the commonly met standard in my country is that membrane layers, like water insulation are drawn as dashed line over layer they're placed on in section or detail. The question is - is there a tool to do that with composites? What I've done is placing zero thickness layer with additional line - but the lines overlap and it doesn't look quite right. Another possibility is to offset that zero thickness layer for example 1 cm into the next layer - but then I expect that problems might occur when creating schedules. I've attached an example
It's not a new problem. Last time I checked I think GS advised against 0.0mm thickness composite layers, but this may have been lifted in 24 & 25. You can assign a thicker pen to draw the membrane line, although it won't be offset like your image. Currently I leave the membranes out of my composites as too often they don't merge correctly at junctions and you don't really need to show them until you start detailing those junctions. From the BiM perspective it isn't good either, but our expectations are a bit ahead of the software when it comes to this level of detail.
