I am trying to export to CAD to send to my structural engineer and the structural engineer only wants to see the core edges of the wall and not the different layers of the wall i.e. doesnt want to see the any of the finsh or substrate layers.

You can set your wall layers up to whatever you want them to export as then just have him freeze it.

I have done so. the problem I am having is the subcategory "common edges" seems to be the only one that goes through the export. meaning, in the Cad dwg I see the common edge layer and delete it thinking that the structure layer is beneath it. when I delete the "common edge: layer there are no other lines beneath that line

Ah I believe I spoke to soon.  There is no way to separate the interior layers as you are asking to do.  I did find this "workaround" that may help you

I think the easiest answer is to copy monitor your project.  When you copy monitor walls, you have a choice as to what walls to copy with in the second model.  Our structural engineers do this and copy with core only walls.

SIMPLE

it been a while but I would like to revist this conversation.

WWHub, i believe you are talking about revit model to revit model. unfortunatly the structural engineers that we typically use do not use revit. they are on the CAD platform still. so my intial question is pertaining to exporting to CAD. I would like to isolate the 'structural layer' and i believe to do so i will need to seperate the 'structural layer' from the 'common edge' layer.

Use a temporary file for export to CAD where you replace the walls with a core only wall.  Before you set the wall to the core only wall, be sure to set the wall's location to center of core.   You should be able to do all of this from project wide rather than individually.
