Ok, i know in a perfect world when starting a project , and you have intentions to throw a legit site plan into it, you prolly should use the actual elevations (from the civil drawings) but let's say you go through the project just using 0'-0" for finish first floor, and then say you get the civil layout with the actual elevations, shouldn't it be easy enough just to go into an elevation view and type in at the first floor elevation the new elevation ? that is what i understood you should be able to do anyways, and as you prolly guessed it, i do that and i have like 63 errors/warnings, the only other thing i can think of which will be a pain is to just do the math by taking the actual elevation of FFL and get the difference from the civil and then plot them from 0'-0". anyone have any other suggestions?
