I have drawn 440 building footprints in CityEngine. I have taken care with the edge I have drawn first to help me control the orientation of gable and shed roofs. In case I have made a mistake with the first edge I have added a 'roofIndex' attribute so I can change the orientation of the roof where necessary.
I have found that when I re-open the project some of the roofs have changed their orientation since I saved the file - I'm not sure how many buildings have changed because the effect is mainly quite subtle but in the case of long-thin buildings with a shed roof the effect is very obvious because the roof becomes enormous.
Is this a known problem (2011.2)? Does CityEngine forget which edge was drawn first? Does it forget the change to my 'roofIndex' parameter? Would it remember the first edge better if I used imported shapefiles? Could I be doing something wrong?
It's very difficult for me to spot a pattern to this because it's difficult to be sure where it is happening.
Can you test this with an installation of the CityEngine 2012 TRIAL ?
I'm afraid I'm not getting CE 2012 trial to work - it just hangs on the splash-screen.
I think I meet minimum system requirements...I have: Windows XP Professional x64 Service Pack 2. NVIDIA Quadro 2000
I've rebooted since I installed it.....any suggestions? (The machine on which I have 2011.2 installed is not connected to the internet so I trying to install this on a different one).

I'm sorry, I forgot I was mucking about with the convexify command at the beginning of my cga file......it's all my fault. This thread can be deleted if you like.
