LJade: Here is an example of what I mentioned in my previous post. Note that the channel supports the steel decking, and the decking supports the concrete. The rebar is embedded in the concrete. Note the flashing and canted drip edge in the example as well.
@Steven P not sure if this is what you mean, but I have pick attribute in say title block in a layout and it will copy that attribute value into the correct attribute in all blocks of that name, I think also a do multiple atts, handy when say you change a project description, updates all layouts etc.
