OPPM SS6 - Catalogue - how to create elbow and reducer with straight part at each end

Hello everyone,
I want to create a catalog for pharmaceutical equipment (pipe, elbow, reducer, ...).
Fitting (elbow and reducer) are welded and have a straight part at each end.
In attachment the picture of an elbow and a reduction.
Can you tell me how to enter the parameters in their respective table.
in the meantime,
Best Regard
