NewElbowFitting returning null

[GeomGym]

Jeremy's recent posts about rolling offsets of pipes has been pretty helpful for me to advance MEP importing.

But I get a null value returned from NewElbowFitting without an exception.  Can someone please help?

It's possible I need to set something up in the project, I'm not an expert with services by any means.

I've attached sample code and you can download revit project here:

Thanks,

Hi Jon,

Your code is correct, only the example model you attached contains pipe place holders, which do not have fittings, as such it's not supported to place an elbow fitting. I have tested with them as pipes and it does place the elbow as expected.

Hi Will,

Thanks for looking (and the answer is embarrasing).  I hadn't detected the place holders, I checked my original code and found the cause and it's now fixed.  Appreciate your response.

Cheers,

Jon

No worries, I put it down the API swallowing the error, would've been really helpful if it raised an exception instead.
