Hi,
Besides the line-based detail item family, possible to create the symbol (Pattern: ---xx---xx---xx---) and place along the line & curve, e.g. site features - Railing/Fence?? Hope to have the same result as the symbol line drawn in AutoCAD.
Yes. You can create a curtain wall type using a custom panel family, which has no geometry except for a nested generic annotation symbol. We use that to show fencing and the likes.

The symbol can be parametric for different types.
