials that represent the construction assemblies used to build real walls. In Revit these layers can be assigned functions allowing them to join and react to other similar layers in the model when walls floors and roofs meet. The wall core is one of these special layers and understanding it will help you when designing your walls. Wall Core Revit has a unique ability to identify a wall core that is much more than a layer of material. The core influences the behavior of the wall and how the wall interacts with other elements in the model. Every wall type in Revit has a core material with a boundary on either side of it. You can dimension to these core boundaries designating the location of structural wall components rather than finish materials. The core boundary can also be used when drawing host elements walls floors ceilings roofs . For example you can constrain a floor sketch to the structural stud layer of walls by using the wall-core boundary to create the sketch. If walls change size or are swapped the floor sketch maintains its relationship to the core boundary and will auto-adjust to the new wall. To access and edit wall-core boundaries and material layers select a wall and .
