I have tried to draw a refurbishment plan using wall styles, but it was unsuccessful. The plan had several different wall thicknesses. If you use wall styles, each wall thickness needs its own wall style.
In just this small area, there can be five different wall styles. But it is not just making the wall styles, it is when you come to edit the walls for the demolition and proposed plan. If you use walls styles for the existing, then you tend to make wall styles for the demolition plan.
