    Setting the value of the rotation is not straightforward. Below is an example:

    testCS = ExtAPI.DataModel.Project.Model.CoordinateSystems.AddCoordinateSystem()
testCS.CoordinateSystemType = CoordinateSystemTypeEnum.Cylindrical
testCS.OriginX = Quantity(0,"m")
testCS.OriginY = Quantity(0,"m")
testCS.OriginZ = Quantity(0,"m")
testCS.PrimaryAxisDefineBy = CoordinateSystemAlignmentType.GlobalZ
testCS.AddTransformation(TransformationType.Rotation,CoordinateSystemAxisType.PositiveZAxis)
testCS.SetTransformationValue(1,45)

    To flip the CS, one can use:

    test.AddTransformation(TransformationType.Flip,CoordinateSystemAxisType.NegativeXAxis)
testCS.SetTransformationValue(1,4)

    where the second value ranges from 1 to 6 and accounts for +X, +Y, +Z, -X, -Y, -Z respectively.
