DD Wizard multiple shell modeling issues

Hi group,
Thanks for the years of topic help and resources you have provided. This is
my first time asking a question so here goes.... I'm doing some pretty
simple modeling in the DD Wizard and have run across this issue with shells
for the first time ever....
Whenever I add the 5th floor to this structure, it ALWAYS offsets a set
distance even though I have "directly above 4th floor" selected. I have
tried to redraw the floor numerous times, delete and re-add, specify exact
coordinates, etc. Alas, it always depicts the floor offset. Any help on
this is greatly appreciated.

My first reflex was that you should specify exact coordinates, but it looks like you?ve already tried that? did you specify exact coordinates for ALL floors, not just the ?problem? floor? When I build a model, I specify all floors at (0,0,Z), where obviously the z-coordinate will vary with level.

Nathan,
Thanks! The culprit was indeed on a different floor. Not sure why it only
became an issue on floor 5 but your suggestion worked. I was hesitant to
specify exact coordinates from the beginning due to a hodge-podge of
autocad files/generations/drafting companies we received for this project.
'Exact Coordinates' is my usual method and this most recent issue has
proven it is still the best method.

Hello
Would you tell me how a building with two shells for conservation of energy could be designed?
