Hi Amdeck

There is not a software to correct this, but I can explain other method to do this--> select just one corner of the roof--> Edit--> Rotate --> write the exact angle--> OK --> the arrow will rotate--> negative angles go clockwise --> positive angles go counterclockwise

Just in case, one of my Customers solved a similar problem downloading and installing this patch

If you continue to experience problems, send me the file and I'll check it
