Read angle of a fitting

Hello everyone,

First problem is solved, now my second question here. I like the option to read the vectors of objects in Revit. Now i want to read the angle between my pipe and the fitting. It is possible to rotate a fitting. Let’s say the starting position is faced to the top, sometime i want to rotate this element under 90° or even 60°. the fitting i mean is in the picture. Is it possible to read the angle between the pipe its connected to and the centerline of this fitting? I’m really curious about this.
