I may identify the angle of a plane, but I set the beginning and ending points with a specific dimensions. Remember, the mechanic (carpentry) doesn't know high math and will not have a transit on the jobsite. And if you have drawn this in CAD correctly and accurately, the program can tell you the angle.

Figure out the X and Y dimensions of the starting and ending points of the angled wall. If the 15 degree angle runs the Y dimension figure the total height at that point. then divide the height by the lenght of the angled wall. example- The X dim is 4' The Y dim is 12' The angled wall would be 12.649 feet. If the pitch of the ceiling is 3/12 then you would have 3*12/12.649=2.846 or 2.846/12 pitch. Hope this helps. _________________ Designworks
