System families, such as walls, floors, ceilings, and roofs, are compound structures. That means that they are comprised of a series of layers, with each layer defined by its function, material, and thickness. Some of the family types are simply defined by one layer.

Adding compound layers to the Wall

If you would like to add different layers in a wall type, such as finishes, plaster, cladding, air barrier or multiple core layers such as bricks, concrete, stone, etc; you can do this by editing the compound structure of the wall.

Each layer in the compound structure has a function which define how two compound structure elements would join with each other.

• Understand layer functions

Compound wall layers can wrap at the ends or at openings. This is particularly useful where finishing layers need to be wrapped at the walls with end cap or at openings.

• Understand how layer wrapping works

Modifying Vertical Structure of the Wall

Sometimes, walls not only have compounded layers in its thickness, but also vertically in their sections. Learn how to create vertically compound walls using this Video Tutorial – by Autodesk.

Layers

To create a compound wall with multiple layers,

• Open the Edit Assembly Dialog box and add layers to the walls.

Vertical Structure of the Wall

Sometimes, a project requires vertically compound walls that have multiple layers in a vertical section of the wall.

Vertically compound walls can host sweeps and reveals – which adds and cuts a profile on the wall respectively. This is useful when adding details such as parapet block,  cornice, molding or a cutout to the wall.
