I can't quite understand what you're saying... Are you using components?
Ah OK thanks, if I can get a decent floor for the component this should work!Make one new floor "in the ground" and make it a component (select all the floor, right click, "make component"). Then copy and paste it anther five/ten times to make a group of five/ten floors. Then just add them to your building and keep copying and pasting them as it reaches the height you want.
Don't forget to make the cieling fit with the floor above it. Basically make each floor a part of a jigsaw puzzle. You can even do components for helical buildings, just make sure you rotate them properly.Ah OK thanks, if I can get a decent floor for the component this should work!
