Currently modelling a building where my ground floor has rooms at three different heights -> staircase finishes at 12m (floor height) and a gym finishes at 7m and finally my offices/toilets/circulation which finishes at 3.6m. My first floor finishes 7.2m.I've tried to create two separate flat roofs. The first floor flat roof at 7.2m and a ground floor flat roof which says it starts at 7.5m. The ground floor flat roof consists of 2 sections both drawn from a 3D tool where one starts at the staircase 12m height and the other starts at the gym 7m height. At roof setup the model says ground floor (roof at 7.5m). I get a ton of warning messages after I try to apply this. Is it possible to alter this function to allow multiple roofs at different heights to be made to a single floor. Instead of one roof per floor?
Both roof sections shown are from a ground floor room (Sports hall and Staircase and finish at different heights)
I can see from your screenshots that you are not running on the latest version of the software. This will likely explain any modelling issues you may have been having with the software, as Update 9 is vastly improved from a stability point of view. It contains an entirely new interface to the roof modeller and resolved many issues such as the error message you show above.
I would suggest updating as soon as you can.
