Let us change the Layers in a wall by Instance.
Example: 3 wall thicknesses X 2 Finish Types on both sides (X2) These are 12 Wall Types!
When essentially all we need is 3 Core walls with interchangeable finish layers.
If we could use an Instance based layer change, work would be MUCH faster and flexible.
In large projects - Who remembers if a certain type exists? with the certain finish...
Please apply to all layered elements - Walls, Roofs, Ceilings etc.
