This might by old news
If you have an Arch model Linked in to your Struct model you can actually select items (columns, slabs, roof etc) in the linked in Arch. revit file and copy them into your model. I have done that now for a few projects to get the columns, slabs etc in the same location as the arch. – it is way faster than draw them yourself.
It is similar to C/M but without the monitor option.
