In-place Cavity Walls

If your cavity is a constant width along the length of the wall (like the angled exterior wall shown on the right) you can just add the necessary layers to a basic wall family, but if you have undulating cavity walls, like we often do, you might want to consider an in-place wall family like the one illustrated below in blue.

This wall is the sum of two 9' tall extruded shapes in plan view... one for the overall mass of the wall (thicker line) and one for the stud layer (blue). The challenge with this approach is in getting the wall to show properly in coarse AND medium detail modes.

One way to achieve this is first to set the visibility settings of the stud layer element to hidden in coarse mode (select the stud layer element while in the family editor mode and set the element's visibility settings). The other setting your going to want to set is to assign the stud layer element to the Common Edges subcategory (within the instance properties of the stud layer element). This will thin the lines to match the stud layer of all the surrounding wall families. Use join geometry to get the surrounding walls to cleanup when they meet your in-place cavity wall. If anyone has anything to add to this issue please feel free to comment.
