Lew - I'm guessing you meant me - I guess when the forum moved my signature went away, I fixed it, heres a pic.
The dashed stuff is a view to CAD from the as built plan. I turn off almost all the layers, set everything to dashed (I have a layerset) then view to CAD.
In CAD I shift select and block everything, E-FLR-1, E-FLR-2 and so on.
I then copy\paste (hold position) the CAD block into the plan, sent to the bak, on a locked layer (layer set again).
Once the as built is complete, I save, then save as the new plan. As I demo a wall, it uncovers the screened dashe wall\door\windows, leaving a demo plan.
It would be equally easy to superpose a stack of floor plans, showing whatever info, lineweight and color, onto a site plan, very similar effect to the advanced use of reference layers sets in LAyout, but able to address multiple stories. You could view to CAD the first floor roof plan, paste them into the second floor plan, then either reference or view to cad the 3rd floor roof. Or display all 3 floors of a split level. Or whatever.
