@genesco said: Hey thanks for this, this is pretty close for the larger roof (top left) but not for the one on bottom right. [attachment=0:1q4lxag9]<!-- ia0 -->tricky roof2.jpg<!-- ia0 -->[/attachment:1q4lxag9] Suggest you think about: looks like a line missing on the bottom left cricket or dormer Think you should be able to use the move tool to pull up to get slopes etc once you can include a slope ref for the dormers. What you have looks strange to me can you post what you have for the SU model vs forcing us to try and deciher the pics. Give a size ref also so the pics can be set to scale just some thoughts
