I guess everyone has there own system.
For example, we only show a ceiling height dimension on the front elevation,
and then again on the wall section, and that's it.
I have houses that have 3 different ceiling heights on the first floor alone.
So in the wall section I say "See floor plan for ceiling height"
One of them even had the foundation, first floor plan,
second floor plan, and roof plan all on top of each other. I can't stand that....
Well wouldn't you know it, that's the way I like it. Not that it's is the "Right Way".
I find that it works for me. Usually foundation, flr 1, elect 1, framing1, flr 2, elect 2,
roof framing all in model space , sometimes HVAC 1&2 also
By turning all the layer on I can verify alignment between floors.
I can turn the first floor & foundation on and stretch an area so they are updated
all at once.
I can draw a column on the first floor & use "Copy to Layer" to put the column on the
foundation & the second floor. Just some of what I like about it.
My title block is x-ref into paperspace which means I have quite a few copies of it but
as you know model space has enough objects in it.
