I am modelling a large office building that has a footprint that gets smaller on the higher floors.  I have all of the footprints in a single CAD drawing and have uploaded it to eQuest and have a few questions on how to proceed from here . . .

1. How can I assume one outline to be floors 1-10 and a second outline to be floors 11-20 and so on?

2. I was provided all of the outlines in one CAD drawing with them sitting side by side.  Would it be easier if i had them supplied as separate files?

Thanks,
Sol
