I have a problem with and Pipe fitting Elbow that was created in Revit 2014. The Family flexes correctly and is correct dimensionally but when I use it, the angle that comes off a 45 elbow is slightly off. I made sure the connectors angle is set to the Angle parameter and the Radius is set to NomRad parameter. It the JPEG you can see the elbow angle is correct but pipe angle is not. The elbow works correctly at 90 degrees

Attached is a sample project with subject elbow. Its a long radius welded elbow with OD=Nominal Diameter. Thanks for your time Corey.
I believe the problems is that Revit is using the Family's Origin (intersection of the Origin Reference Planes) as the intersection point for the Pipe, and the location of your Family's Origin does not match what should be the geometric intersection point. You have a parameter called "LenA2" that is controlling the horizontal distance between the vertical Origin Reference Plane and the edge of the bend. I think you'll need to use a separate parameter here to properly calculate this distance.
Compare your Family with the standard Revit generic elbow Family. (See image below).
Thanks, great catch. Appreeciate your assistance. Yup all good, changed lookup table paramter from lenA2>>BendRad and then lenA2=BendRad*Tan(Ang/2)
Can I help you
Please show me how create a transition piping fitting,it is difficult,you can record video for me.
I would use the default "transition - welded - generic" duplicate and modify the length and the fitting outside radius parameters to suite your needs.
A transition is created using a blend with the top and base set to parameters for the two Pipe outside diameters. The length should be set to another parameter. Reference lines are then added for course and medium detail levels. Add pipe connectors to the blend faces and set to Nominal diameter 1 and 2. I would also add a material parameter and set that to the blend material to easily change.
