    Vertically Compound Walls are made up of regions of different materials.

    In the Edit Assembly dialogue box, you can define the layers that make up the component structure as shown.

    The preview window shows the layers in the structure. The layers show their material cut pattern. You can preview the structure in plan or section and zoom or pan within the preview window.

    Assembly Information

    The top on the dialogue box lists the family name (Basic Wall), the Type name (Wall-Ext_102Bwk-75Ins-100Blk-12P) and the Total thickness (290mm – which is the sum of the layers defined in the wall), as shown.

    Layers

    When you specify the layers for the compound wall, you assign a Function, Material and Thickness. In the wall assembly, there is an important layer called the boundary layer and several layers attach to it either on the exterior or the interior side. In the Edit Assembly dialogue box, there is a layer called Concrete Masonry 100mm thick. This is the Core and on the exterior side a Fiberglass Batt and Brick, Common layers have been assigned. Similarly on the interior side plaster layer has been added.

    Based on this concept, the following illustration clearly shows the make up of a compound cavity wall in Revit Architecture.

    The top illustration defines the core layer (structure 1) and the centre of the core layer. The bottom illustration defines the wall finish faces and the wall centreline which is the total wall centreline.

    These wall location lines are important when drawing walls in Revit. In my next blog I will look at wall location lines when placing walls in Revit.
