There is an option in Management Tools > Defaults > > Drawing Presentation > Colours.
It allows you to Use colour ByLayer in arrangement drawings for Visible lines. In that way, you can set objects (like Concrete) to a layer using Model Role, and have them display using the ByLayer colour on the General Arrangement Drawing.
However, I would like to see a similar option as this available for the linetype to go to the GA as ByLayer. That way it would be easier for people onsite to identify the non-steel elements they don't have to worry about, because using BYLAYER I have set the colour and linetype to make those elements different to my steel.
