I was looking for a way to obtain the envelopes filtered by load duration which are important in timber structures analysis according to EN 1995. I found a way and share it below for users who would appreciate it but didn't know how.
It relies on... result combinations and a filter I didn't know existed for a long time. I recorded a short video which is too heavy for this forum, so I made it available on YouTube:
Thank you Frederick. To be honest, I didn't even know that this filter for LDC is available 
. Thanks for sharing.
In a few weeks, there will be an easier way available too. We will offer new Design Situations for ULS where the envelope will be created automatically:
Great improvement! A smoother integration of fragile loads deflection limits would be great too, at the moment it's too convoluted to be practical IMHO.
Thank you for your feedback.
Could you please describe your last comment in more detail? I have no idea what you are talking about. Thank you.
I am referring here to the deflection checks regarding secondary finish elements whose limits depend on whether the element concerned is "fragile" or not.
Practices for these checks vary greatly from one country to another, due to habits but also many documents complementing or pre-existing before the Eurocodes.
To my knowledge, the common point is the need to verify deformations resulting from loads applied after the implementation of a secondary finish work (for example, the weight of a ceiling and the service load applied beneath a floor on which a screed and tile on a wooden substrate are already installed).
Considering the order of implementation and the factors involved in the verification of this specific deflection is not easy to master in RFEM at present. The instantaneous deformation due to loads preceding the secondary finish element should not be counted, but the part due to creep should be, for example.
Hoping that Discourse translation will allow us to communicate as clearly as possible 
Thank you very much. I have talked with our French team. We will see what we can do.
