"if" Statements in User Defined Checks

[[Ny...]]

hi, first time posting here

I am trying to choose to report the circle without an error, and if they are both calculating, the closest to nominal.

But if the inputs contain a un-computed value the whole result will also be un-computed, is there a way around this?

Thanks in advance,

Nyall

I think I have the solution... if anyone else comes across a similar  issue, the proper test for if an element is uncomputed is:

x = "???"
if  A.actual.computation_status != INVALID:
    if B.actual.computation_status != INVALID:
        if abs(C.nominal.diameter - A.value) < abs(C.nominal.diameter - B.value) :
            x = A.actual.diameter
        else:
            x = B.actual.diameter
    else:
        x = A.actual.diameter
else:
    if B.actual.computation_status != INVALID:
        x = B.actual.diameter
    else:
        x = "???"
x

Interesting, I didn't know you could use custom python code in the user defined, I was always using the basic functions in the fx dropdown. We measure difficult features and I many times need to construct many feature to get an average or to avoid question marks. This will help me in the future, thanks.
