Ahh !! I thought you may have overcame that problem
This is why I stopped my construction kit a few months back because of this issue....... BUT ITS NOT IMPOSSIBLE.......There are 2 ways
All these pics of my test kit are using.... "page up/down" ......in "F9 Mode" to place the upper floors but its fiddley..... EXCEPT THE LAST ONE ON THE END..... This segment I created at that height so basically its always that high.....
But it seemed I would have to make for example.. ( Floor corner bottom......then....floor corner second level...then......floor corner third level.... )
It would have been duplicating so many segments at different heights I figured it would be to confusing so I scrapped the idea...
I thought maybe you had found another way around it
So.... if you duplicated every segment in your model program at a second level and third level Height for instance ... it will work flawlessly... but that's 3 lots of 60 segments ..
