Awesome work, very tidy.
I just returned to Wed modelling in the last few days and its no easy task for me, even with all precautions taken and thats because I just used a model level to get the plan but forgot about old stuff like large walls seperating areas, none flag etc...
Its good to be reminided of the mportance of planning before building, would save a whole lot of grief.
...so respect! good work.
