creating a second floor

[rollie]

im designing a house and have now design the dowstairs layout in 3d. i would like to do a second floor and not quite sure how i will start this. do i do it completely seperate and paste it, or do i start extending it upwards on the original ground floor.

again really appreciate the help dude

I'd treat it as a separate entity initially in case you change your mind about the configuration. Tie it all together when you're 95% sure you have what you want.

Ya!..I agree Remark said!..I always do two dwg files,
separate objects file & union file per job!

how do you then copy and connect it to the first floor?
