The new way of handling roof since AC15 isn't fun at all. Some features are great, but the way of what lines at the bottom of the roof that are 'locked' when changing thickness och angle of roof are making me frustrating. Most of the constructions I have done, the bottom of roof is the 'locked' position and then we are building the roof upwards. But since AC15 the top of the roof is the 'locked' position in xy-plane (but it pending up / down depending of the thickness). ???????????????????? Are there really people that like this new behavior????
